INTRODUCTION
The LTWI-BATCHG125 is a seven-bay charger for charging the LTWI-BAT50 and LTWI-BAT150 rechargeable
battery packs. It is able to charge up to five Belt Packs and two LTWI-BAT50 rechargeable battery packs either
separately or together. It takes approximately 4.5 hours to fully charge. Using the Belt Pack/LTWI-BAT150 two-
way bays, up to two LTWI-BAT150 rechargeable battery packs can be charged instead of the two Belt Packs.
LEDs indicate the charging status at all times.

LTWI-BATCHG125 BATTERY CHARGER SETUP
Step 1: Plug the DC cable of the enclosed wall-adapter power supply into the 12V DC power connector (#11) on
the rear panel of the LTWI-BATCHG125 unit. Plug the other end of the power code into a standard wall
outlet.
Step 2:.Toggle the POWER switch (#12) on the rear panel of the LTWI-BATCHG125 to power on. Then a green
power LED (#7) should go on. While plugged in, the power LED will stay on.
HOW TO USE LTWI-BATCHG125 BATTERY CHARGER
CHARGING BELT PACKS
1. Ensure that the LTWI-BAT50 rechargeable battery pack is installed correctly inside of the Belt Pack you
need to charge.
2. Confirm that the Belt Pack is turned off. Belt Packs will not be charged properly while the power is on.
3. Put the Belt Packs into the proper charging bays. As shown from the Figure 5, the three ports of (A) are
dedicated stations for Belt Packs and the two ports of (B) are two-way stations for either Belt Packs or
LTWI-BAT150 rechargeable batteries.
4. By docking the Belt Packs or Batteries, confirm that the amber sensing LED is off and the red charging
LED is steady on.

ALERT!
Do not attempt to charge any batteries other than maker designated rechargeable NiMH
batteries otherwise, it may cause damages. If you attempt to charge alkaline battery into the
charger, a red charging LED will be blinking to alert a warning.
Turn off the Belt Pack before charging.
It is necessary to store the battery after fully charged and separating from the Belt Pack.
CHARGING LTWI-BAT50 RECHARGEABLE BATTERY PACKS
1. Put LTWI-BAT50 rechargeable battery packs into the proper charging bays. As shown from the Figure 6,
the two ports of (C) are dedicated stations for LTWI-BAT50 rechargeable battery.
2. Confirm that the amber sensing LED is off and the red charging LED is steady on by docking the battery.

CHARGING LTWI-BAT150 RECHARGEABLE BATTERY PACKS
1. Put LTWI-BAT150 rechargeable battery pack into the proper charging bays. As shown from the Figure 7, the
two ports of (B) are the two-way stations for either LTWI-BAT150 rechargeable battery or Belt Pack.
2. Confirm that the amber sensing LED is off and the red charging LED is steady on by docking the battery.
CHARGING AND SENSING LEDs
The indications of battery status LEDs next to each charging station are as follows;
Sensing LEDs in amber next to each charging station stay on while the bay is empty. When a Belt Pack,
LTWI-BAT150 or LTWI-BAT50 rechargeable battery is inserted properly in each of the relevant bay,
sensing LED of the relevant charging station should go off and the charging LED goes on in red.
If the sensing LED in amber is steady on after a battery is inserted in a charging station, there may be a
defect on either the rechargeable battery pack or LTWI-BATCHG125 battery charger. The issue may be
detected with the following tests;
Try to put the relevant battery pack ‘A’ into other bays. If the amber sensing LED is steady on, try to put
another battery pack ‘B’ into the same bay. If the amber sensing LED goes off and red charging LED
goes on, it indicates that the battery pack ‘A’ is faulty. If the amber sensing LED is still steady on when
the battery pack ‘B’ is inserted, it indicates that the LTWI-BATCHG125 battery charger is faulty.
When a battery is in a bay and the sensing LED flashes in amber, it indicates that the battery is too
“HOT”. In this case, please remove the battery from the charger and cool it down.
NOTE: When the amber sensing LED blinks, the battery charger will quit the charging automatically. The
LED keeps blinking if the battery is not removed.
When a battery ‘A’ is in a bay and the charging LED flashes, it indicates “Failure to charge”. It may
happen when either the rechargeable battery pack or the LTWI-BATCHG125 battery charger is faulty.
Retry it in a different bay by using the same rechargeable battery pack ‘A’. If “Failure to charge” happens
again with the red charging LED flashing, put another battery pack ‘B’ into the same bay. If the new

battery ‘B’ works well, it indicates that the rechargeable battery pack ‘A’ is faulty. If the new battery pack
‘B’ fails in any bay the same, it indicates that the LTWI-BATCHG125 battery charger is faulty.
NOTE: When the red charging LED blinks, the battery charger will quit the charging automatically. The LED
keeps blinking if the battery is not removed.
A charging LED next to a charging station is steady red on while a rechargeable battery pack in the bay
is being charged. The charging LED turns to green when the rechargeable battery pack in the bay is fully
charged.
NOTE: Make sure to remove the battery, once the battery is fully charged with the green charging LED on.
The battery charger will quit the charging automatically, once fully charged.
NOTE: Rechargeable AA-size NiMH (nickel-metal hydride) batteries are used in LTWI-BAT150 and LTWI-
BAT50 rechargeable battery pack. Like all rechargeable batteries, LTWI-BAT150 and LTWI-BAT50
rechargeable battery pack have the limited charging cycles. The battery life and charging capacity
are greatly depending on the usage, storage condition and etc. It is recommended to replace the
battery every six months when using them under certain circumstances. The battery status can
always be monitored from the front panel display of the Belt Pack and Base Station. The battery is
fully charged but if the status bar tends to drop quickly down, it may be time to replace the battery to
new one.Also, extensive over-charging may damage or shorten the battery life.
To detect “Failure to charge”, the LTWI-BATCHG125 battery charger monitors the battery’s voltage,
temperature and time under charge. Any of these conditions may cause “Failure to charge” of the
battery charger. To detect “HOT” status of batteries, the LTWI-BATCHG125 battery charger monitors
the thermal sensor in the rechargeable battery pack. If the battery is in “HOT” status, the battery
charger quits the charging automatically.
