12.4 Battery Storage and Charge
Battery Acceptance Inspection
A battery charge label must be put on the battery packing case to indicate the
latest charge time.
Battery Storage Requirements
1. Place batteries according to the signs on the packing case during storage. Do
not put batteries upside down or sidelong.
2. Stack battery packing cases in compliance with the stacking requirements on
the outer package.
3. Handle batteries with caution to avoid damage.
4. The storage environment requirements are as follows:
– Ambient temperature: –10°C to +55°C; recommended storage
temperature: 20°C–30°C
– Relative humidity: 5% to 80% RH
– Dry, clean, and well-ventilated
– Away from corrosive organic solvents and gases
– Away from direct sunlight
– At least 2 meters away from heat sources
5. Before storing batteries, disconnect them from external devices.
6. AC mains input voltage at the charge position: single-phase power grid,
200/208/220/230/240 V AC
7. The warehouse keeper should collect battery storage information every
month and periodically report the battery inventory information to the
planning department. The batteries that have been stored for nearly 15
months (at –10°C to +25°C), 9 months (at 25°C–35°C), or 6 months (at 35°C–
55°C) should be charged in a timely manner.
8. Batteries should be delivered based on the
"rst in, rst out" rule.
9. After the battery production test is complete and before the batteries are
stored, the batteries must be charged to at least 50% of the SOC.
