Hello all..
2 years ago I fitted a solar panel to my shed, charge controller and battery. It has all been working fine, but recently it has been losing it's charge very quickly and the charge controller kicks in and turns the lights off.
The battery charges up to 13.7V but drops to 12.1V very quickly with only a small amount of power being used.
It is not a sealed battery, however I do not know how to determine if it needs topping up with distilled water? Also, what level do I fill it up to and also is this going to help with the discharge problem or is it beyond repair? I have not topped it up since fitting it.
I have attached a photo showing inside the battery, no fluid is visible.
