3.1. Nickel Metal Hydride Battery Charger (JWC-2)
The names and functions of the Nickel Metal Hydride Battery Charger (JWC-2) are explained below.
(1) Charging System
Pre-Charging
Starts charging at low amperage if the battery voltage is abnormally low.
Quick Charging
Charges an empty battery in approximately 2.5 to 3 hours.
Refrech Charging
Refresh charging a fully charged battery takes approximately 13 to 15 hours.
(2) Refresh Function
With refresh charging, the charger discharges the battery completely before charging.
This restores battery performance by improving the internal activation of the battery. The
communication function that is built into the JWC-2 charger receives optimal refresh timing in the
form of data from the battery management system. Thus, this function informs the user of when
the battery should be refresh charged. The JWC-2 charger is designed not to refresh charge
unless the refresh lamp is blinking.
• A battery from the factory or a battery that has undergone a deep discharge
requires approximately 120 to 130% longer to charge.
• If a battery is post-charged because it was charged at a high temperature, the
post-charging for replenishment purposes could take as much as 1.5 hours
longer. Furthermore, the capacity indication during charging will take a longer
time to blink the topmost segment (fully charged).
