I finally got up enough nerve to replace the battery on my 765T! I followed the instruction video over youtube.com, it was a snap, and surprise of surprises, it works! I also have to do the same thing to a 760, should be no problem. Much, much cheaper than sending it off to Garmin, and it's as good as new.
Where did you get your battery?
I'll be doing the same to my c340 next week, just need to pick up a battery first. Glad to hear that it went well for you!
Is the battery kit really necessary? What tools are you getting? I probably have all of the tools I need, just wondering what all you may have used.

From what I've read, all you really need is the proper torx driver and a plastic pry bar. Do not use a metal blade or screwdriver to try to pry the two halves apart since that almost guarantees exterior damage.
Here's a good source for battery plus tools:
One of the major benefits these places offer is selling you a kit that not only contains the proper battery, but also the proper tools. If you do a lot of work on small electronic devices, you might have a set of plastic case tools. But it seems every manufacturer uses a different sized torx bit, or puts a phillips or pozi-drive down a narrow hole so a special tool is needed.
particularly with the aid of videos (and a pie pan or other container to put parts in as you remove them), the job is pretty easy.
Here's a link to the battery replacement video:
They have a link to the store where you get the complete kit for $23.95.
Ebay has batteries for $8.75 and more ...
from e-bay.com, $10.71. Works great too....so far, check it out. Just installed another in a Garmin Volvo Nuvi 760. Re-charging it now.
I bought the kit on only one of them so I could get hold of the tool set, Smart I thought. I now use the tools with additional batteries. The only issue is that the battery alone does not have the double sided tape to adhere the battery to the case, so, either pick up some double sided tape or use the one on the battery you replace.
"top1ratedseller" VERY fast delivery!!
I think it is...It has all you need to get the job done in about 5 minutes...youtube video very helpful.
I have a StreetPilot, but did a quick search for a video for it. Should be a simple process.
video, and you shouldn't have much difficulty. It does look a bit more involved than the others...but still less costly than sending away...good luck!
This thread was good information on how to change the battery at a good price.
I often find my nuvi 750's battery is dead, but on the other hand I almost always use it with the car power adapter.
I am not sure how important it is to have a good working battery?
I have also read that what kills a Li-Ion battery is heat. Thus, in a laptop if the CPU temp gets high and the disk temp gets high, then the battery is being exposed to heat. With the GPS, it is probably from leaving the GPS in the car on a hot summer day. (http://batterycare.net/en/faq.html)
At work I do bit of soldering with circuit boards, so I've got the tools and some experience to do the job. Hmm..., maybe I could make some spare change on the side
Typically I will use my GPS without a power cord on my way back to my car (depending on how far away I had to park, maybe a block or so in NYC when I'm there) so it is nice to have a battery that lasts more than 15 minutes. Currently I might get 10 seconds to a few minutes, depending on its mood. Just turning off the car will cause it to shut off immediately.
You are certainly correct, heat is terrible for these units! I never leave it in the car when I'm not there, but when driving it can get quite hot while mounted on the windshield for hours at a time. I'm sure 4 years worth of constant driving (use it almost daily) is enough to do it in. I hope the new battery will last as long

That's cool. I never thought about using my GPS to find where I parked my car.
when I knew I had to do something! Searched youtube.com, found out how to replace the battery, and hunted for a good battery at a fair price. The thing I did know was that sending it to Garmin, would cost me at least 75.00 incl shipping and insurance, I chose not to do that..now i have two GPS's with new life in them...good luck!

