Cleaning
The lithium batteries are maintenance-free. Occasionally clean the product with a damp cloth.
Storage
Battery is shipped in shutdown mode, and SOC is about 30% by air shipment, about 50% SOC by sea shipment. The storage environment requirement is as follows:
| Storage Temperature range ℃ (At 50% SOC in shutdown mode and specified temp, recoverable capacity in % vs time/30% ) | -20 °C~25 °C ＜18 months | Max. 80% RH |
| 25 °C~45 °C ＜3 months | Max. 80 % RH | |
| 45 °C~60 °C ＜1 month | Max. 80 % RH | |
| 20±5 °C is the recommended storage temperature |
Do a cycle test when the storage reaches 12 months in the warehouse (based on the date of manufacture on the label). After that, the battery voltage to be checked every three months. Battery Pack Voltage ≤12 V, need to do second cycle test. And after another year, do a cycle test.
