Golf Cart Batteries Not Charging

[GLM]

My 48v Bad Boy is not charging. It runs fine and the battery level on the das shows 3/4 charger.
The batteries are only 6 months old. I did have to add water to all batteries yesterday but they are not charging. This picture is what the charger is showing. Normally goes from 1 red light to all red lights then the green light (with all red lights off) indicating full charge.
Is it a battery or charger problem?

Don’t know if this will help, but found the charger manual. I just had to replace my charger and I didn’t realize they cost a ton. Good luck

Check the overall voltage to see what it is. If it has gotten to low it may not activate the charger. If you have 8 - 6 volt batteries and they are low you can charge them in pairs 12v with a 12volt charger. Charge each pair for about 15 to 20 min then try your regular charger.
Good Luck

I had to do the same thing one time. I also had a battery with a bad cell & it would not charge up enough to get the charger going.
