Charging solar batteries with a regular battery charger is not advisable or practical. Solar batteries, also known as deep-cycle batteries or solar storage batteries, are specifically designed to store energy generated from solar panels or other renewable energy sources. They require a dedicated solar charge controller to ensure proper charging.

Solar batteries can be charged using solar charge controllers, which regulate the voltage and current from solar panels to optimize the charging process. These charge controllers prevent overcharging, a situation where the battery receives too much voltage and current, which can cause permanent damage. Additionally, they manage the charging profile based on the battery’s chemistry, capacity, and state of charge. Source
