Battery inspection processing.deep cycle solar battery

　　First, the battery is maintained and charged, and then discharge at a 2H rate at a 2H rate. During the discharge process, the battery voltage was continuously measured, and the "backward" battery with insufficient discharge capacity was selected for treatment. First replenish dilute sulfuric acid with 1.05g/cm3 to see that there is a flow electrolyte appearing, and then continue to charge for 12 ~ 15h. When charging, pay attention not to exceed 50 degrees the temperature of the battery. After the charging is over, static 0.5 ~ 4h, and redefine 2H rate discharge. During the discharge process, measure the value of the single voltage. If the discharge time does not reach the standard or the single voltage to 1.6V, the discharge time is large and the normal single -cell battery is large (the difference between the factory is more than 5 minutes, six months in six months, six months in six months, and six months. The difference is more than 8 minutes, the difference between nine months is more than 10 minutes, and the difference between 13 months is more than 15 minutes), the above -mentioned charging and discharge program operations are required until they meet the requirements.

　　If the battery capacity is not significantly increased or still about 0V low pressure after repeated charging circulation. This battery generally has a short circuit, or the active substance is severely softened. Severe irreversible sulfuric acidization, etc., cannot be repaired, and should be scrapped. For those who meet the requirements, you can continue to use the battery. Under the charging conditions of the constant voltage 15V/piece, the electrolyte flowing out of the battery should be removed, the battery surface is cleaned, and the cap valve is available. good
