4. Setup and Connection
Follow these steps to properly connect your 10L0L Golf Cart Battery Charger:
- Verify Compatibility: Ensure your golf cart is a 36V EZGO TXT model and uses a "D" Style Powerwise plug.
- Connect AC Power: Plug the charger's AC power cord into a standard 110V grounded wall outlet. The charger's internal systems will initialize.
- Connect to Golf Cart: Approximately 10 seconds after connecting to AC power, insert the charger's D-style plug firmly into the charging port of your 36V EZGO TXT golf cart.
- Confirm Charging: Observe the charging indicator lights on the charger to confirm that charging has begun. Refer to Section 5 for details on indicator lights.
IMPORTANT: Always connect the AC power first, then the DC plug to the golf cart. Reversing this order may prevent the charger from initiating the charging cycle.

5. Operating Instructions
Charging Process:
Once properly connected, the charger will automatically begin its multi-stage charging process, which typically includes constant current and constant voltage phases. The charging indicator lights provide real-time status updates.
Charging Indicator Lights:
The charger features a circular indicator with different colored segments to show the charging progress:
Figure 5.1: Detailed view of the charging indicator.
- Red Light: Indicates the battery is currently charging (below 80% capacity).
- Yellow Light: Indicates the battery has reached approximately 80% of its capacity.
- Green Light: Indicates the battery is fully charged (100%). The charger will then switch to a trickle charge mode to maintain the battery.
6. Battery Type Selection
This charger is equipped with three distinct charging algorithms to optimize charging for different battery chemistries. It is crucial to select the correct algorithm for your battery type to ensure efficient charging and battery longevity.
Figure 6.1: Battery algorithm selection panel on the charger.
On the charger's control panel, locate the "Charging Algorithm Selection" area. You will find checkboxes or a similar mechanism to choose from the following battery types:
- Flooded/Lead-acid battery: For traditional wet-cell batteries.
- Maintenance-free battery: For sealed lead-acid (SLA) or gel batteries.
- Lithium iron phosphate battery: For LiFePO4 batteries.
Ensure the correct battery type is selected before initiating charging. Incorrect selection can damage your battery or reduce its performance.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your charger:
- Cleaning: Periodically wipe the charger's exterior with a dry, soft cloth. Do not use harsh chemicals or abrasive cleaners.
- Cable Inspection: Regularly inspect the AC power cord and the D-style plug for any signs of damage, fraying, or corrosion. Replace damaged cables immediately.
- Storage: When not in use, store the charger in a cool, dry place, away from direct sunlight and extreme temperatures.
- Ventilation: Ensure the heat sink fins are free from dust and debris to maintain proper heat dissipation.
8. Troubleshooting
If you encounter issues with your 10L0L Golf Cart Battery Charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger does not turn on or start charging. | Incorrect connection order; no AC power; faulty outlet; damaged cable. | Ensure AC power is connected first, then DC to golf cart (wait 10 seconds). Check AC outlet and power cord. |
| Battery does not fully charge (e.g., stuck on yellow light). | Incorrect battery type selected; battery issue; charger fault. | Verify the correct charging algorithm is selected (see Section 6). Inspect battery condition. Contact support if issue persists. |
| Charger is hot during operation. | Normal operation; insufficient ventilation. | Some heat is normal. Ensure the charger is placed in a well-ventilated area and the heat sink is clear of obstructions. |
| Charging is slower than expected. | Battery condition; environmental factors. | Older or heavily discharged batteries may take longer. Ensure ambient temperature is within operating range. |
If troubleshooting steps do not resolve the issue, please contact 10L0L customer support for assistance.
