Google should be the best friend and best place to find most answers.

Anyone know were I can obtain a memory battery for Garmin GPS III, I believe
it is a rechargeable lithium, VR1220



UK if possible

If you can't find it with Google or on eBay then it probably doesn't exist
for sale anywhere. Maybe time to upgrade to a newer gps?

Please not that while that lists a *stock #* of VR-1220, the battery
type is listed as CR-1220. Which is a very common 3V lithium button cell
that is not (to my knowledge) rechargable. Swap one for the other at
your own risk.

Hello,

it is not a good idea to use rechargeable cells for memory batteries. If
you don't recharge often enough, you will loose memory contents. The
current used by the memory is so low that a primary cell may last up to
ten years, rechargeable cells may fail within about five years. Buy
applying an external voltage it is even possible to change the battery
without loosing the memory content.

Garmin did use the VR1220 on (if I recall correctly) the II+ and III+
series, while the II and III used non-rechargeable (*).

The II+ was subject to an out-of-warranty-period-but-covered-by
warranty service to rectify an issue with the charging circuit on
quite a number of them, including mine. Unfortunately - and it may
have been Garmin's suggested fix - the local service agent replaced
the VR1220 with a CR2032 and of course it wasn't long before the unit
was again failing. This time though the warranty extension wasn't
offered, so it sat derelict.

Later I opened it up and found the CR2032 (curse, swear). So I
replaced it and the II+ came to life again. Three months later with
only intermittent use, the battery had died again, so I'd suggest the
drain was significant and there is no way a primary was going to last
ten years.

I'd suggest to the O/P that he opens his unit and verifies the battery
type fitted. As long as the service life it had provided was
acceptable, renew with the same type.

(*) I may have these the wrong way around, but the Plus and non-Plus
used the different types.

Do people with these old GPSs find they are still useful? My early GPS-II+
(before the spec upgrade) works fine except for an illegible screen. It
flickers the few pixels that are left and even sometimes has a bright blue
horizontal line. (Baffling since I thought these old grey-scale displays had
no colour capability!) I can still use it for accumulating tracks but not
for navigation.

I have a Rockwell/Conexant Jupiter GPSr which I use as a front-end for
a time/frequency reference system. I also have a nuvi 760 for car nav
use.

My GPSII+ was used as a timekeeping system front-end, and also serves
as a real-time NMEA sentence source for software development. In that
role there is little point in replacing it (that is, aside from the
memory battery issue.)

I'm not sure to what extent others have a current nav use for these
oldies.
