Caution and prohibition
Before using and handling the pack, see carefully attached “Handling Instruction Guide for LiFePO4 Battery Pack”
For safety reasons rechargeable batteries are not shipped in a low remaining capacity state. Charge before using
Do not connect multiple battery packs as parallel or serials for using. This might damage the battery pack, even reequip mint’s.
Warranty
Manufacturer will be responsible for replacing the battery pack against defects or poor workmanship for 24 mon this fromthedate of shipping. Any other problem caused by malfunction of the equipment or misuse of the battery is battery is not covered under this warranty.
Handling Instruction Guide for LiFePO4 Battery Pack
General
Battery packs supplied by Crown Micro have to be handle carefully according to the specification. Here are some more to be followed.
Crown Micro
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℃to +30℃. Incase 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℃to +30℃.
d. When charging for the first time after long-term storage, deactivation
of the packs may have led to decreased paucity. Recover such packs to original
performance through repeating several cycles of full charging and dis
charging.
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
a. Use suitable charger with the specified voltage and current. We
strongly recommend Crown Micromort battery charger. We can recommend the usage
or specification of the charger manufacturing. If you want together
information about it, please contact us.
b. Never attempt reverse charging. Charring with polarity reversed can
cause a reversal in battery polarity, causing’s pressure inside of the battery
to rise, which can be lead to leakage of the batteries in the pack.
c. Avoid overcharging. Repeated overcharging can be lead to deterioration
in pack performance. And Over heat occurred
d. Charging efficiency drops at temperatures above 40℃.
Protection from unexpected damaged to pack
a. (+) and/or (-) terminals must not be connected in metal wire,
necklace, chains.
b. Do not drop packs from height in order to prevent them from possible
malfunction or damage.
c. Do not twist or bend packs in order to prevent possible damage
For Safety
a. Do not disassemble packs
b. Do not use pack when something abnormal found such as smells,
deformation, discoloration, and soon
d. Do not re-use LiFePO4 cells or other parts after removing from the
packs.
e. When the electrolyte leakage occurs, do not touch the liquid.
f. Once watered, packs may have potential malfunctions. Do not use those
packs.
g. Do not have packs in the hot-temperature (60℃or more).|
h. Do not put packs into fire.
i. Do not crush/nail pack.
j. Do not apply solder directly to packs
