CHARGE MODES
• Modes and Options description :
Lead CHARGE mode (14.4 V/1 A) :
Mode for charging 12 V lead-acid batteries from 2 Ah to 32 Ah and up to 100 Ah for charge support.
Automatic seven step charge cycle.
COLD/AGM option (14.7 V/1 A) :
Option to change the charging voltage to 14.7 V for battery charging in cold weather (less
than 5°C) or for some AGM batteries or batteries with plugs.
Lithium CHARGE mode (14.4 V/1 A) :
Mode for charging 12 V lithium batteries from 0.5 Ah to 20 Ah and up to 50 Ah for charge retention.
Automatic charging cycle in eight steps.
Some Lithium batteries incorporate a UVP protection (Under Voltage Protection) which
disconnect the battery in case of deep discharge. This protection prevents the charger from
detecting the battery. In order for the Gysflash 1.12 PL to be able to charge the battery, it is
necessary to deactivate the UVP protection. To do this, select the Lithium charging mode and
press the button
for 10 seconds. The charger will then deactivate the UVP protection
and automatically start charging.
• Load curve Lead:
The GYSflash 1.12 PL uses an advanced 7-step lead charging curve that guarantees the optimal performance of your lead battery.
