Hi,
Yes, our CH-LA1230 lead acid charger can charge 81Ah battery, the charging time is calculate as: Capacity of the battery / charger's output current. In this case, the charging time will be around 81/3= 27hrs.
If you want quicker, you may choose higher output current charger, for example, 12V 10A charger.

Here is a step by step guide to choose a lead acid charger for 12V 81Ah
1. Charger Voltage
- Charger output voltage must match the battery's voltage. For a 12V battery, the charger should provide a regulated output of 12V to 14.7V (depending on the charging stage).
- Bulk/Absorption Stage: 14.2V–14.7V
- Float Stage: 13.5V–13.8V
2. Charger Current (Amperage)
- The charging current should be chosen based on the battery's capacity:
- The recommended charge rate for lead-acid batteries is 10-30% of the battery's Ah capacity.
- For an 81Ah battery:
- Minimum Current: ~8A (10% of 81Ah)
- Maximum Current: ~24A (30% of 81Ah)
- A charger with 10A–15A output is a safe and efficient choice.
3. Battery Type Compatibility
- Ensure the charger is compatible with your battery type (e.g., flooded, AGM, or gel lead-acid batteries). Many modern chargers can automatically detect and adjust for different types.
4. Safety Features
- Choose a charger with built-in safety features such as:
- Reverse polarity protection
- Overload protection
- Overcharging prevention
- Short-circuit protection
5. Additional Features
- Automatic Shutoff: Stops charging once the battery is fully charged.
- Display Indicators: Shows charging status and battery health.
