    Goto Interstate battery They have the battery I think? I'm ording one right now, cost about 12 shipped. its part# lit3165. Its a panasonic vl 1220, at least that is the one in mine. Its supposed to be rechargable. We will have to see. Looks just like the one I have. You will have to solder it in. not too hard.

    Ok so I called Garmin again and someone else told me that the battery isn't rechargable( a diffrent lady at garmin, who checked with ther super), its like a normal Lithium batt in a computer, and when you have regular batts in it then it will feed off them so your not killing your lith. batt. So you need to pull the thing apart, cut seal. which is easy to do and take the board apart (some screws) an solder off the old and solder on the new. I'll let yo uknow how that works when I get it in like 3 weeks.

    My lithium battery is dead, how do I get the 12XL apart. Usually one side is the hinge the other the clip/catch. I don't want to force it open from the wrong side.

You can find the battery here:

To open the case, scrape the sealant in the grove around the unit; then use a flat screwdriver, as wide as possible, that fits in the grove. Place the screwdriver on all sides and different places. Rotate the screwdriver gently until the glue tears and both gps housings can be separated.

To replace the battery you will need to be handy in soldering in tight spaces.

Cut around the outside with a knife. The plastic is only thin in the groove. Seal it back up with plastic glue.

My Garmin GPS 12 XL will not power up. Is that an internal battery problem or is the unit shot as Garmin technicians tell me?

try swapping out the batteries, no harm in opening it up with a screw driver (will void the "warranty" that expired 12 years ago) check if there is an internal battery (usually a coin cell battery like cr 2025 or CR2020) otherwise it is dead and time to get an e-trex 30... great simple little unit with lots more features

I am getting a Memory Battery is Low - how do I recharge or replace teh memory batter. I only load AAA batteries into the equipment?

The memory battery is normally charged by the AA batteries. Leave the batteries in for 5 days. If this doesn't recharge the memory battery then it needs replacing. It's recommended that you send the unit back to Garmin to have it replaced. The memory battery is a Panasonic VL 1220. If you want to attempt changing the battery yourself there's some information on how to do so at

When i open garmin 12xl it gev me vois when i press page bottom this message show me (Memory Battery is Low ) how to solve this

The memory battery is a BTR2032 or a CR2032. This is one of those coin type batteries. To replace it you need to open the case and depending on when your unit was made you will either find a battery hold or the battery will have wires soldered to it.

The batteries are cheap. Usually under $1. Getting someone to change might cost a bit. If this battery goes out then your unit will forget settings and so on and have to reload everything from scratch every time you use it. It will work fine but might take 5-10 minutes (depends on how many sattilites it can see) to get running.

Lost destination after saving it

Sounds like the internal memory battery is run down - it's charged from the AA's. Usually does not recover. Battery (the VL1220) is shown here:

It' easily replaced once the case is open but requires a steady hand with a fine tip soldering iron. Local story started by me here.

Sealing the case up again is very fiddly - hard to make a tidy job with silicone.

Garmin etrex screen too dim to read

I have an older Garmin 12XL and suddenly the screen turned very dark. I tried replacing the batteries and let the GPS rest for a week so the internal lithium battery could re-charge. But that did not work. I just got an email from a friend who had the same problem... it turned out that his unit had changed the screen contrast setting all by its' self.
This may not be the cause of your problem but it's worth trying... go into your "Settings" menu and reset the contrast and see if that cures the problem. Good luck.

Memory Battery Died in my Garmin GPS 12XL...Can I replace it?

Wildstreak, same happened to my GPSMAP 180. Its old and no longer supported by Garmin. I did call them and they gave me the model and number of the battery (mine is a Panasonic) Also advised that units are heat sealed so I am taking mine to a local electdronics shop that also sells Garmin and have them replace the battery.
