Has anybody any experience of changing this battery? (presumably internal
battery)
I now have the low memory battery warning which would suggest it will stop
working shortly.

The internal battery went the same way on my GPSII+. It is a lithium battery
(non rechargeable) approx 10mm in diameter and 2 mm thick WITH TAGS - not
just a watch battery. I put main batteries in the unit then cut out the
original and soldered the new one to the tags of the original. The message
has now gone and I did not lose the memory.
I did not realise the memory battery was non-rechargeable and now ALWAYS
leave batteries in the unit when not in use.

Thanks for advice. I contacted Garmin who inform me that the memory battery
is a rechargeable lithium battery. This should recharge with a new set of
alkaline batteries fitted within 10 hours when switched on and 5-7 days when
switched off and then last 2-3 months with out batteries fitted.

Failing that return to Garmin.
Thanks again......

Hi

Yesterday when I turn on my GPS (Garmin 48) I got the message that said
internal battery low. The gps had been whithout battery for a while. I had
to replace the batteries, and when I turn it on again this morning I got no
message. I called the dealer and they told me that the internal battery is a
rechargeable battery, and that it takes about 10 days to charge it if the
gps is switched off, and about 10 hours if it is turned on. In the manual it
says that the internal battery is a lithium battery, but since I didn't got
any message today I guess they are right. They also told me that they have
had a couple hundred phonecalls about the same. My gps48 is from 1999.
