Lead - Acid Energy Storage Batteries Use Guide

　　Lead - acid energy storage batteries are widely used in various applications due to their relatively low cost and high reliability. Here is a comprehensive use guide for lead - acid batteries.

　　Before using a lead - acid battery, it is essential to check its physical condition. Inspect the battery casing for any signs of cracks, leaks, or damage. A damaged battery can be dangerous as it may leak acid, which can cause harm to people and equipment. Also, check the electrolyte level. In flooded lead - acid batteries, the electrolyte should cover the plates. If the level is too low, distilled water should be added carefully.

　　When charging a lead - acid battery, use a charger that is specifically designed for lead - acid batteries. Overcharging can cause the battery to overheat and may lead to gassing, which can reduce the battery's lifespan. Follow the charger's instructions carefully regarding the charging voltage and current. For example, for a 12 - volt lead - acid battery, the charging voltage should typically be around 13.8 - 14.4 volts.

　　During discharge, do not allow the battery to be completely drained. Deep - discharging a lead - acid battery can cause sulfation, where lead sulfate crystals form on the battery plates, reducing the battery's capacity. It is recommended to stop discharging the battery when its voltage reaches around 10.5 - 11 volts for a 12 - volt battery.

　　In applications where multiple lead - acid batteries are connected in series or parallel, ensure proper connection. In a series connection, the positive terminal of one battery is connected to the negative terminal of the next battery to increase the overall voltage. In a parallel connection, the positive terminals are connected together, and the negative terminals are connected together to increase the overall capacity. Make sure the connections are tight to avoid voltage drops and overheating.
