Garmin Battery Issues

 

I have two Garmin 750's. Gave one to my son and one for me. They are approximately 8 months old. Both units have battery issues. Has anyone else with 7XX series units had a battery problem?

Lots of misinformation

BobDee offered the most factual information I saw. I think people get confused and pass bad information as they think batteries are batteries. Not so. The batteries in these units want to be shallow cycled. Deep discharging them, without regard to what people think they see, will shorten the life of the battery. You may have run your cordless phone down once a month 20 years ago but not these. Another comment was made about the charging temperature limits and that was true too. Consumer grade LiIon batteries can/will be damaged when charged outside of the temperature limits mentioned. One comment was made about that information being from 2006 but it's still true today. LiIon cells have high capacity, good discharge curves, fairly long life and low weight but are very sensitive about how they are charged. Oh... and most laptop and handheld device batteries have been LiIon for many years now. OTOH... that does not mean you can't get weak or defective LiIon batteries right out of the box. In addition, most sources do not recommend buying extras to sit on a shelf. This is because, more so than other types, LiIon cells are essentially dying from the time they roll off the assembly line although they do generally outlive the 18 to 24 month life expectancy. One other thing... don't puncture one. What's inside reacts violently when it gets out and meets with air...

Thanks for the info...

Maybe not exactly on topic, but close. I'm planning to use the GPS in pedestrian mode while city touring this summer and one obvious concern is battery life. Has anyone tried this:

http://www.gomadic.com/garmin-nuvi-760-emergency-aa-battery-...

or something like it and have any recommendations or comments? The plan is to get something like this to be able to recharge it during the day while walking around. I'm expecting maybe 3 hours out of the battery from scratch but that probably won't be enough for a whole day, even if turned off when not needed.

Yes, I tried it. It does work. One word of caution though, I intended to use NiMH batteries. NiMH batteries are a few thousandths of an inch larger than alkalines and 4 NiMH batteries would not fit into the Geomadic battery compartment. I had to get a battery holder at Radio Shack to make this scheme plausable. I emailed Geomadic about it. They did respond by telling me that my batteries were too big and not to standard. Well, I did check specs and my NiMHs do conform.

I do agree though that the 750 battery has a dismally short period before needing a recharge. Some say to turn display brightness down. Well, in bright daylight, if it isn't set near max you can't see it. Garmin's specs about this are grossly exagerated. My first 750 would get only about a half hour. They replaced it and the newer one does substantially better but nowhere near what they say it should.

Nuvi's are intended to be operated in a weather controlled environment and plugged into an external power source. Its really not an outdoor GPS even though it has provision for walk and bicycle modes.
I think that if they intended it to be used this way they'd have made available a bicycle mount.

I can't speak for farrisr, but when I returned my unit, it was shipped out within 24 hours of receipt.

It does depend on whether support said they would replace or repair. It also depends on whether they have to inspect the unit first.

You should receive a replacement within 10 days of THEIR receipt of the defective unit. Be sure to keep the tracking number in case you have to nudge them.

Try this... from Garmin

I sent Garmin support an email regarding the declining battery life on my 750. This is what they sent back:

1. Connect the unit to the computer via USB cable
2. Once the screen with the word GARMIN and the picture appears underneath it press and hold the power button to the
on position
3. Allow the unit to power off and it will power back on and go back to the same screen
4. Allow the unit to fully charge for 4 hours
Once the 4 hour time period has expired try and power the unit on The battery icon should have 4 green bars in it.

Now I did try this yesterday and it did seem to improve it a bit. When I got up this morning I turned on my 750 and it still had four bars. Before I did what they suggested it would usually only have two bars after setting overnight. It actually went about 30 - 40 minutes before it dropped to three bars. Then after another 15 minutes it dropped to two bars and the low battery warning started.

Not where I want it to be... or where I think it should be... but it was an improvement from where it was.

