We have a Centaur charger (12v/20A) which has been running pretty much continuously for around 10 years. It is charging 1 single battery and one bank of 3. One of the 3 batteries in the bank of 3 suddenly exploded last night without warning.
I'm keen to make sure this has not been caused by a problem with the charger. What tests can be carried out on a Centaur charger to ensure everything is working correctly. I can't remember which distributor we bought it through
