Problem with Akku in OSTC plus

[Navigare]

Good day

I have a problem with akku in OSTC plus. Bought new device in Boot this year. about 20-30 dives. Recently after first dive the percentage of battery was 26%. During next dive (it was recreation dive) the computer went off after I came out from water. Tried to switch on - akku indicated 0%. Tried to charge - no charging.
Till end of vacation dove with battery instead of akku.

At home I bought Saft LS 14500 LiSOCl2 akku. Computer does not start. Tried to charge it. Charging was done inside the computer. Computer does not start. Measured voltage of akku - multimeter show 3,68V. Tried to charge akku in external charger. Computer does not switch on.

When I put normal AA battery inside computer starts up.

Updated firmware from 2.99 to 3.01 - no effect

Anybody had similar issues?

This is not a rechargeable battery...

Do not try to recharge this battery.

Trust me: Remove this battery immediately from the computer!

Please contact us, it seems your original (rechargeable) battery is defective: info@heinrichsweikamp.com

Dear Matthias

Thanks for answer

I did not expect that I was so stupid. You are absolutely right -- it is battery. I confused because when I ordered it, there was in description 2600 mAh. Normally this refer to capacity of akku, I never saw such info for the batteries.

The only question remain open -- why the computer did not start when I first time inserted the battery. Up to now I can measure some 3.6-3.7 V.

I will send email to support as per your advice

best regards
