Maintain a certain level of electrolyte level
According to the requirements of use, the electrolyte level should be 10-15mm above the plate. When inspecting, first use a glass tube with an inner diameter of 4 to 6 mm and a length of about 150 mm, and insert it vertically into the liquid addition port until it contacts the edge of the electrode plate, and then use the index finger to press the height of the electrolyte in the glass tube to be the electrolyte level in the battery. Above the height of the plate. After the measurement, the electrolyte in the glass tube is returned. If the liquid level is not enough, the distilled water should be added in time. Do not add spring water, river water, and tap water, or add dilute sulfuric acid, otherwise the electrolyte density will increase and the damage will be extremely bad. board. It should also be noted that distilled water should be added when the battery is in a state of charge to ensure that the electrolyte is more evenly mixed; the liquid level should not be too high to prevent electrolyte overflow during charging and discharging.
Remove the yellow-white paste on the cover in time
The yellow-white paste on the battery cover is the result of electrochemical corrosion of the electrode post due to the sulfuric acid solution splashing around the battery cover and the pole. The white substance is lead sulfate and the yellow substance is iron sulfate, which is highly corrosive and has a large electrical resistance. If it is in contact with the wire, a large contact resistance will be formed, resulting in poor electrical conductivity.
For this reason, the electrolyte splashed from the battery casing and the cover should be cleaned regularly with alkali water or with 10% soda or 10% ammonia solution so that the surface is often neutral. If there is oxide in the gap between the pole and the wire joint, it can be scraped off with a tool.
Regular recharge
Under normal circumstances, the discharged battery should be charged within 24h; for the battery on the stop machine (or large equipment not used temporarily), it must be recharged once a month; the battery used should be every two Remove it once a month for 1 charge.
Check the density of the electrolyte regularly
The electrolyte density must be adapted to the region and season. According to practical experience, in most parts of China (except the severe cold area), the relative density of newly charged battery electrolyte can reach 1.20~1.25g/m3 before and after the summer. When the used battery is recharged, the relative density of the electrolyte should be maintained. At 1.15 ~ 1.18g / cubic meter. The relative density of the electrolyte in autumn should be gradually increased from 1.18g / cubic meter to 1.25g / cubic meter, adjusted to 1.285g / cubic meter in winter, and gradually added distilled water in the Spring Festival to reduce the relative density.
