GYSFLASH 20.12/24 PL
The Gysflash 20.12/24 PL is equipped with a function that :
- when charging a lead-acid battery, adjusts the output voltage automatically according to the ambi-ent air
temperature. This adjustment allows for a very accurate lead-acid battery charge adapted to the tempe-
rature.
- When charging a lithium battery, the charge is prevented if the ambient temperature is below 3°C.
In both cases, the adjustment can take between 1 and 10 minutes before the charge starts or stops.

nance charge cycle.
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 20.12/24 PL to be able to charge the battery,
it is necessary to deactivate the UVP protection. To do this, select the Lithium charging mode
