activities to avoid the risk of contacting the terminals.
7.2 Inspection
Inspect for loose and/or damaged wiring and contacts, cracks, deformations, leakage or
damage of any other kind. If damage to the battery is found, it must be replaced. Do not attempt
to charge or use a damaged battery. Do not touch the liquid from a ruptured battery.
Regularly check the battery’s state of charge. Lithium Iron Phosphate batteries will slowly self-
discharge when not in use or whilst in storage.
Consider replacing the battery with a new one if you note either of the following conditions:
- The battery run time drops below 80% of the original run time.
- The battery charge time increases significantly.
7.3 Cleaning
If necessary, clean the Li-Ion battery with a soft, dry cloth. Never use liquids, solvents, or abrasives
to clean the Li-Ion battery.
7.4 Maintenance
The Li-Ion battery is maintenance free. Charge the battery to approximately > 80% of its capacity at
least once every year to preserve the battery’s capacity.
7.5 Storage
The battery product should be stored in a dry, cool and cool environment;
Generally, the maximum storage period at room temperature is 6 months. When the battery is
stored over 6 months, it is recommended to check the battery voltage. If the voltage is higher
than 48V, it can continue to store the battery. In addition, it is needed to check the voltage at
least once a month until the voltage is lower than 48V. When the voltage of the battery is lower
than 48V, it must to be charged according to the charging strategy.
The charging strategy is as follows: discharge the battery to the cutoff voltage with 0.2C
10
A
current, and then charge with 0.2C
10
A current for about 3 hours. Keep the SOC of the battery
at 40-70% when stored;
When the battery product is stored, the source of ignition or high temperature should be avoided
and it should be kept away from explosive and flammable areas.
8. Troubleshooting
To determine the status of the battery system, users must use additional battery status monitoring
