Good Day! I would like to ask for your opinion if my 12V 100AH VRLA Gel type battery can recover to his charge voltage. Here is the problem everyday I charge my solar battery as usual and I saw it on the SCC that the voltage go to 13.3V or more without load. When the sun go down and no more charging on the battery it drops the voltage to 11.93V everyday at that exact voltage drop. Is it my battery already damage or cannot be recover?..Thanks for the Help
