Solar group,
I have a 440 ah - 48 volt battery bank which consists of (8) 12 v batteries
in (2) strings. I have one battery that consistantly reads low compared to the rest.
I have tried equalizing using my system - bringing the bank up to 62 volts for 1.5 hours.
Don't want to push it. This one battery has a cell that was reading 1.26 SG when the
rest were 1.275 to 1.28. To add insult to injury - I happened to overfill that cell when
watering them and now it's 1.23 campared to 1.27. These batteries are 15 months old,
but they sat for 13 months on a solar charger in parrallel.
1) Now I could remove this battery and get it warrantied?
2) Change out the whole bank?
3) Change out both banks?
4) Leave it alone and watch it for a while?
Your thoughts are appreciated!
