User’s Manual
August 2019 First Version
CAUTION
1. SAVE THIS INSTRUCTIONS- This manual contains important safety and
operating instructions for the GA6012 batterycharger. Please read
the caution of batteries 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 lead-acid batteries from 4 to 100Ah. Do not use for anyother purpose.
3. Good ventilation when charging.
4. Use of an attachment not recommended or sold by us may result in a risk of fire,
electric shock or serious injury to persons.
5. To reduce risk ofdamage 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;
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 anyway; take it 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 electricalshockor fire.
10. To reduce risk of electric shock, unplug charger from AC outlet before
attempting any maintenance or cleaning. Turning off controls will
reduce the risk.

Brief Introduction
GA6012 is a new member of a family of professional charger in our
company. It represents today’s new technology for lead-acid type battery
charging. Programmed four auto stages ( Pre-charge, repair or normal
charge-trickle-pulse maintenance) charging process，It is designed for all
kinds of 12V 4~100Ah lead-acid battery, such as SLA, AGM and Gel battery.
Charging instructions：
Connect battery to detect voltage firstly. When battery voltage is less
than 11V, it enters pre-charge mode. Half an hour later, if the voltage is still
below 11V, it enters the repair mode(Repair). (Repair time is 24H, if 24H later
the battery voltage is still less than 11V, It is recommended to replace the
battery, if it is higher than 11V, enter the main charging mode); When
charging current is less than 0.5 A, it enters trickle, (at this time percentage
bar display 100 %, and charge full(FUL) display). When trickle current is less
than 200mA, charger will cutoff completely. After charging cut off, the
battery voltage is detected every 2H. If the voltage is less than 13V, charger
will pulse the battery to recharge.
