3.6.1 “Battery Type” Indicator LEDs
When a battery is plugged in to the charger, one of the two green LEDs labeled "BATTERY TYPE"
will indicate which type of battery (UBI-2590 / UBBL09 / BB-2590 or BB-390 / BB-590) is plugged in.
When the correct type of battery is indicated, the battery will be charged correctly. If the incorrect
type of battery is indicated, remove the battery from charger. The incorrect type of battery has been
detected because of defect or damage to the battery contact, or damage to the charger. A battery
that has been indicated as an incorrect battery will not charge correctly if left on the charger, and
may cause damage to the battery or charger.
3.6.2 “Charging” Indicator LEDs
The two green LEDs labeled "CHARGING" indicate the state of charge a section of the battery is in.
One indicator is for each section of the battery.
Solid green: Indicates the battery is fast charging.
Extinguished: Indicates the charge is complete.
Blinking: Indicates a trickle charge condition. Trickle charge condition means the battery
section voltage is too low or the battery section is too cold or too hot to fast charge. If a
battery section’s voltage is too low, or, is too cold (below optimum charging temperature)
to charge, the charger will trickle charge until the voltage or temperature is high enough
and then go into fast charge. If the battery section is too hot, the charger will wait until
the section cools down before going into fast charge.
3.6.3 “90% Charge” Indicator LEDs
The two yellow LEDs labeled "90% CHARGE" indicate when the battery section is at least 90% full
capacity. One indicator is for each section.
If the battery is charging and it is removed and then reinstalled back on the charger, the unit will
restart the charge cycle.
3.6.4 “Discharge” Indicator LEDs
The two yellow LEDs labeled "DISCHARGE" indicate when the battery section is being
discharged/conditioned. One indicator is for each section.
