What chargers can I use?
We recommend that the charger you use should be designed for charging Lithium batteries. SLA chargers can be used but can potentially damage or under charge the battery. The lithium charger should employ a constant current (CC) and constant voltage (CV) charge. The constant current is dependent on the capacity (amperes hour rating) of the Lithium battery and is typically 1C (0.2C to 0.5C is recommended) or less, e.g. a 9 Ah battery should be charged at 9 A or less. The constant voltage should be a minimum of 14.6 V on a 12V system (3.65V x 4 Cells).
Alternatively, A standard constant voltage lead acid battery charger can be used to charge the Lithium Batteries, as long as they meet the following standards:
- Charger must not contain an equalization setting
- Maximum charge voltage of 14.6V
- Recommended float charge voltage of 13.8V
- A charger with Lithium Iron Phosphate setting is recommended
- Some smart or multi-stage lead acid battery chargers have a feature that detects OCV, so it would refuse to charge the over-discharged lithium battery
