● Do not use damaged battery packs (dented on the enclosure or other
damage). Damaged battery packs may cause the release of ammable gases.
Do not store damaged battery packs near undamaged products.
● Do not store damaged battery packs with ammable materials. Keep non-
professionals away from the storage area.
● Monitor damaged battery packs during storage for signs of smoke, ame,
electrolyte leakage, or heat.
Charge Requirements
● If a battery pack has not been charged for more than eight months, charge
the battery pack again. Otherwise, the battery pack performance and service
life may be aected.
● You can obtain the battery pack production completion time by querying the
delivery record based on the battery pack SN or consulting the Company's
service engineers.
Battery Pack Installation Requirements
Before installing battery packs, check whether the battery packs are abnormal. A battery
pack is deemed abnormal when any of the following symptoms occurs:
● The enclosure of the battery pack is obviously deformed or damaged.
● The voltage between the positive and negative electrodes of the battery pack is far
below the
specied range.
● Use battery packs of specied models. Using battery packs of other models
may cause damage.
● Before installing battery packs, check whether the packaging is intact. Do not
use battery packs with damaged packaging.
● Place and secure battery packs horizontally.
● When installing battery packs, do not place installation tools or other objects
on the battery packs.
● During installation, ensure that the positive and negative electrodes of battery
packs are not short-circuited.
● During installation, ensure that the terminals are tightened properly using a
torque wrench and check them regularly.
Battery Pack Short Circuit Protection
Battery pack short circuits can generate high instantaneous currents and release a
great amount of energy, which may cause equipment damage or personal injury.
● When installing and maintaining battery packs, wrap the exposed cable
terminals on the battery packs with insulation tape.
● Avoid foreign objects (such as conductive objects, screws, and liquids) from
entering battery packs, as this may cause short circuits.
