7. Before unplugging the battery, in order to avoid sparks, be sure to turn off the charger switch.
8. For traction batteries, keep the electrolyte level not lower than the electrode plate. Distilled water (or deionized water) must be used when adding liquid, and the refilling of distilled water (or deionized water) should be done more than 1 hour after the end of charging.
9. After the battery is fully charged, it must not be recharged within 24 hours before being put into use, otherwise the battery will be damaged due to excessive current.
10. When the battery power is insufficient, it should be charged in time, otherwise the battery and other related parts will be damaged due to over-discharge (low voltage).
11. Since the battery is a vulnerable and consumable part, its service life mainly depends on the timeliness and correctness of its charging and maintenance operations, so the battery is not suitable for the scope of the warranty period.
12. If the electric products are not used for a long time, the battery must be fully charged and placed in a dry and water-free room and be balanced regularly.
