just switched chargers from a shumacher to a black and decker smart charger 15/10/2. it asks what type of battery, a wet, gel, or agm battery. what does this mean? please someone help.

A wet cell battery is battery that has a liquid form of eletrolite. (Just like the battery in most cars.) Most of the "wet" batteries have caps that you can remove to refill the electrolite level with distilled water when boil off has occured. They can be either deep cycle or cranking.

Gel batteries are a sealed form of battery that has the electrolite in a gel form. It is totally enclosed and is "maintenace free". You can not add any thing to the battery as it is sealed. Also it will not spill out unless the battery is ruptured.

AGM or Absorbed Glass Mat batteries are batteries that have the electrolite in a gel form, but it is absorbed into a fiberglass matt and then spiral wrapped with the lead plates in each cell. You can run this battery upside down and it will never leak nor do damage to the plates or cells.

thank you sir.
