so i have read that maintenance free batteries are not quite maintenance free, but close.
an old timer buddy of mine WEARS that you can pop the lid off 90% of the maintenance free batteries out there and refull the depleted water level.
he even showed me his car battery. sure enough the lid was originally glued on. he pried the lid off with a chisel. seems kind of dangerous but anyways there were screw on plastic battery caps/vents underneath the lid just like a lead acid battery has.
so im wondering if this has any real merit. as far as i cam remember maintence free batteries are of a different chemistry than lead acid. i keep thinking of the word calcium but i cant remember why.
im wondering what you guys think about this because my car battery is maintenance free and past its warranty and its getting weaker and weaker starts. im thinking of trying to pop the top and add some water. i was thinking that i have nothing to lose but my time, which i dont like to waste.
should i bother giving it a shot?
