Stationary Charger
for Battery Forklifts

JBY Series Battery Charger
designed in JapanO u t li n e

Traction batteries for forklifts are operated under very hard conditions and the operation pattern isusually irregular. Usually the charging of batteres is performed during the night time, whereby
supervisor cannot be present.
Sometimes the batteries may not be charged
properly, thereby it causes an overcharged orundercharged batteries. GS YUASA batterychargers JBY type have solved the problems.
They were designed on the basis of many
years of our research and experience to assureautomatic charging in proper, efficient way, thus
dispensing with otherwise troublesome battery
charging work.
Let JBY battery chargers for battery forklifts
help you.

Fe at u re s
High reliability and efficency
・Most popular charger with highest reputation by
Japanese forklift manufactures.
・Excellent cost performance by simple structure.

Most suitable electric circuit for
traction batteries
・Can charge the batteries within 8 hours even if they
were discharged 100% (include gassing process).
・JBY charger can withdraw the performance fromthe batteries to the maximum from the batteries
and makes the battery life long.

Easy operation

NO attendance required

・Only press the button once for starting. Thecharging process is indicated by LED lamps incontrol panel.
・NORMAL CHARGING or EQUALIZED CHARGING
can be choosen by pressing the button once.

・Automatic charging system eliminates the necessityof attendance.
・Regardless of the state, the batteries can be fully
charged by JBY charger automatically.
・Even if power failure occures less than one hour
during charging the charging will resume from thepoint of interruption.

＊Equalized charging is strongly recommended once a month inorder to prevent undercharging, however, the excess of it cause
overcharging and might make the battery life short.

Fig.1 and Fig.2 show the output characteristic of
the charger, and the example of the charging curve.
Big current flows in early stages of the charge, at
this time the state of voltage is low.
As the charge proceeds, the current decreases
automatically and the voltage increases.
The current drops by 25% at the end of thecharge.
The drop of current avoids an increase intemperature of the cells at the end of the charge.
When the charger catch the voltage of T point,
the timer starts and the charger stops automaticallywhich the charge becomes enough.
The charger charges safely and perfectly without
damaging any cells.
