Batteries are damaged because the onsite equipment operating environment or external
power parameters do not meet the environment requirements for normal operation, for
example, the actual operating temperature of batteries is too high or too low, or the power
grid is unstable and experiences outages frequently.
Batteries are damaged, fall, leak, or crack due to improper operations or incorrect connec-
tion.
After being installed and connected to the system, the batteries are not powered on in time
due to your reasons, which causes damage to the batteries due to overdischarge.
Batteries are damaged because they are not accepted in time due to your reasons.
You set battery operating parameters incorrectly.
You use batteries of different types together, causing acceleration of capacity attenuation.
For example, you use our batteries together with batteries of other vendors or with batteries
of different rated capacity.
You maintain batteries improperly, causing frequent overdischarge; you expand the load
capacity without notifying us; or you have not fully charged the batteries for a long time.
You do not perform battery maintenance based on the operation guide, such as failure to
check battery terminals regularly.
Batteries are damaged because you do not store them in accordance with storage
requirements (for example, in an environment that is damp or prone to rain).
Batteries are not charged as required during storage due to your reasons, resulting in
capacity loss or other irreversible damages to the batteries.
Batteries are damaged due to your or a third party's reasons, for example, relocating or
reinstalling the batteries without complying with the Company's requirements.
You change the battery use scenarios without notifying the Company.
You connect extra loads to the batteries.
The battery storage period has exceeded the upper limit.
The battery warranty period has expired. You are advised not to use a battery whose
warranty period has expired, as this poses safety risks.
General Requirements
Before installing, operating, and maintaining batteries, read the battery instructions and
comply with its requirements. The safety precautions specified in this document are highly
important and require special attention.
Use batteries within the specified temperature range. 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.
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.
Install batteries within 24 hours after unpacking. If the batteries cannot be installed in time, put
them in the original packaging and place them in a dry indoor environment without corrosive
gases. Power on the ESS within 24 hours after installation. The process from unpacking
batteries to powering on the system must be completed within 72 hours. During routine main-
tenance,ensure that the power-off time does not exceed 24 hours.
