Is this sealed or is there a way I can actually check the cell levels? The indicator well in the top is suggesting it needs topping up but I am not sure I can open it without ruining it.
It holds 12v but have noticed it got warm when I last trickle charged it. Hence looking at the indicator well on the battery.
