First, for short-term idle scenarios that last no more than 30 days, the recommended ambient storage temperature for lithium-ion forklift battery assemblies is controlled between -10℃ and 35℃. Under this temperature range, the internal chemical activity of the battery assembly can remain in a relatively stable state, no extra irreversible capacity loss will be caused after the battery is put back into normal use. Before placing the idle battery into storage, users are advised to arrange a full appearance inspection, confirm that the outer shell is free of damage, the electrode connection terminals are clean and dry, and place the battery in a ventilated and dry storage area away from direct sunlight and corrosive substances.

For medium-term idle storage that ranges from 30 days to 180 days, the applicable storage temperature limit should be adjusted to between 0℃ and 30℃. In this temperature interval, the self-discharge rate of the battery assembly can be maintained at a low level, which effectively reduces the extra consumption of active substances inside the electrode. It is not recommended to place the idle battery in a working area with severe temperature fluctuations, such as the side of a high-temperature industrial furnace or the open air exposed to low-temperature freezing weather. Users also need to check the state of charge of the battery once every 30 days, and keep the remaining power between 40% and 60% to avoid damage caused by excessive self-discharge.

For long-term idle scenarios that last more than 180 days, the strictest storage temperature limit is set between 10℃ and 25℃. This temperature range can minimize the irreversible attenuation of the internal chemical system of the lithium-ion forklift battery assembly, and effectively extend the overall service cycle of the product. Before long-term storage, users should disconnect the battery assembly from all external peripheral loads, and do not stack heavy objects on the outer shell of the battery during the placement process. It is also necessary to arrange a special person to check the ambient temperature data of the storage area every week, adjust the cooling or heating equipment in time to keep the temperature within the specified range, and avoid unnecessary performance loss or hidden safety risks caused by out-of-limit temperature.

In the actual use and storage process, matching corresponding storage temperature parameters according to the specific idle duration can help enterprise users reduce the comprehensive operation and maintenance cost of the electric forklift fleet, and ensure that the battery assembly can maintain stable performance when it is put back into operation.
