Thread: How To Replace The Internal Battery on A Garmin Nuvi GPS

Thanks for the great tutorial for the Nuvi 765T.
However, that model is probably the easiest one to change of all the Garmin models.
The 600 series is far more difficult to change and personally I would not attempt it since it is buried deep in the unit and you can easily damage one of the ribbon cable to get to it.

If you do want to change your battery, I suggest you visit newpower99.com.
In the search box type in Garmin Nuvi and your model #. It will bring you to the battery replacement page.
Click on the battery, the next page will give you an option to view a video on youtube. The video's are well done.
I don't think videos are available for the newer series like the 2x & 3X, but many are available for older units.
Here is the link for the Nuvi 660.

They also sell the batteries and tools there but you can find them on Ebay much cheaper, however, Ebay is always a gamble.
If Newpower 99 doesn't have a video for your model, you can always try a Google search for a video on your model.

Another point worth mentioning is GET THE CORRECT BATTERY. The older 600 series has a battery life of 7 hrs and uses a
1500 mAH battery, this battery has a two pin connector. Since the 765T only has a battery life of 3 hrs with a 1250 mAH,
you may be inclined to replace it with the 1500 mAH, it won't work since the 1250 battery has a three pin battery connector.

For those of you that are mechanically challenged, below is a link for a reputable GPS repair shop that replaces batteries and much more.
