< br >< /b >Miady Rechargeable Sealed Lead Acid Battery Daily maintenance< br > < br >< /b >About charging tips:< br > < br >(1) Carefully read and master each charging method and charging conditions in the manual.< br > < br >(2) Do not charge the battery where there is direct sunlight.< br > < br >(3) When charging, don't let the battery get close to the heater or the light source that can generate more heat energy.< br > < br >(4) Please charge the battery according to the time specified in the instruction manual, or charge it until the fully charged indicator light is on.< br > < br >(5) Avoid frequent overcharge, which will shorten the service life of the battery.< br > < br >(6) Recycled batteries shall be continuously charged for no more than 24 hours.< br > < br >(7) Recycled batteries, please do not charge in parallel.< br > < br >< /b >About discharge tips:< br > < br >(1) The level of open circuit voltage during discharge depends on the magnitude of discharge current. The greater the discharge current, the lower the open circuit voltage; conversely, the smaller the discharge current, the higher the open circuit voltage.< br > < br >(2) It is very important to avoid over discharge, and the battery should be charged immediately after discharge.< br > < br >< /b >About store tips:< br > < br >(1) Store the battery in a stable position, and avoid being close to metal or other conductive materials.< br > < br >(2) Please fully charge the battery before storage.< br > < br >(3) If it doesn't use within six months, store the battery at 77 ℉(25 ℃ ) to recharge the battery at least once. When the ambient temperature is about 50℉(10℃), the charging interval can be shortened by half.< br > < br >(4) The battery should be put into use as soon as possible after being bought back.< br > < br >< /b >For Other precautio< br > < br >(1) When cleaning the battery, please use a soft cloth, and do not use organic solvents such as alcohol and gasoline.< br > < br >(2) Do not short-circuit the battery.< br > < br >(3) Do not cut open the battery to avoid touching the leaked sulfuric acid solution.< br > < br >(4) If sulfuric acid is splashed into your eyes, please rinse with plenty of water and see a doctor immediately if necessary.< br > < br >(5) Do not throw the battery into the fire for treatment.< br > < br >(6) Don't mix batteries with different models, capacities, manufacturers, charging and discharging degrees and timely lengths.< br > < br >(7) When designing the charger, it should be considered that it cannot damage the battery, so it should have short circuit protection and overcharge protection.< br > < br >(8) When the battery is used under vibration conditions, such as motorcycles, engineering vehicles and lawn mowers, an anti-vibration device should be added to protect the battery. In addition, the battery should be placed vertically.< br >
