2. The necessity of adding water to the battery
During the charging and discharging process of the battery, the electrolyte will gradually evaporate, causing the liquid level to drop. If distilled water is not replenished in time, the plates will oxidize when exposed to the air, seriously affecting the battery life. According to recent data,80% of batteries are scrapped earlyRelated to water shortage.
3. Detailed steps for adding water to the battery
