Garmin OEM batteries

When you say you charged these two batteries for six hours, is that using a USB charger or a cigarette lighter socket using the Garmin power cord? Six hours may not be long enough to charge a nuvi battery via USB. I assume you have things configured so that you know the power source doesn't go to sleep or turn off after a period of inactivity.

I buy from:

Others have bought from:

From all I've heard, these batteries result in nuvi operations no different than from the OEM battery when the nuvi was first purchased.

I did find some Cameron Sino batteries on Amazon and some user reviews are less than desired while other online reviews are quite good. You may have just gotten two batteries from flawed stock, old or improperly stored batteries, etc.

For the majority of nuvi models that are "not user-replaceable" in Garmin-Speak, I think it'd be nearly impossible to buy a Garmin-branded battery.

Both batteries were charged for 6 hours via AC charger.

I agree with CraigW. It is also possible the nuvi is not really connected (or intermittently connected) to 12 volts in the car.

The batteries were not charged with a DC car Charger. The Nuvi was charged with an AC charger that functions normally when the original Garmin battery is installed.

Six hours should have been enough time to fully charge a dead battery. Some folks seem to think that any problem is the result of the person operating the on/off switch. I haven't had any personal experience with this company but I've heard nothing but bad reports from a lot of Chinese companies. Try to get your money back and don't buy anything else from them.

I replaced the battery in my 750 a couple of years ago with an after-market replacement from Amazon. I've had good service from it. You might order your next battery through them.

I replaced the original battery in my Nuvi 750 with a Cameron Sino after-market battery and it also has performed well.

However, one of their batteries in my 2460LMT,as described above, does not "work".

I want to thank CraigW for providing the batteryship.com website. They provided the battery and tools I need at a reasonable price, much cheaper than newpower99.

I like to walk around with my nuvi 350, while on vacation found it wouldn't hold a charge after a 5 hour drive. Plugged the gps into wall charger overnight, it said 100% charged, about 5 minutes later the display shut off. When I restarted unit charge was 1 bar. I plan to replace the battery as my 350 has served me well.

Garmin does not make battery. So, when you buy a replacement battery from a reputable replacement battery outlet, it is likely the same battery from Garmin except the label.

If you replace the battery yourself, make sure to double, triple check your work.

Communication with both Batteryship and Newpower99 verified that both provide the same battery (361-00051-02)

This seems to indicate the problem is with my installation of the battery or a hardware/software problem within the unit.

I have successfully replaced batteries previously, but I may have missed something.

Any software/hardware suggestions?

Since most component batteries (Garmin, cell phones, etc) are NiCad (Nickle-cadium) I think, they need to be fully discharged before recharging. Not always convenient when traveling but a good practice to make your batteries last as long as possible.

This Garmin Unit (nuvi 2460LMT)uses a lithium-polymer battery. I believe most new Garmin units use this type battery!

Correct. Today's Garmin batteries are LIPO as are most (all?) currently-used rectangular-shaped rechargeable batteries used in small electronic devices. LIPO is a type of lithium ion rechargeable battery.

In the old days, NiCads were used but more recently, NiCads had been replaced by NiMH batteries.

The old issue with memory effect issues shortening battery life or full-charge issues were seen on the old NiCads.

I have 2 replacement batteries and both are Li-Ion, not Ni-Cad.

This is bad advice for all battery types of interest. Yes, there are come combinations of type and history for which an occasional deep discharge is helpful, but there are many types for which each deep discharge is appreciably harmful--and people going out of their way to get a full discharge every time are misguided.

Speaking of misguiding--there is precious little use of NiCd batteries in current new production equipment. Famously, airplane "last-ditch" batteries on many models continue to be NiCd (but not the 787...), and there are probably other examples, but I'd be really surprised if even one percent of the home devices readers of this forum have purchased in the last five years have them. They have considerably lower energy density than any of the lithium types, they pose a nasty disposal problem (think of the word Cadmium in the name--and nickel is not all that nice either), and are not otherwise competitive. NiMH and some lithium types are both far more common in current new production devices.

Thanks for the update...

louitop,

I am having the same problem you described in your email. I replaced the battery in my 2460LMT and the battery does not seem to charge with home AC or with car charger.

It acts as though the battery thermistor isn't connected properly. Charger thinks it is over-temperature and does send current to the battery.

SW version is 3.5, and Firmware is 2.89

Were you able to fix your problem? If so, what did you find?
