Does A Agm Battery Need A Special Charger. Chargers designed for long term charging of flooded cell or AGM batteries will frequently have a remote temperature sensor battery charging voltage is temperature sensitive and 2-3 charging stages--with the last stage a float voltage setting backs charging voltage back to around 127-136 volts to prevent boiling a battery dry andor an automatic or manual equalize setting which can be turned offadjusted for AGMsealed batteries. AGM batteries do NOT require a special charger.
AGM batteries need a particular type of charging system. I have ruined an Odyssey battery by using a normal charger several times. These units are specifically designed to charge and maintain 12-volt OPTIMA batteries as well as all other 12-volt AGM batteries.
Basically the battery swelled up like a balloon although it still works but it doesnt fit in my battery tray anymore You need one of those smart-charger things that is specifically designed to work with AGM or deep-cycle batteries.
A specific charger is not required for AGM batteries but a special charging mechanism is required. Most devices available on todays market are of the inverter type. A regular ol constant voltage charger such as youd buy at the local auto parts store feeds out power at. These units are specifically designed to charge and maintain 12-volt OPTIMA batteries as well as all other 12-volt AGM batteries.
