1. Check the NP battery regularly. Replace the NP battery if there is any abnormal performance, cracking and deformation of the tank shell and lid and leakage occurs. When checking the NP battery, clean it with a cloth soaked with water or warm water if it is contaminated with dust. Do not use gasoline, banana water and other organic solvents or oils for cleaning. In addition, please avoid using chemical fiber cloth.
2. When floating charging, if the total voltage of THE NP battery in the charging process or the indicator value of the voltmeter on the indicator board 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 battery, the cause should be investigated and dealt with.
Excerpt from NP Operation Manual (once a month)
Use distinction: float charging
Check items: Total voltage of the battery during charging
Method: The charger's voltmeter shows the total voltage
Benchmark: 2.275V (single cell 25℃) * cell number * only number
Disposal: Revise to base value if there are differences
3. For the emergency power supply equipment used as fire fighting equipment, please check it according to "Inspection Benchmark for Emergency Power Supply for Fire Fighting Equipment (Battery Equipment)" or "Inspection Essentials".
4. If there is a life limit on the battery, please observe it.
