Now I must say a truck battery at least in any truck that uses two(or more) batteries life is much shorter. Typical for me 2-4 years.
Golf cart chargers? what do they do in terms of voltage and three stage or not charging? I realize most of us are not setting up a 36 volt system so it is not practical to use a golf cart charger. However still have to wonder as they do seem to work well for golf carts.
Most golf carts have flooded lead acid batteries and they can take a bulk charge from a standard alt in a house bank set up. Chargers are pretty much the same bulk charge but have a float mode to keep the charge topped off. Some chargers reduce the charging as the voltage comes up. Some have a desulfation mode. I won't get into that.
