Help needed: I have a 99 E825 2dr. I bought it with aquamarine deep cycle wet batteries in it. 31 class. The display never worked so I never knew if it needed charging. The guy I bought it from told me the display never worked for him as well. I just drove it and plugged it in after use. Eventually after 6 months the cart died. Batteries were toast. Here lies the question…  
What batteries and class do I need? I’m not looking to do lithium swap. I’ve read to many posts stating that some carts are specific to battery class for chargers. How do I know what my charger is programmed to for what battery. I’m new to gem and think I am in over my head at this point. Any help would be greatly appreciated.
