RODUCT FEATURE
GYSTECH 7000 is designed for charging a variety of SLA (Sealed Lead Acid) batteries, widely used in
cars and several other vehicles. The batteries may be of various types i.e. WET/Flooded (Liquid
Electrolyte), GEL (Gelatin type Electrolyte, absorbed into the plates), AGM (Absorbed Glass Mat)
batteries. Gystech :
- charges 12V batteries (6 cells of 2V) from 14 Ah to 130 Ah, or provides maintenance charge for
12V batteries from 14 to 230 Ah.
- charges 24V batteries (12 cells of 2V) from 14 Ah to 60 Ah, or provides maintenance charge for
24V batteries from 14 to 120 Ah.
It automatically detects the nominal voltage of the battery connected (12/24) (> 7.8 V).

ONNECTIONS
Charging of a permanently installed battery in a vehicle
a- Before connecting or disconnecting the battery leads, the power cord should be removed from
the mains.
b- Check polarity of battery posts. A positive (“+”) battery post usually has a larger diameter than
a negative one.
c- Identify the pole of battery which is connected to the chassis (earth). Normally the negative
terminal is connected to the chassis.
d- Charging of negative earthed battery :
- Make sure the black wire (“-” pole connection) has no contact with the fuel line or the battery.
- Connect the red wire(“+”) to the positive (“+”) pole of the battery and the black wire (“-“) to
the vehicle chassis.
e- Charging of positive earthed battery :
- Make sure the red wire (“+” pole connection) has no contact with the fuel line or the battery.
- Connect the black wire(“-”) to the negative (“-”) pole of the battery and the red wire (“+“) to
the vehicle chassis
