My Powerwise charger stops charging too early

I can’t figure out why my Powerwise charger stops mid-charge! It starts off well but then cuts out after just 30 minutes, leaving my batteries half-charged. This is really messing up my golf cart usage. Has anyone faced and solved this annoying problem?


I had a similar headache with my charger. Turned out, the issue was not with the charger but the batteries. After swapping them out, the charger was back to its normal cycle. It seems like the charger was prematurely stopping due to the batteries’ inability to hold a charge.

  • Charger stops after about 30 minutes.
  • Golf cart struggles, especially uphill.
  • Batteries not fully charged.

Possible Causes

  • Batteries losing their ability to hold a charge.
  • Poor or corroded connections in the charging system.
  • Faulty components like capacitors or control boards in the charger.

Solutions that Worked

1. Battery Replacement

What I Did: Replaced all the golf cart batteries. Outcome: Charger stopped cutting out early, and cart performance improved. Personal Experience: The cart struggled on hills, and the charger kept stopping early. New batteries fixed these issues. Steps:

  1. Determine the correct battery type and quantity for your golf cart.
  2. Safely disconnect and remove the old batteries.
  3. Install the new batteries, ensuring correct orientation and secure connections.
  4. Conduct a full charging cycle before using the cart. Expert Tip: Regularly check your batteries’ health. Aging or faulty batteries can lead to charging issues. Also, ensure the batteries are properly seated and connections are tight.

2. Individual Battery Charging

What I Did: Charged each battery separately using a 6V charger. Outcome: Balanced battery charge levels, leading to efficient charging. Personal Experience: Some batteries were less charged than others. Charging them individually helped balance the pack. Steps:

  1. Disconnect each battery from the pack for individual charging.
  2. Use a 6V charger to charge each battery, monitoring to avoid overcharging.
  3. Reconnect the batteries, ensuring proper configuration and connections.
  4. Perform a full charge cycle with the 36V charger. Expert Tip: Unevenly charged batteries can affect overall performance. Consider using a battery desulfator to rejuvenate older batteries.

3. Cleaning and Tightening Connections

What I Did: Inspected and tightened all connections in the charger circuit. Outcome: Improved charging efficiency; charger no longer stopped early. Personal Experience: Found and fixed loose and corroded connections causing charging issues. Steps:

  1. Inspect all connections in the charger and battery circuit.
  2. Clean corrosion using a wire brush or corrosion removal product.
  3. Tighten all connections for optimal contact.
  4. Test the charger to ensure the issue is resolved. Expert Tip: Use dielectric grease on connections to prevent future corrosion. Regular maintenance can prevent many charging problems.

4. Checking and Replacing Capacitor

What I Did: Tested and replaced the charger’s capacitor. Outcome: Charger functioned correctly without premature stopping. Personal Experience: Identified a faulty capacitor causing charger malfunction. Steps:

  1. Locate and safely access the charger’s capacitor.
  2. Test the capacitor with a capacitance meter.
  3. Replace the capacitor if it fails the test.
  4. Reassemble and test the charger for proper operation. Expert Tip: Be cautious when handling capacitors as they can retain a charge. Discharge the capacitor safely before testing or replacing.

5. Control Board Replacement

What I Did: Replaced the faulty control board in the charger. Outcome: Charger stopped shutting off early and fully charged the batteries. Personal Experience: Found that the control board was the root cause of the issue. Steps:

  1. Identify the correct replacement control board for your charger.
  2. Carefully remove the old board, noting all connections.
  3. Install the new board, ensuring all connections are correct.
  4. Test the charger to confirm proper functionality. Expert Tip: Control board issues can be complex. If you’re not comfortable with electrical repairs, consider seeking professional help.

Golf Cart Models Where This Worked

  • Various models with Powerwise chargers, including EZGO Marathon, Medalist, TXT, and RXV.

Remember: Safety first when dealing with electrical components. Disconnect power sources before attempting repairs. If unsure, seek professional help. Regular maintenance and checks can prevent many issues.
