special attention. For additional safety precautions, see the instructions
provided by the battery manufacturer.
● Use batteries within the temperature range specied in this document. When
the ambient temperature of the batteries is lower than the allowed range, do
not charge the batteries to prevent internal short circuits caused during low-
temperature charging.
● Do not reversely connect the positive and negative battery terminals.
Otherwise, a battery alarm will be generated and batteries may be damaged.
● Before unpacking batteries, check whether the packaging is intact. Do not use
batteries with damaged packaging. If any damage is found, notify the carrier
and manufacturer immediately.
● In an indoor scenario, you are advised to power on a battery within seven
days after unpacking. If the battery cannot be powered on in time, place it in
a dry indoor environment without corrosive gas.
● Do not use batteries that are faulty or damaged (such as damage caused
when a battery is dropped, bumped, or dented on the enclosure). Damaged
batteries may release
ammable gases. Do not store damaged batteries near
other equipment or ammable materials. Only professionals are allowed to
access the batteries.
● Before working on a battery, ensure that there is no irritant or scorched smell
around the battery.
● When installing batteries, do not place installation tools, metal parts, or
sundries on the batteries. After the installation is complete, clean up the
objects on the batteries and the surrounding area.
● If a battery is accidentally exposed to water, do not install it. Move it to a safe
place for isolation and contact technical engineers in a timely manner.
● Check whether the positive and negative battery terminals are grounded
unexpectedly. If so, disconnect the battery terminals from the ground.
● Do not perform welding or grinding work around batteries to prevent
re
caused by electric sparks or arcs.
● If batteries are left unused for a long period of time, store and recharge them
according to the requirements in this document.
● Do not charge or discharge batteries by using a device that does not comply
with local laws and regulations.
● Keep the battery loop disconnected during installation and maintenance.
● Monitor damaged batteries during storage for signs of smoke,
ame,
electrolyte leakage, or heat.
● If a battery is faulty, its surface temperature may be high. Do not touch the
battery to avoid scalds.
Short-Circuit Protection
● When installing and maintaining batteries, wrap the exposed cable terminals
on the batteries with insulation tape.
● Avoid foreign objects (such as conductive objects, screws, and liquids) from
entering a battery, as this may cause short circuits.
