What would cause a battery to become swollen in the middle (no offense meant to pregnant women or beer lovers)? I know that distorted lead plates caused this, but I need to know how to avoid a reoccurance with my new battery. There also was a jagged hole in the side of the plastic case, but I couldn't see the corner of a lead plate sticking out.
The previous (original) owner used to replace the battery every two years, while this one lasted for four years. I use the car only once a week, though.
I noticed that the paint was stripped below and around the battery when I bought the car, so I'm guessing that a previous battery leaked too.
In addition, the battery would always be wet on top. Am I adding too much distilled water?
Since it's winter and I use the car only once a week, can I keep my (just bought) battery trickle charger permanently connected? Do I have to leave the hood open as the instructions state?
Any suggestions would be appreciated.
