Hi all. We have two lead acid cheap fleabay batteries. 130amp each.
Our panels are 700w total but with the rain and panels flat, we’re only producing between 100 and 250w a day.
Not having any other form of energy to charge the batteries they inevitably ended up being discharged quite a few times.
I just wanted you guys to confirm (or not) if these batteries are now busted. I’m attaching the voltage trends and basically when the voltage drops from roughly 12 to roughly 10v, nothing has been plugged in. It’s always only lights around 7pm and then phones at the very end of the night. But the surge between 12v and 10v is not being caused by extra load on our side. I.e. we’re not using more power when that voltage drop happens.
Also, would this be covered by the batterie’s warranty?
Thank you!!