Battery Life

Battery life will also be impacted by how you charge the battery. To extend the life of your battery, try to never let it drain completely. These batteries do not have a memory, so it will not hurt them to be charged prior to being drained. DO NOT ALLOW THE BATTERY TO COMPLETELY DRAIN. This will cause the battery life to shorten considerably.

Also, be aware of the temperature of the batteries. These lithium ion batteries can produce a LOT of heat, and there have been reports of melting or thermal runaway in products using lithium ion batteries. If you feel the unit getting hot to the touch, do not hesitate to call and have the unit replaced. You do not want to have a fire because of a defective lithium ion battery. Remember Dell computers?

Everything you have said is true. However I'd like to point out that with modern electronic devices, it would be almost impossible to completely discharge the battery. This type of battery requires close monitoring of charge/discharge conditions (state of charge, temperature, current, etc.).The monitoring circuit will power the unit off or terminate the charge before battery damage occurs.

As I remember, the Sony Lithium-Ion batteries had problems with their seals. They allowed air and moisture to get into the cells. As you know, Lithium reacts VERY STRONGLY with water, generating a LOT of heat and setting the computers on fire.

The nuvi 3xx/6xx series happily displayed when the charge cycle was complete ("Battery charging complete"). All nuvis after those models -never- gave you that simple message. Whether or not it's a bug or a "feature", Garmin never felt the need to fix it, despite being such a simple issue. The diagnostics screen will in fact tell you when the charging cycle is done but alas, the GPS while NOT in diagnostics mode cannot. Sad but true...

Most other rechargeable items have this feature and alse indicate how much battery power remains. It doesn't make sense that Garmin doesn't do this.

Bad Battery Again

Just got a replacement 750 because of battery issues....guess what....the battery in the replacement is bad...won't hold a charge for longer than 15 minutes....sending the replacement back for a replacement. I am starting to wonder about Garmin from my own experiences and from others. This next replacement had better work or I am switching to Magellan. If Garmin was smart they would build these things so the consumer could replace the battery. They would be $$$ ahead instead of replacing the units.

re: Bad Battery Again

How do you charge your units? I use my Garmin charger that plugs into AC outlet to give the units a good full charge once in a while when they are showing the charge is low. My 760 will still last 4 or more hours on it's own battery and the c550 even much longer. I found when I just charged it by USB or car power cord the battery never seems to have the same lasting power as when I use the AC charger.

no problem so far on my Nuvi 750 but the battery does not last as long as the Nuvi 680 battery did. Got about 5 solid hours on the 680 which is great in pedestrian mode. Lucky to get 3 or 4 on the 760

How to replace the Garmin battery.

Here is a link on how to replace the battery on a nuvi 760. It will most likely void your warranty, but this may be useful to those that have older units.

You 760's battery doesn't know the difference between the Garmin wall charger, the USB port on your computer or the car bracket. A charge is a charge is a charge. Any difference in battery life might be because you aren't leaving the 760 on charge long enough using the car pwr cord or the computer.

The USB port supplies only 5V vs 12V from the car or the wall. The USB port takes much longer to charge it.

If you are going to compare apples to lemons, the wall charger runs on 120vac. So it should take MUCH less time to charge the battery and stuff it fuller of electrons.

There is a voltage regulator in the GPS that limits the voltage applied to the battery regardless of the voltage applied to the GPS.

Go into the advanced diagnostics page and you'll find that when the unit is charging from the USB port, the current is limited to 500 ma (the max that a USB port can supply). However when it's charging from the cradle plugged into the car's lighter socket, the current is limited to 1 amp. So the battery should charge faster in the car.

Not Contradictory?

In light of all the details you laid out in the second post as to the differences when charging via USB vs the other two sources, don't you see it as slightly misleading to make the first statement that the battery doesn't know the difference between the charging methods?

Current difference

Actually the voltage is fixed for USB charger. The difference is the current. Normal USB is 500mA, the GPS takes much more than that via its vehicle charger.

