Battery Protection Circuitry
• Over-charge protection:
If during charge the battery voltage exceeds a preset level.
charging is automatically stopped to prevent the battery from
being overcharged. The charger will show a charging fault,
though the batteries LEDs will continue to show the battery
charge capacity. If this happens contact your supplier.
• Over-discharge protection:
If the battery voltage reaches 9.2V during discharge, the
protection circuit will operate. Then the LED indicators will not
operate. When the battery is re-charged and the voltage reaches
12.0V, the LEDs will reset and operate again.
• Over-current protection:
When exposed to a high discharge current, large in-rush current
or an external short circuit, the protection function is activated
preventing battery discharge. Then the LED indicators will not
operate. The over-current protection is automatically reset by
disconnecting the battery from equipment in use.
• Thermal protection:
If the internal temperature of the battery pack exceeds preset level, the
thermal fuse will activate and power supply will be terminated. In such
cases the battery cannot be reset. If this happens contact your supplier.
