Introduction
Proper charging plays a crucial role in maintaining battery performance and extending lifespan. Although lead-carbon batteries are more tolerant than traditional lead-acid batteries, correct charging procedures are still essential.
Three Stages of Charging
Bulk Charging
The first stage uses a high charging current to quickly restore battery capacity.
Typical voltage range:
2.35V–2.40V per cell
Absorption Charging
During this stage, charging current gradually decreases while voltage remains constant.
This helps complete the chemical reactions inside the battery.
Float Charging
Float charging maintains the battery in a fully charged condition.
Typical voltage:
2.23V–2.27V per cell
Recommended Charging Current
Charging current should usually be:
0.1C to 0.2C
For example:
100Ah battery → 10A–20A charging current.
Conclusion
Proper charging practices ensure:
- Stable battery performance
- Longer service life
- Higher energy efficiency
Always follow the manufacturer’s recommended charging parameters.
