Storage of pack
The packs are requested to be stored under the following conditions:
a. Indoor storage in a cool circumstances without direct sun light on the packs or cartons.
b. Store batteries in a dry location with low humidity, and a temperature range of – 20°C to +30°C. In case of the long term storage.
c. As long-term storage can accelerate battery self-discharge and lead to the deactivation of the batteries. To minimize the deactivation effect, store battery packs in a temperature range of +10°C to +30°C.
d. When charging for the first time after long-term storage, deactivation of the packs may have led to decreased capacity. Recover such packs to original performance through repeating several cycles of full charging and discharging.
e. When store packs for more than 6 month, charge at least once charring require per 6 months to prevent leakage and deterioration in performance due to self-discharging.
Charging pack
Use suitable charger with the specified voltage and current. We strongly recommend CTECH and CPKD smart battery charger. We can recommend the usage or specification of the charger manufacturing. If you want to get the information about it, please contact us.
Never attempt reverse charging. Charring with polarity reversed can cause a reversal in battery polarity, causing gas pressure inside of the battery to rise, which can be lead to leakage of the batteries in the pack.
Avoid overcharging. Repeated overcharging can be lead to deterioration in pack performance. And Over-heat occurred.
Charging efficiency drops at temperatures above 40°C.
Protection from unexpected damaged to pack
(+) and/or (-) terminals must not be connected in metal wire, necklace, chains.
Do not drop packs from height in order to prevent them from possible malfunction or damage.
Do not twist or bend packs in order to prevent possible damage.
For Safety
Do not disassemble packs.
Do not use pack when something abnormal found such as smells, deformation, discoloration, and so on.
Do not re-use Li-ion cells or other parts after removing from the packs.
When the electrolyte leakage occurs, do not touch the liquid.
Once watered, packs may have potential malfunctions. Do not use those packs.
Do not have packs in the hot-temperature (60°C or more).
Do not put packs into fire.
Do not crush/nail pack.
Do not apply solder directly to packs.
