Hello,
i have two JA-803450P batteries, one from EduArdu and one from Lime2 home server.
They stayed long time unused.
Lately i needed EduArdu as remote control and tried to charge one of them.
However, they do not seem to charge in 1-2h at all.
The measured voltage is v. v. low: 0.1V
The spec https://www.olimex.com/Products/Power-Supply/Lipo-battery/BATTERY-LIPO1400mAh/resources/JA803450-Spec-Data-Sheet--J-A.pdf
mentions in §8.7 and §8.8 "charging from 0" respectively after long time.
Is there a way to re-charge them using EduArdu or Lime2 or is special gear required?
Otherwise, they are due for recycling ...
Thanks in advance.
They need more time. Leave them connected for 24h and check again. If the voltage stays 0.1V after 24h of charging they are probably very dead.
