Common failures & inspection points

●Cell ageing, imbalance, sulphation, or capacity loss causes reduced backup duration, low-voltage alarms, or failed capacity tests
●Loose, corroded, or overheated interconnections create voltage drop, hot spots, or intermittent supply
●Charger, inverter, converter, or DC-bus faults prevent proper charging or cause unstable output
●Cooling or ventilation failure raises battery or electronics temperature and may cause derating or protective shutdown
●Monitoring, BMS, sensor, or communication faults cause incorrect state-of-charge indication, nuisance alarms, or blocked operation

Service & Maintenance

Check battery condition, terminals, cleanliness, temperature, ventilation, charger status, alarms, insulation monitoring where fitted, BMS data, and emergency supply transfer. Testing and isolation must follow the battery chemistry and manufacturer safety procedure; exact limits and replacement criteria must come from approved documentation.
