Adding water to battery cells
thats a nono. not worth your safety for $100 battery. replace and be done with it. properly dispose of the battery
Most batteries these days are sealed, yours looks like a sealed battery.
Yup, it's sealed. Maintenance free. If you know or suspect that it's low on water replace the battery and have the charging system tested. A battery that is being overcharged will gas and lose water. HTH. -Jim
