If your 2001 Club Car 48-volt golf cart has new batteries but the charger shuts off shortly after starting, there could be several reasons behind this issue. One common reason is that the charger might mistakenly detect the new batteries as fully charged, especially if they were partially charged before installation. In this case, try using the cart for a short ride (15–20 minutes) to bring the battery voltage down slightly, then plug in the charger again.
Another possible cause is incorrect battery wiring. The 48V system typically uses either six 8V batteries or four 12V batteries wired in series. If there is any mistake in the wiring connections, the voltage may read incorrectly, causing the charger to behave oddly. Make sure the batteries are properly connected in series according to your cart’s configuration.
A faulty or outdated charger can also cause this problem. Older chargers may not be compatible with new battery types (especially lithium or AGM batteries) and may shut off early or not charge at all. In such cases, upgrading to a modern smart charger that works with your battery type is recommended.
Sometimes, corrosion or loose connections at the battery terminals or charger port can interrupt the charging process. Be sure to check all cables, clean the terminals, and tighten any loose connections to ensure a steady power flow.
It’s also important to note that new lead-acid batteries need a few charge/discharge cycles to reach full performance. During this break-in period, charging behavior might seem unusual. Simply use the cart as normal and monitor it over a few days.
Lastly, the Onboard Computer (OBC) in a 2001 Club Car might be causing the charger to shut off too soon. The OBC manages charging and can sometimes get “confused” after battery replacement. Resetting the OBC might solve the problem. To do this, disconnect the battery pack, turn the key switch to OFF, set the forward/reverse switch to neutral, and wait a few minutes before reconnecting the batteries.
