Overcharging or defective battery. They will also crake in freezing temperatures if the battery has lost it's charge.
No, replace the battery.
There is a crack in the battery case. Replace the battery.
Yes it can.
Is there no one to answer this?
If the battery were not securely fastened down Any speed could possibly crack the battery. If the battery is securely fastened down it would depend on where the vehicle was hit in the accident.
Yes as long as it is just a surface crack and no battery electrolyte is escaping.
No. Freezing a battery will damage it. have you tested it? The worst environment for any battery is COLD. That is why there are so many problems with car batteries in the Winter. If the electrolyte in the battery freezes, it will usually expand and crack the battery case or distort the plates in the battery
I would guess if a battery has a water to acid ratio high enough to freeze that it would not hold a charge well. Be sure the case did not crack.
It's really not worth fixing even if you could. It's better to just buy a new one.
there is No battery for the E93 Hardtop its connected to that car battery... sorry to say E93 are having hard top Problems and they are not cheap I have also seen them leak from the center crack And "Ooo Boy they arnt fun"
Crack or hole in the battery case or it is being overcharged by a defective voltage regulator.
No, a car battery does not have mercury in it. It would be very dangerous to have mercury in a car battery.
