Lithium Memory Backup Battery

 

I just pulled out my antique but-still-working-great Garmin GPS 12 which is great for field work. However, I'm getting a message that says my lithium memory backup battery (no wonder, after close to 10 years) is low. As the unit is sealed and the manual does not address changing this battery, sending it back to Garmin is the last resort. Anyone have any experience with this?

Am not that familiar with

Am not that familiar with your GPS 12 baby. Doesn't it get plugged in on the car's power socket like what we guys have? Is yours like the handheld CB radios ?

From the Garmin website ...

"If you own an 8-channel GPS receiver unit, a marine GPS unit or chartplotter, or an aviation handheld, your unit has a non-rechargeable memory battery. You will also need to send your unit to Garmin for replacement under our flat-rate repair program. In this case, please e-mail Garmin using the above link or call Garmin Product Support at 1-800-800-1020 to arrange for an RMA number to be issued for the return of your unit."

GPS 12

It's driven by 4xAA batteries and is used for land navigation in the boonies.

Memory backup battery replacement

The GPS 12 is for land nav, is a 12-channel, is not a marine unit, chartplotter or an avaiation handheld. I guess I'll have to call the number and see what they have to say.

Thanks for the try.

If I remember right (and I think I do, but it has been a while) that battery is actually RECHARGED AUTOMATICALLY by the AA batteries that power the unit. Unless the lithium battery is actually DEFECTIVE at this point, it will recharge itself (it actually takes a few hours or days, I can't remember which.)
