Maintenance
Battery Maintenance (Trickle Charge):
For batteries stored for extended periods, use the TKL (Trickle Charge) mode. This mode automatically maintains the battery voltage, preventing self-discharge and ensuring the battery remains ready for use. The charger will auto-detect voltage and restart charging once it drops below 12.5V.

The trickle charge feature helps maintain battery health during off-season storage.
Charger Care:
- Keep the charger clean and dry.
- Store in a cool, dry place when not in use.
- Do not expose to rain or excessive moisture.
- Inspect cables and clamps for damage before each use.
Troubleshooting
