A golf cart battery and your automotive battery are two totally different styles of battery. The golf cart battery is deep cycle, it is meant to be discharged, an automotive battery is a starting battery, and as stated, used for a few seconds and the car system takes over. You cant compare the two. Florida heat does kill batteries no matter what type they are. 7 years out of a golf cart battery or an automotive battery is not the norm, no matter how you use it or charge it.
The biggest killer of a golf cart battery is " depth of discharge". When a battery is new and has full capacity, a 20 mile trip may only be a 50 percent discharge, but at 3 years that same 20 mile trip could equal 80 percent discharge. A 48 volt pack, at full discharge is 42 volts underload, the problem is the cart will run normal so people just keep driving, thus damaging the batteries.
I'm not sure what everyones experience is or how many golf cars a day everyone works on, but I see it everyday and hear every which way on how to charge a set of batteries. I can only give out info of what I know has worked for too many years to count, and the info can be taken for what its worth. Doesn't hurt my feelings if its not followed.
