- Charge until the battery is fully charged. The battery can be recharged over 90% in less than one hour with an appropriate charger.
- Disconnect the charger's negative lead first, then the positive lead.
- Terminal Inspection: Periodically inspect battery terminals for cleanliness and tightness. Clean any corrosion with a wire brush and a baking soda solution (1 part baking soda to 10 parts water), then rinse with clean water and dry thoroughly.
- Battery Case: Keep the battery case clean and dry.
6. Troubleshooting
If you experience issues with your Power Max battery, consider the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not holding charge | Insufficient charging, parasitic drain, aging battery, faulty charging system. | Ensure regular charging, especially when not in use. Check vehicle's charging system. Inspect for electrical drains. If battery is old, consider replacement. |
| Slow cranking or dim lights | Low battery charge, poor terminal connections. | Charge the battery fully. Clean and tighten battery terminals. |
| Battery appears to be leaking | Physical damage to the case, overcharging causing pressure buildup. | Immediately isolate the battery. Wear protective gear. Clean up any spilled electrolyte with baking soda. Inspect for physical damage. If damaged, replace the battery. Ensure your charging system is not overcharging. |
