6.3 Keep and storage
The storage battery shall be kept in clean, dry and ventilated warehouse within the temperature range of 5
to 40℃. The valid storage period is 2 years. Within the storage period, keep the battery according to the following
requirements:
a. Avoid direct sunlight. The distance from heat source shall be no less than 2m.
b. Avoid contact with any harmful substance. No metal impurity shall fall into the battery.
c. No inversion, no mechanical collision or heavy weight is permitted.
d. Do not store the battery with electrolyte in it. In special cases where it is necessary to store with electrolyte,
the density and liquid level of electrolyte shall be adjusted to the stipulated value. Whenever one month of storage
period expires, a complementary charge shall be made with the common charge method.
6. 4 Operations of electrolyte
⑴ Density check
Use the suction type densi-meter to check density. During operation, avoid spilling out the electrolyte, and do
wear protective tools.
⑵ Operation besides check
Consult professional personnel, especially when complementing electrolyte (dilute sulfuric acid).
⑶ Electrolyte leakage
As for the electrolyte leakage resulting from the tilting and damage of storage battery, emergency treatment
shall be made at once (See emergency treatment item)
6.5 Operations for storage batteries of end service life
⑴ Operation of storage batteries during the final stage of their lifetime
When the service life of storage battery is about to terminate, the electrolyte in single cells reduces very fast.
For this reason, distilled water shall be complemented every day.
⑵ Treatment of waste batteries
For the waste batteries, draw out the electrolyte and decompose the batteries. It can be negotiated whether
the waste batteries shall be recycled by the battery manufacturer. The waste electrolyte should be disposed
according to relevant local rules and regulations.
6.6 Emergency treatment
⑴ The electrolyte is spilled on skins:
Wash with a large amount of water;
⑵ The electrolyte is spilled to eyes:
Wash with a large amount of water, and go for professional medical treatment;
⑶ The electrolyte is spilled onto clothes:
Take off the clothes immediately; after washing with water, wash with liquid soap of alkalescence;
⑷ The electrolyte leaks:
If the electrolyte leaks out, neutralize it with lime, strong carbonated soda or carbonated soda or others, and
wash with a large amount of water.
6.7 Charger
If you are using self-prepared electric charger, then the charger must live up to the following requirements:
a. Charger output voltage: 24V
b. Charger output current: 30A
If you are using the semi-electric or manually-adjustable charger, please charge the battery according to
instructions given in item 2 "Use and maintenance".
