Corrective and preventive measures for lead-acid batteries not charging properly
Corrective measures:
For batteries with sulfation, rehabilitation can be carried out. For batteries with slight sulfation, complete rehabilitation can be achieved, including capacity rehabilitation and functional rehabilitation. Rehabilitation methods include using low current for repeated charge and discharge cycles. For example, a 12V12AH battery can be charged for 12 hours with a constant current of 1.2A, discharged to 10.8V with a constant current of 0.6A, and repeated 4 times for the battery to recover.
The degree of sulfation is relatively high, and the capacity can only achieve partial recovery, which depends on the degree of sulfation.
Severe sulfation, irreversible capacity, and battery failure, due to negative plate sulfation being one of the forms of battery failure.
3) Preventive measures:
Proper use and protection of Palma batteries should prevent "over discharge, under charging" and "failure to replenish power in a timely manner" as much as possible.
1. The discharge equipment used should have termination (lower limit voltage) protection. When setting, it is determined based on the discharge current. For example, for 12V12AH discharge, the lower limit voltage is set to 10.8V for current discharge below 0.2C; for current discharge between 0.2-0.5C, the lower limit voltage is set to 10.5V; for current discharge between 0.5-1C, the lower limit voltage is set to 10.2V; for current discharge above 1C, the lower limit voltage is set to 9.6V.
2. After discharging, please do not store or place it, and recharge it immediately.
3. Please use sufficient electricity before use.
4. Even if the palm battery is not in use, it needs to be fully charged before placement.
5. Due to the installation of batteries on equipment and the influence of equipment structure and wiring, there will inevitably be more or less current leakage (ranging from a few milliamps to several tens of milliamps). Therefore, when storing equipment for a long time (exceeding), the power circuit should be disconnected (not just the electronic switch).
