Have a 2006 Club Car with a new 48 volt battery system, how long should the charge last before recharging & should I charge it overnight in my garage?

Check the Chases cable

do these batteries run in series or parallel ?

the car as a wire connected to the chassis and he is descharging the battery. you have to go to a car electrician and look wall the cables to see where he is not isolated.

disconnect the battery and leave overnight whilst its on charge then try it again tomorry ,did you just unplug a code reader if so then this shouldnt cause any problems

if the batteries are 4+ years old its most likely low voltage .also check solenoid.Club car is very good and not many problems with them.most likely it is minor.

your battery could have a dead cell and still register 12 volts when not running,, if your getting 13.67 volts on the posts with the car running, the alt is fine,, but the battery is faulty,, take it and have it load checked, that way you can be sure it has the amperage that its supposed to have,

From what you're saying here, I believe that you simply have a bad battery. Most batteries only last 5 years, much less if they're left to sit in storage periodically. You really should charge the battery overnight and do a load test on it the next day. The person(s) you spoke to at BMW were probably sales staff and not actual technicians. Costco has very good batteries at reasonable prices.

you definitely need a new battery. replace it, and have the charging system checked when you do. If you do it yourself, use a volt meter to make sure that your battery is holding at least 14 volts when the car is running. anything less, and your alternator is bad. I dont think your alternator would be bad, though. your whole engine and transmission is electronically controlled and runs off of the power generated by the alternator. the battery is primarily there to start the car. without the power generated form the alternator, all of these things start drawing power from the battery. and since the battery cant recharge itself, it will eventually die, and so will your car. so, my guess is your battery just went bad, and your charging system is good. have it checked just to be on the safe side though.

It is the Alternator. The Battery will Charge But drains while Driving. The Alternator is not Recharging the Battery while the Motor is Running.
