Green Digital Power-tech G10-XXN User manual

CAUTION
1. SAVE THIS INSTRUCTIONS- This manual contains important safety and
operating instructions for the G10-XXN battery charger.
Please read the caution ofbatteries or devices you want to charge firstly!
2. When charging, batteries can emit explosive gases, therefore it is essential to
prevent flames and sparks. The charger is designed for charging specified
NIMH/NICD batteries. Do notuse for any other purpose.
3. Always provide good ventilation when charging.
4. Use of an attachment not recommended or sold by Green-Digital Power-tech
may result in a risk of fire, electric shock or serious injury to persons.
5. To reduce risk of damage to electric plug and cord, pull by the plug rather than
by the cord when disconnecting charger.
6. An extension cord should not be used unless absolutely necessary. Use of an
improper extension cord could result in a risk of fire and electric shock. If
extension cord must be used, make sure that: a) Pins on plug of extension
cord are the same number, size and shape as those of plug on charger; b)
Extension cord is properly wired and in good electrical condition; and c) Wire
size is large enough for ac ampere rating as specified in “technical data”.
7. Do not operate charger with a damaged cord or plug-return the charger to the
place where purchased.
8. Never operate the charger if it has received a sharp blow, been dropped or
otherwise damaged in any way; take is to a qualified serviceman.
9. Do not disassemble the charger; take it to a qualified serviceman when
service or repair is required. Incorrect reassembly may result in a risk of
electrical shock or fire.
10. To reduce risk of electric shock, unplug charger from AC outlet before
attempting any maintenance or cleaning. Turning off controls will not reduce
the risk.
G10-XXN 4.8V~12V NIMH/NICD Battery Charger

Brief Introduction
G10-XXN is a main member of digital-chargers from Green Digital
Power-tech Co., Ltd. It represents today’s new technology for 4.8V(4s) ~
12V(10s) NIMH/NICD battery pack charging. G10-XXN programmed 2 auto
stages ( Im-It) charging process，It is designed for 4s(4.8V) ~ 10s(12V) 2~8Ah
NIMH/NICD battery pack. When the battery was connected properly, stage “Im”
will give bulk constant current charging. This is the main charge stage, when
the battery nearly charged full , -dV phenomenon will be detected by the MCU
in charger (-dV value is 3~6mV/per cell about) . Then the battery will leave bulk
stage and cut-off output or enter a defined trickle pulse charge stage “It” to
maintain battery.
Further, G10 can display the charging process, indicate the battery
capacity from 50% to 100% timely. This is helpful for user.
For more safety, G10 will inter protection mode when the battery polarity
reversed our the output connectors shorted.

How to use:
1. Connect theAC cord tothe socket, The “power” lamp will light on RED.
2. Connect positive charger clip (red) to positive battery terminal, the black clip
to negative. (You can use other dc plugs to connect battery), the
“50%~100%” lamps will light on flowing. If the battery polarity reversed or
output shorted, 3 lamps willflashing, please check the setup.
3. Depend on the charged capacity, 50%~100% lamps will lights up solid
sequence, until the battery is fully charged. Then you can power off the
charger and disconnect the battery or you can charge a new battery if you
need.
The table shows the durationof 100% state charged for an empty battery.

All 3 lamps flashing means battery
polarity reversed or output shorted.
All lamps are “off” means no battery.
