BATTERY BEING CHARGED EXPLODED

Postby petesws6 on Wed Dec 29, 2010 1:33 pm

We have a PSC55-12 charger. It is connected into a charging sytem to keep a group series 31 battery from being drained. Upon servicing one of our units with this charger setup, we discovered the battery in pieces, and acid covering everything.
My question is this; Does the charger automatically revert to a floating charge when the battery is at its fully charged state? Is there a seperate controller required? Could a faulty charger be the cause of this?

A faulty charger could do this. Also possible if there is no Smart Charger modules to trip to float.

Exploding usually indicates a high current drain, hooked up backwards with another battery, or a 12V unit connected in parallel to a 24V unit.

We will check through all of your scenarios carefully. I am still not certain in your reply, if the charger reverts to floating charge, stops charging when conditions are met, or if an external controller is needed. Thank you.

An external controller is needed to auto switch to float.

These chargers are being used in equipment that need to be ready to
start at any time so the charging system is essential. Could you tell
me what difference there would be without the multi-step, temperature
compensated regulator in the charging unit you now offer?

The Smart Charge Manager and temperature compensation is essential for batteries that are deep cycled.

Starter batteries don't need such sophistication. There's a plug that changes the set point from about 13.5 Volts to 14.3V. The lower setting is appropriate in most situations. If the batteries are in a cold environment, less than 50F, then the higher setting can be used.

Using the higher setting for an hour every month will extend the life of the batteries somewhat, but it's probably not worth the effort given the cost of the battery.
