discharge capacity is less than 80 of nominal capacity.
Recording cycle times. The cycle times ≥1800.
Precautions for use:
Use specific battery charger.
Do not discard the battery in fire or a heater.
Do not dismantle the battery
Do not immerse the battery in water or seawater, and keep the battery in a cool & dry
surrounding if it is idle.
Do not use or leave the battery near a heat source as fire or heater.
Do not reverse the positive and negative terminals.
Do not connect the battery to an electrical outlet directly.
Do not short-circuit the battery by directly connecting the positive and negative terminals
with metal objects.
Do not transport or store the battery together with metal objects such as hairpins, necklaces,
etc.
Do not strike, trample or throw the battery.
Do not directly solder the battery and pierce the battery with a nail or other sharp objects.
Do not use or keep the battery under high temperature for example, under strong sunlight
or in an extremely hot vehicle. Otherwise, the battery would be overheated, firing, out of
operation or service life decreased.
Do not use the battery in a location with high static or intense magnetic field. Otherwise,
the safety devices may be damaged, causing hidden threat against safety.