I have tried to charge it with the USB and Garmin AC charger...I have let it charge over 6 hours on both and the gps shows a full charge...when on the unit goes from 4 bars to 2 in 10 minutes and then to one bar in approx 5 more minutes and then continuously flashes low battery and won't let you do anything. I upgraded from a 650 to the 750 which I am now sorry I did...seems the 7x0 series has many,many issues and I think that is why they discontinued them..

With my 755t I have an issue where it just won't show as 100% in the diagnostic screen, even after 24 hours of chargining. The max I've seen it go is like 85% or so :S

Try leaving the unit on until it turns itself off. Then place the unit on charge, either USB or AC charger, for at least 8 hours. If the fuel gauge still shows only 2 bars after about 10 minutes, you have a bad battery. Call Garmin support, be nice to them and maybe you can talk them into replacing the unit for free. In any case, don't expect much more than about 3 hours of live our of a charge.

My 760 came from the factory

My 760 came from the factory with a bad battery. You may want to call tech support and see what they think.

My unit was only 6 weeks old when I called so Garmin sent me a new unit to replace the defective one.

It is hard to imagine but some battery problems are not the result of user error.

I don't know what happen to my Garmin streetpilot 330.Before i purchase the 2009 update my battery was working find.Now when i take it off of the charger,it would shut off.I am starting to think that the download has damage my gps.

There isn't much user error when a battery goes bad. These batteries have no memory and Garmin states you can charge them anytime you want as you can with batteries used in cell phones and cameras. I think Garmin may have made a buy from a bad source and that is why there are so many battery issues out there. I have never had a camera or cell phone battery go bad, even after using them for a couple of years.

Definitive info on Li-Ion battery charging

I found the info in the attached link while researching the charging of Li batteries. (Li batteries are an entirely different chemistry from other types. The information is comprehensive and address many of the questions raised in this forum.

http://www.batteryuniversity.com/print-partone-12.htm>

My year and a half old 650

My year and a half old 650 started a similar battery issue probably less than a year after I got it. I use it 95% of the time plugged in but when I went to use it without the plug it didn't last nearly as long as I thought it should have. As others have said, though, since I use the plug most of the time, it hasn't been a huge issue. I'll probably be upgrading soon so it will be less of an issue then.

phxflyboy

Good Info

Definately something to keep in mind.

Contact Garmin

With the issues I mentioned earlier in this post... I contacted Garmin and they have been great.

We only exchanged a couple of emails before I was issued an RMA.

If your battery is not holding a charge technical support an email describing, in detail, the symptoms, what you have tried and the age of your unit.

They are more than wiling to help.

Battery Issue

This is pretty important, and I should probably use a new posting for this, but...

There is also some talk at Garmin about "Thermal Runaway" on some of the Nuvi 200 units. The lithium ion batteries that are in these units are overheating and causing the cases to melt.

There has been talk at Garmin regarding this "Thermal Runaway" and when it happens, Garmin is allowing the owner of the unit that "melted" to choose any GPS (automotive) in the line as a replacement.

These batteries have a definite tendency to overheat, and care must be taken. They should not be left plugged into a car charger that is "always on".

Sorry to rain on anyone's parade.

I take it this is with fairly new units. There have been reports in some of the trade press about problems with Chinese batteries in the past few months. Is there a time frame around the problem that you are aware of?

I have a 350 with great

I have a 350 with great battery life, and I never run it down very much. It stays in the car 24/7 through hot and cold since I've got it over a year ago. It will run for 4+ hours in daytime mode (backlight 100% with no timeout) with the GPS on and tracking. I've loaned it out to people, and don't even give them charger.

Here's a hodgepodge of things to try.

EVERYONE'S DIFFERENT

First, I imagine different unit have different life. My wife's 200W does not last as long. This probably is because the display is bigger and needs more power. Other units have faster CPUs. I've seen new units in stores that do fancy animations. That takes more CPU and power. Finally, different units may have different batteries capacities built-in.

CHARGE RIGHT

All USB is not the same. If you only charge via USB from your computer you are charging at 500mA max, maybe less 100mA if you don't have the drivers installed. If you use the official AC or car charger, it is 1000mA. If you try to recycle one from another accessory it may not work very well.

