Battery Fluid Levels

Tony, is it both batteries or only one?

Both batteries

Hi Tony, I have that problem, i think its mainly because i run my fridge all the time , its seems to be the high discharge rate and then thehighcharge rate that follows. Michael

Tony,

Thats abnormal. Just wondering whether you're alternator's regulator is misbehaving and your voltage is too high. If you have a multimeter, check what the volatge is while you're running the vehicle. Shouldn't be much above 14.2 volts.

I live up the pointy end of australia (it's hotter than where most folk live) and run a fridge permanently in my vehicle.

I usually top up the water in the aux battery every 5-7 weeks and every 2-3 months for the starter battery. If your doing it every couple of weeks then there may be a problem.

Tony, only two reasons why batteries use water:
1. Charge rate too high,
2. Battery about to fail.
