– The corrosive organic solvents, gases and other substances shall be kept away.
– Exposing to direct sunlight shall be avoided.
– The distance from the heat source should not be less than two meters.
5. When being stored, the battery shall be disconnected from the external connection. If there is an indicator
light on the battery panel, the indicator light shall be off.
7. The warehouse keeper shall make monthly statistics on the battery storage, and regularly inform the
planning link of the battery inventory. If any battery has been stored for nearly 15 months (-10 ℃ to
25 ℃), 9 months (25 ℃ to 35 ℃), or 6 months (35 ℃ to 55 ℃), recharging shall be arranged in time.
8. When the stored batteries are going to be delivered, the first-in first-out principle should be followed.
9. After the battery is produced and tested, it shall be recharged to at least 50% SOC before being stored. If
the device will not be used for a long period of time, discharge the battery to 45% to 60% of the battery
capacity and disconnect the battery output to avoid the battery runs out;
10. Do not touch the battery pack with wet hands.
11. Do not squeeze, drop, or pierce the battery.
12. The battery should always be disposed in accordance with local safety regulations.

8.4.2 Requirements for Charging of Battery
The batteries to be stored for a long period of time (unused, for more than 3 months) must be kept in a dry
and cool place. The storage voltage is 51V-53V. The batteries should be stored in a clean environment of 23±
2℃ and humidity of 45%-75%. If the battery will be shelved and not used for a long period of time, it should be
recharged every 3 months to ensure that the battery voltage is within the above range.
As for batteries and long-term storage, routine maintenance is required. Please charge the battery to 40%
SOC at a current of 0.2C according to the requirements in the table below.