the video, those came with my first battery order, I thought that I would order just the battery alone, since I now have the tools I need.
are you going to give 'er a try and attempt to replace the battey yourself?
It was a breeze! Kit came with every tool required and more.
I believe some Nuvis will automatically store the location once they are removed from the windshield mount for this purpose. With the StreetPilot I just manually save it, not a big deal for me. I've realized how pathetic I am with not remembering where I park, I'd probably have trouble if there is just one other car in the lot...
I'll replace the battery at work, shouldn't be more than a 5-10 minute job. I've taken my GPS apart before just to see what was in it, looks fairly simple to switch out.
My battery was really stuck to the case with a lot of glue. Had I not watched the video, I would have thought I was doing something wrong trying to pry the battery away from the case. So, if it seems to REALLY be stuck to the case, give it a REALLY GOOD PRY and it will give. Works great after the battery replacement.
you will have no problems...
At the Super Bowl as well as the Pro Bowl, I was forced to park about a half mile or so from the stadium. I wouldn't have been able to find my car as quickly if I hadn't changed my nuvi 780 battery just prior to those two events. What a life saver that was!
My battery was shipped in from Singapore, and just arrived today. I did run into a bit of trouble on the last speaker wire, as the part I was soldering to fell off of the speaker. Fortunately there was another place to solder the wire to, and it works great now! Seems weird to see a full charge last longer than a minute or two
On a side note, my GPS chip resembles a nicely toasted marshmallow from being on the windshield for hours at a time in the hot sun. If I start to have problems with satellite acquisition I know what my next repair will be!
I got mine through Amazon.com
I've got a wide assortment of tools, including tiny torx drivers. Still, when I had to do the batteries in our Nuvis, I got kits that included the tools so I'd be sure I had whatever weird bit that particular manufacturer decided to use for that model.
The case opening tools are useful as well, and multiple sets are good to have.
Take your time, use something like a pie tin to hold the small parts you take out, and you shouldn't have a problem.
my c550 is still going strong
I thought my 760 needed a battery. I was mistaken. I opened the unit & disconnected the battery. I wanted to see what I would be getting into. When I reconnected the battery, it acted like it was almost new. I've gotten at leat an extra year out of the battery since then. I suspect I'll still have to replace it soon. Thanks for the suggestions on battery suppliers.
Now that's interesting. My 750 has the original battery that seems to be on its last legs but I've avoided replacing the battery since the 750 is just a backup for me--and it's used 99.44% of the time plugged into the car's cigarette lighter.
But you make me think I could be as lucky as you with your 760. It's worth a try. In any event, like you I'll see how the disassembly/reassembly goes as a trial run before going out and buying the battery.
Thanks for the tip.
Good info. I now have the confidence to do the job..thanks
ANYONE can!! Besides, it makes you feel good!!
buy the replacement battery and replace it at the same time. To take the time to open the GPS, without replacing it is double work. If the battery is having problems, that's the time to do it!
Thanks. I should look into that. My battery is constantly "low"
and I wondered why, but, I hate double work...and the batteries are so reasonable...why not? You'll like the GPS even more, it'll be like new.
I'm retired--time is not an issue

too! Fun isn't it?
Not sure how the Nuvi process compares to that of a StreetPilot, but it wasn't bad. Just a bit of soldering, and then plug in the connector.
I've looked at the Nuvis, not impressed. Would rather keep my c340 forever than use what is currently out there.
Me...too! Fun isn't it?
Well, I've done my trial run. I had a set of drivers so the big issue was finding something in the house that would be my plastic pry bar.
It's now back together and I'm charging the old battery again. If it's still weak, I'll go ahead and order a 750 replacement battery then see if I can remember what I did today and put in the new one.
Replacement of the battery in the 760 was a snap - and I'm not real dexterous.
I'd have to agree as far as keeping an older model. I'll take my old 760 over the newer models any day. When I managed to "lose" my old 760 I replaced it with the same model. I could have purchased any GPS I wanted but preferred to stick with the 760 rather than get one of the new and "improved" models.
Have noticed my 5-year old Garmin 660 not showing 100% charge... So ordered a 36100019-02 battery... found it with tools on Ebay.... for 15.99 with free shipping....... After finding the video showing how to do it!!! ! It's a higher current replacement than the original...
I should have some 'interesting' comparisons of the 660 vs. 2011 Ford Escape Nav package in a few days..........
as long as it works, keep it.
The Nuvi's (excepting the 300 series)are very simple, no soldering at all!
Good find. I think my battery might be getting weak and had only briefly considered what I would do when it goes out.
then replace the battery. Way cheaper to replace one than to replace the whole unit. Especially if you bought a lifetime map subscription.
That's even easier! No excuse not to change it.
Thanks, a good place to buy my next battery..
Totally worth replacing the battery on the 7x0/7x5 series units (at least). They're easy to open and battery replacement requires no soldering.
I should have listened to you. My disconnect/reconnect didn't do anything. I've now ordered a $8.75 battery from eBay with free S&H. Since I found something at home to use as a plastic pry tool, I just needed the battery.
I need to replace the battery in my Nuvi 260 when I visit http://www.batteryship.com/ it shows a two pin and a three pin connector, how do I know the one inside my unit if I don't have the tools to open it?
Is there a way to know based on the serial number?
E-bay! look at this....
