Maintenance & Storage
08MAINTENANCE & STORAGE
Fully power off before maintenance
8.1 Maintenance Safety Precautions
- Before maintenance, the battery must be completely de-energized (disconnect both the grid and the battery side), following the principle of "de-energize → prevent unintended re-closing → verify no voltage → grounding and short-circuit protection → cover adjacent live parts"
- Hang a "Do Not Close" warning tag on the switch position to prevent unintended power restoration
- Before maintenance, disconnect all battery terminals and circuit connectors, and install protective caps on the terminals; use insulated tools and never wear jewelry, watches, or other metal accessories
8.2 Routine Maintenance Requirements
- When replacing parts, always use spare parts of the same type and specification
- Do not spray paint on any internal or external parts of the battery, and do not clean the battery with cleaning solvents
- If any abnormality is found, contact the supplier within 24 hours
- During daily use, keep the battery SOC above 5%, and recharge within 48 hours after a full discharge to avoid over-discharge
8.3 Post-Maintenance Requirements
- After maintenance, clear all tools and materials and confirm that no metal foreign objects are left inside or on top of the battery
- Confirm that terminal protective caps, guards, etc., are all restored in place before re-energizing
8.4 Long-Term Storage
If the battery will not be used for an extended period, store and maintain it as follows:
- Fully charge the battery, then switch off the circuit breaker and the ON/OFF switch (BMS off)
- Check the battery voltage at least every 3 months. If the voltage is below 51V, recharge promptly
- Store the battery in a dry, clean, well-ventilated indoor location, away from direct sunlight and rain, and away from high-temperature heat sources, open flames, and flammable or explosive materials
- During storage, the battery should be completely disconnected from external equipment, and all indicators should be off
- The floor of the storage area should be level and solid, and qualified fire protection facilities (e.g., dry powder extinguishers, fire sand) should be provided
- Handle with care during transport and storage; dropping, collision, tipping, side placement, and tilting are prohibited
DANGER
Battery damage caused by failure to recharge in time is not covered by the warranty. Long-term storage without recharging will over-discharge the battery, causing irreversible capacity loss or even scrapping the battery.
