1, regularly check the NP standby battery, such as abnormal performance, tank shell, lid cracking, deformation and other damage and leakage, to replace the NP standby battery. When checking the NP standby battery, clean it with a cloth soaked with water or warm water if it is contaminated by dust. Do not use gasoline, banana water and other organic solvents or oils for cleaning. In addition, please avoid using chemical fabric sheets.
2. When floating charging, the total voltage or the indicating value of the voltmeter on the indicator panel of the NP standby battery in the charging process deviates from the reference value shown in the table below, or the terminal voltage deviates from the reference value in the charging process of a single standby battery, the cause should be investigated and treated.
Excerpt from NP Instruction Manual (Once a month)
Usage distinction: float charging
Check item: Reserve the total voltage of the battery when charging
Method: The charger's voltmeter displays the total voltage
Benchmark: 2.275V (25℃ for a single cell) * number of cells * number of only
Disposal: If there are discrepancies, correct to the base value
3. For emergency power equipment used as fire fighting equipment, please check according to the "Inspection Standards of Emergency Power for Fire Fighting Equipment (Storage standby Battery Equipment)" or "Inspection Essentials".
4. If there is a service life on the reserve battery, please abide by it.
