Hey, I was around my mates house the other day and he got me to have a look at his battery on his ke70. The battery was very swollen and it was making a hissing nosie and leaking a little bit of fluid. We took a reading with a multi meter and the battery was reading 16.7 volts. is this due to the alternator overcharging his battery? (he currently isn't driving the car due to he doesn't want to blow up the battery, which is brand new)
