It is recommended that the battery system be cleaned periodically. If the enclosure is dirty, please use a soft, dry brush or a dust collector to remove the dust. Liquids such as solvents, abrasives, or corrosive liquids should not be used to clean the enclosure.
Maintenance
The battery module should be stored in an environment with a temperature range between -10°C～+50°C, and charged regularly according to the table below with no more than 0.5 C (C-rate is a measure of the rate at which a battery is charged and discharged relative to its maximum capacity) to the SOC of 30% after a long time of storage.
| Storage environment temperature | Relative humidity of the storage environment | Storage time | SOC |
| Below -10℃ | / | Not allowed | / |
| -10~25℃ | 5%~70% | ≤ 12 months | 25%≤SOC≤60% |
| 25~35℃ | 5%~70% | ≤ 6 months | 25%≤SOC≤60% |
| 35~50℃ | 5%~70% | ≤ 3 months | 25%≤SOC≤60% |
| Above 50℃ | / | Not allowed | / |
