Lead-acid batteries commonly used in diesel generator sets are mainly divided into two categories, namely dry-charge batteries and maintenance-free batteries.
1. Dry-charged battery: Its full name is dry-charged lead-acid battery. The main feature is that the negative plate has a high storage capacity. In a completely dry state, it can save the obtained power within two years. Just add electrolyte and wait for 20-30 minutes before use. Its main advantages are stable voltage and low price; its disadvantages are low specific energy (that is, electric energy stored per kilogram of battery), short service life and frequent routine maintenance.
2. Maintenance-free storage battery: Due to its structural advantages, the maintenance-free storage battery consumes very little electrolyte and basically does not need to be supplemented with distilled water during its service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge. The service life is generally twice that of ordinary batteries. There are also two types of maintenance-free batteries on the market: the first is that the electrolyte is added once at the time of purchase and does not require maintenance (addition of supplementary fluid) after use; the other is that the battery itself has been filled with electrolyte and sealed up when it leaves the factory. , The user cannot add refill at all.
Lead-acid batteries are available in 2.4 volts, 4 volts, 6 volts, 8 volts, 12 volts, and 24 volts series, with capacities ranging from 200 mAh to 3000 amp hours. Generally diesel generator sets use 12V or 24V batteries to start.
