Maintaining lead-acid batteries – for maximum service life
Storing lead-acid batteries:
- Dry, cool environment
Store lead-acid batteries in a dry, cool place protected from direct sunlight and moisture (room temperature). Excessively high temperatures accelerate self-discharge and promote ageing of the lead-acid battery. - Regular inspection
Check lead-acid batteries regularly for corrosion and damage. Avoid knocks, drops or impacts, as these can compromise safety and performance. Do not continue using batteries with visible damage or deformation; dispose of them properly. - Storage duration
When stored in a cool place, a lead-acid battery can be stored for 3–5 years. Ideally, it should not be stored for longer than six months without recharging to avoid deep discharge.
Charging lead-acid batteries:
- Suitable Charger
Use a Charger that is specifically suitable for lead-acid batteries. Observe the manufacturer’s datasheet and the correct voltage and current. - Avoid overcharging
Do not overcharge lead-acid batteries, as this can lead to overheating and a shorter service life. Modern chargers switch off automatically or reduce the current when the battery is full. - Ventilation
Charge the batteries in a well-ventilated room. Gases are produced during charging, which are highly flammable. During the charging process, check the condition of the battery regularly.
Conclusion
Lead-acid batteries are reliable energy storage devices, and their service life depends on proper maintenance. Careful storage and correct charging are essential to maintain the battery’s performance. Would you like to learn more about battery care and storage?
