    How To Replace The Internal Battery on A Garmin Nuvi GPS

    IMG 1095preview1preview4preview2What do you do when your Garmin nuvi GPS will no longer hold a charge, and the internal battery doesn't last more than a few minutes? You could just live with it and always use the vehicle power adapter. Or you could send it in to Garmin for repair.
    There's another option: It turns out that replacing the internal battery is an easy task that takes just a few minutes to complete. Here's everything you need to know to successfully replace the internal rechargeable battery, complete with step-by-step instruction.

    Important Note: This is an easy procedure, but doing so may void your warranty. we assume no liability expressed or implied for any damage to your device.

    Figure 1: Garmin nuvi Battery Replacement Kit
    Battery replacement kits are available from various vendors. I bought this nuvi 700 series replacement kit on Amazon. Most battery replacement kits come with all the tools you'll need to perform the battery switch, pictured above.

    The basic process for replacing the battery is pretty simple:
    1. Open the back of the GPS
    2. Remove the old battery
    3. Install the new battery
    4. Replace the back cover
    Let's get started.

    The first step in replacing the internal battery is removing the two small hex screws shown located on the rear of the case.
    Different Garmin models use different screw types. The 7x5T models use a small hex type screw.

    Using the hex screwdriver included in the battery kit, remove the two screws on the back of the device.

    Set the two screws aside. You'll need them again when we put the nuvi back together.

    The battery replacement kit includes a plastic case puller tool, shown above. You can also buy these separately. Insert the tool into the groove between the back of the case, as shown above, and pull up on the tool until the back of the case separates from the top.

    Figure 7: Remove the Back of the Case
    Use the case puller tool to pry apart the rear of the case, working your way around the case until the back is fully separated.

    Once you've managed to pry off the back of the case using the case puller tool, gently open the nuvi up as shown above.

    Figure 9: Garmin nuvi, Opened
    You'll notice two cables that connect the back of the case to the rest of the nuvi: a speaker cable, and the battery cable. Carefully disconnect both cables.

    Now that the speaker and battery cables have been unplugged, there's enough room to fully remove the back of the case.

    Figure 11: Remove the Original Garmin Battery
    The rechargeable battery is held in place with some double-sided sticky tape. Simply pull the battery off the back of the case to remove it.
    Don't discard it yet -- we need to save the double-sided tape and re-use it on the new replacement battery.

    Peel off the double-sided tape from Garmin's original battery.

    Apply the tape to the top of the new battery.

    Put the new replacement battery into the back of the case, and give it a firm press to let the double-sided tape bond to the case.

    Figure 16: Re-Connect the Wires
    Plug the speaker and battery connectors back into the GPS (the wires are short, so you'll need to hold the case in a half-closed position to be able to connect the wires).

    Figure 17: Re-Assemble nuvi Case
    With the new battery successfully installed, the nuvi is ready to be re-assembled. Start at the top of the cass (the side with the power switch), and firmly press down around the edges of the case to snap it back together.

    Figure 18: Re-Assemble Case
    Take care that no wires are sticking out of the base of the GPS when re-assembling it.

    Figure 19: Tighten Screws
    Secure the GPS back together again by putting the two hex screws on the back of the case back together. The screws should be tight, but not over-tightened.
    That's it!
    You have to navigate to get to the good.

    Default Battery upgrade

    What kind of performance do you get out of an aftermarket LiPo battery???

    A followup to that great how to would be a report on battery life after the replacement.

    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.

    In no way am I endorsing the two links I posted, I merely want to suggest sites that forum members can benefit by.
