Default Another CAI 302 Maitenance question

Hey T8 and maybe Dave Kinsell
I've removed my 302 from my plane for the winter.
I understand I have to power it up once in awhile to keep the GPS engine charged.
How often and for how long should I power it up?
TIA

I expect if it was powered for three hours three times over the winter,
that would be conservative. It's a tiny rechargeable battery you're
recharging, so it will eventually wear out even with frequent recharging.

I have more faith in the PF logger and use that, with the 302 left in
the panel just for the variometer. Last I checked, the date was still
correct.

It's just a guess, but that sounds like a good guess.

If the 302 is already out of the glider, it would be a good time to replace the GPS engine. Send it to Gary Kammerer.
..... Caution! Attenzione! Vorsicht! PrecauciĆ³n!
This involves spending money, which glider pilots are famous for avoiding.

Thanks for the responses.

Craggy keeps bugging me to get a S 100 but my two 302's still work great and seem to suit my flying style.
I had Gary Kammerer replace the GPS engine in one of them back in 2015, the other ones still seems OK with a good date lock.
Cheers
