GENERAL INFORMATION
This sophisticated switch-mode
charger has been specially developed for
use with all deep-cycle sealed lead-acid
batteries including “Dryfit” gel
batteries. It is light-weight, compact
and efficient. It will operate on any AC
input voltage between 90VAC to
260VAC - this means it will work
ANYWHERE in the world without an
additional transformer or switching for
the 1208. It automatically charges,
without requiring monitoring, all sealed
lead-acid, maintenance type and gel
batteries with a nominal voltage of 12
volts. Charging begins immediately if
the battery has been properly connected.
The output of the charger is
electronically protected against short
circuit, reverse polarity connection and
extremely deeply discharged batteries. A
green Light Emitting Diode (LED) on the
front panel is used as a charging and
state of charge indicator.

OPERATION
Plug in and switch on charger at the mains supply and then turn the charger’s POWER
switch on -- the charger is ready for connecting to the charging socket and/or batteries.
IMPORTANT! This type of charger must be switched on before connecting to batteries. When the
charging process begins, the green LED illuminates. After reaching approx. 80% charge, the green
charging LED will cease to glow, BUT LEAVE BATTERIES CONNECTED UNTIL READY FOR
USE. To check that battery is fully charged, turn off AC power or remove the charging connector for
about 30 seconds then re-connect. The green LED should light momentarily then go out again. On
this type of charger the battery may be left connected indefinitely as overcharging is impossible.
