Battery Routine Maintenance

2026-04-02

Charging Schedule: It is recommended to charge the battery after each use. If the battery is not used for an extended period, it should be charged monthly to maintain stable power levels and avoid over-discharge, which can damage battery performance and shorten service life.

Temperature Management: Keep batteries operating and stored in an environment between 15℃ and 25℃. Avoid high temperatures, direct sunlight, and freezing conditions, as extreme temperatures can accelerate aging and reduce capacity.

Appearance & Connection Inspection: Regularly check the battery casing for cracks, swelling, or leakage. Ensure terminals are clean, tight, and free of corrosion to maintain good conductivity and safe operation.

Discharge Management: Avoid deep discharge and over-discharge as much as possible. Do not leave the battery in a low-power state for a long time, as this will cause irreversible damage to the internal structure.

Storage Requirements: For long-term storage, keep the battery in a dry, ventilated area with a 50%–70% charge level. Recharge at least once every 3 months to maintain battery activity.
