Nanchang LC-P12100 Panasonic Panasonic battery manufacturers offer batteries need regular checks as follows: 1. The terminal voltage; 2. loose joints, fever, corrosion (should be cleared up, good corrosion protection); 3. Battery casing leaks and deformation; 4. pole, safety around whether there is mist escaping (frosting). Second, the initial use of the sealed battery prior to use need not be the initial charge, but should supplement charge. Supplementary charge should be limiting constant voltage charging method, the charging voltage shall be specified provisions, under normal circumstances (when the battery storage does not exceed six months, the ambient temperature is 25 ℃) supplementary charge voltage and charge time are as follows: single cell voltage (V ) Charging time (H) 2.23 2 ~ 3 天 2.30 ~ 2.33V 1 ~ 2 days at the temperature conditions when other charge time should be adjusted. If the ambient temperature between 10 ~ 20 ℃, the charging time should be doubled, if the ambient temperature is higher than 25 ℃, the charging time should be shortened. Third, the float voltage when the ambient temperature is 20 ~ 29 ℃, the average battery float voltage of 2.23 volts per unit cell, different temperature ranges according to the following criteria to determine the float voltage: Ambient Temperature (℃) float voltage ( V) are charging pressure Yuasa battery charge voltage can be set to 2.30 ~ 2.33V / only, specific requirements are as follows: 1. there is one or more lower than the float voltage 2.18V / only, handling about 50% of the battery release After the capacity, it is recommended in the manual are charging case, charging two to three days, as is still recoverable, please contact us; 2. release more than 20% of rated capacity, should auto BC; 3.10 weeks are filled automatically once; 4. Automatic charging time are set to 15h. V. Others 1. After the battery discharge, you should immediately recharge, so as to avoid hold time is too long, you can not restore the capacity. 2. The battery should be used to avoid large or small current discharge, the discharge voltage is not less than the battery termination voltage, avoid deep discharge. 3. In normal use, the battery can not open the safety valve, so as not to affect the safety and reliability of the battery. 4. Battery carrying strings are connected in parallel as well as loading and unloading, should prevent battery short circuit, the use of tools must be insulated, connecting bolts must be tightened. 5. 80% lower than the rated capacity of the battery, should be updated. ? Resistance to overcharge performance: 25 degrees Celsius, the fully charged state were 0.1CA charge for 48 hours, no leakage, no cell expansion and rupture. Open circuit voltage is normal. Capacity retention rate of over 95%. 7. ? Good resistance to high current: Panasonic battery is fully charged state 2CA discharge 5 minutes or 10CA discharge for 5 seconds. No conductive part of the fuse, without the appearance of deformation. Second, the product structure:?