Now, in theory it should just charge slower but still get to the same amount.

The batteries don't need to be regularly cycled, but the indicator does needs to be trained - it needs to witness the highest level and consider that 100%. Many people skip the instructions to fully charge before using it. After all, you're excited and want to try your new toy!

Train your battery by letting it discharge fully until it won't even turn on. Now, hook it up to the official A/C or car charger, and let it charge until "full". Over night is best. After it's full, let it continue charging for a few hours past full, just in case the indicator is wrong. I recently did this on my cell phone, and it instantly got better life by about 25%.

IS IT REALLY OFF?

My wife's 200W will sometimes get confused about the power state. I don't know if it's because of the nuvi or her car's fault. What usually happens is something like this - she'll turn off the car, and the nuvi will detect this and start powering down. Then she realizes she forgot something, comes back in, powers it up briefly, and then down again. At this point the nuvi then gets confused, and it will remain on all night. The next day the battery will be dead, obviously. This is fine since it's still connected, but if she drives to the grocery store and disconnects she'll see that batteries are low because it hasn't fully charged again.

Garmin replaced my 760

My 760 is out of warranty, but Garmin replaced it when I bitched about the battery not holding a charge for more than 15 minutes. I just got the replacement yesterday (a refurb that looks brand new), so I have yet to see how it holds up.

Just for fun, I submitted a tech support ticket asking how I can buy a battery. Their response was an offer to do a free warranty replacement.

Great

Good for you.....I had two 750's replaced....both seem fine....

--
Bobby....Garmin 2450LM

Just as a follow up.

Just as a follow up. The battery of the replaced unit seems to work better so far, although I haven't really put it to a full test to see how long it lasts. However, as a side benefit I ended up with a unit that has the 2010.10 maps, so I don't have to pony up to upgrade them. I was going to wait until 2011 to update my 2009 maps, but it's nice to have to new ones nevertheless.

Not true, with todays battery technology

I would be interested to know if you leave your gps in the car overnight... Really cold temperatures can severely degrade battery life.

Chances are the Batteries You might have been thinking about are either Nickel-Cadmium (NiCd) Or Nickel-metal hydride (Ni-Mh)

However today's Lithium-ion (Li-Ion)polymer battery technology out performs the above two batteries hands down.

Lithium ion (Li-Ion) advantages:
(a) High performance in cold weather - to 0F - great for winter outdoor use at full power.
(b) Light weight.
(c) Increased life cycles over NiCad and NiMH, so it keeps going past other batteries
(d) more rapid charge times (500 cycles)

Lithium ion (Li-Ion) disadvantages:
(1) less tested than other battery formats - in early stages of development
(2) has a shelf life based on life of battery, not related to charge or charge time
(3) can sometimes erupt or explode in high heat - hot cars, direct sunlight, etc, or sometimes after tampering. a more dangerous battery than the others
(4) permanent damage to battery if stored at too-low discharge level, so be careful and keep these charged well(do not deplete the Li-Ion battery). If you do, do use GPS until battery is at 50% charge to prevent permanent damage.

Batteries and Satellites

My C340 has started having two issues at once: the battery doesn't last long, and it easily loses/can't find the satellites when using the battery.

Are these things likely connected? I assume it's time to buy a new system since the batteries aren't replaceable?

Garmin Battery Relacements

I just "Googled"...Garmin 600 series battery replacemts and came up with a number of companies, such as www.batteryship.com....that offer replacement batteries with instructions and tools, if needed. I noticed replacement batteries for a number of Garmin GPS devices.
My Nuvi 650 is over two years old, with no battery issues so far. However, when the time comes for me to replace the battery it does not sound like rocket science to do the job yourself.

Replaced Battery

I have a Nuvi 760 and after about 11 months the battery needed to be charged more often. I ordered a battery that also came with replacement tools. I think the total with shipping was about 26 dollars and some change. It took about 10 minutes to replace the battery. I saw a video on youtube that showed how easy the battery is to replace.
