1. Car batteries cannot be used as solar batteries.
2. The car battery uses lead-calcium alloy as the grid, so the amount of water decomposition and water evaporation produced during charging is low, and the outer casing adopts waterproof casing. structure. , the sulfuric acid gas released is also very small, so compared with traditional batteries, it has the advantages of no need to add liquid, connect terminals, and have a long battery storage time. energy.
3. Solar batteries are the application of “storage batteries” in photovoltaic solar power generation. Currently, maintenance-free lead-acid batteries, ordinary lead-acid batteries, gel batteries. and alkaline batteries are used. There are four types of nickel-cadmium batteries.
Of course, but the following conditionsyour must be met to charge the battery:
1. Suitable charging voltage, car batteries are generally 12V, and photovoltaic cells should be connected in series: to maintain the output voltage at 13-15V;
2. Suitable charging current. The larger the photovoltaic cell area, the more appropriate photovoltaic cell area should be selected based on the charging current parameters. supplied by the battery.
3. Loading time. The lower the charging current, the longer it takes to fully charge the battery.
