How to Charge a 12V Battery?
1 Answers
12V battery charging method: Attach the red clamp of the charger to the battery's positive terminal marked with a plus sign, and the black clamp to the negative terminal marked with a minus sign. Starting batteries sometimes become discharged due to heavy usage or prolonged storage, so they should be periodically removed from the equipment and recharged in a charging area. Supplementary charging is generally performed once a month to enhance reliability and extend service life. It is advisable to perform a supplementary charge before winter. Battery charging precautions: Initial charging: The first charge of a battery is called the initial charge, which significantly impacts the battery's lifespan and charge capacity. Insufficient charging results in lower charge capacity and shorter lifespan, while overcharging improves electrical performance but also shortens lifespan. Therefore, new batteries should undergo initial charging carefully. Dry-charged lead-acid batteries: For dry-charged lead-acid batteries, as per the user manual, if used within two years of storage, simply add the specified density of electrolyte and let it stand for 15 minutes before use without charging. However, if stored for more than two years, partial oxidation may occur on the plates. To improve charge capacity, a supplementary charge of 5-8 hours is recommended before use. Scheduled charging: When not in use for extended periods, aim to perform a health charge once a month or discharge to 50% after full charge. The optimal ambient temperature for battery charging is 25°C, which is difficult to achieve in cold winters, so indoor charging is preferable. If conditions don't permit, choose to charge during sunny daytime hours to enhance battery activity and reduce range loss.
