Dischargetemperature:-20~ +55℃
4.2.2Storageandtransportationtemperature:-5 ~+ 45℃
Transportation:
The power bank shall be packed into boxes for transportation under half
charged
state (50 ~ 70% charged state). During transportation, it shall prevent
violent vibration, impact or extrusion, sun, and rain. It shall be suitable
for transportation by ordinary
means of transportation such as automobile, train, ship, and aircraft.
Storage:
The storage temperature of the cell must be within the range of – 20 ~ 45 ℃. The long-term storage power bank (more than 3 months) must be placed in an environment with a temperature of 20 ± 5 ℃ and a humidity of 65 ± 20% RH. The storage voltage is 3.7V ~ 3.9v, avoid contact with corrosive substances, and stay away from fire and heat sources.
