Longer life of battery

The following innovative systems extend the battery's life approx.50% longer.
1. Conditioning charge
The charger receives distinctive data (temperature, history of usage ect.)
from built-in memory chip installed in battery, and decides the most suitable conditions to charge the battery.
The conditioning charge will start, when the battery is employed repeatedly under the following conditions,
which have bad influence on battery's life.
1. Charge under high room temperature (higher than 40°C)
2. Charge under low room temperature (lower than 10°C)
3. Recharge for full charged battery
4. Over discharge (continue to discharge battery in spite of machine's power down.)
Even if the cooling system does not work (because of breakdown of fan or obstruction of vent etc.),
the conditioning charge functions and starts to charge selecting the most friendly method to the battery.
2. Cooling system
The cooling fan prevents the over heat on battery and keep the optimum temperature for charging.
3. The charging control system
This system controls the output current depending on the temperature on the battery in charging process.

Impossible to charge, because
* the life of battery is over.
or
* the vent on charger or battery is clogged.
Conditioning charge is started.
The charging time can be longer than usual.
Breakage on cooling system
(The vent of charger or battery is clogged, or
the cooling fan is damaged.)
