Battery disconnects at 70%

[vegard_r]

I have a 3 year old smartcore 7.2V 13,2 Ah battery. The battery indicator has been reset by discharging using the lamp and then charged with the ChargerOne. When the battery reaches around 70 % on the indicator on the battery the CharherOne reads "disconnected". After a few seconds it restarts and then charges again for maybe 10 seconds before it disconnects again. This cycle just goes on.

When i have been using the lamp it wont stay on full power for very long before it dims itself down to the next level, but then stays on for many hours. Any suggestions on what to do?

I would try to discharge the battery till the protection circuit kicks in and try charging back up. You can also use the Charger One to discharge and recharge the battery. Here is the Lupine battery faq page for some more help: https://www.lupine.de/eng/service/faq/batteries

Thanks for your reply!

Sadly i have tried this already and it diddnt work. I have also tried another charger, but the result was the same.

Sounds like the battery might be going bad unfortunately. If you haven't tried it yet you can recalibrate the battery also: https://www.lupinenorthamerica.com/sub- ... p?scID=122
Best of luck getting it fixed!
