CHARGE MODES

• Modes and Options description:
CHARGE mode (14.4V / 8A-12A):
Mode designed to charge and maintain (floating charge) 12V lead-acid batteries. 8 steps automatic maintenance
cycle.
SUPPLY Mode (13.6V/7A):
This mode enables to use the charger as a stabilised power supply, with a voltage regulated at 13.6V. This mode is
designed for providing a power supply to demonstration vehicles and can also be used to replace a vehicle's battery
while maintaining the system's memory. With this mode, there is no time limit.
When the
current absorbed by the battery is higher than the charger's maximum current (8A or 12A) and that the battery might
end up being discharged.

• Charging curve:

The GYSFLASH 8.12 and 12.12 use an 8 steps charging curve which guarantees optimal performance for your battery.

GYSFLASH 8.12 / 12.12
COLD/AGM or AGM Option (14.7V):
Modifies the charging voltage at 14.7V for some AGM batteries or batteries with caps. For the Gysflash
8.12, this option allows to charge the battery during cold weather (Less than 5°C).
REFRESH Option (15.8V):
Option which add an extra step (step 7) to the charge cycle to restore deeply discharged batteries.
: this option is not recommended for charging sealed batteries.
Recommendation: Check the battery's water level and if necessary, perform with a Refresh charge.

Constant voltage charge to reach a 100% charge level.
7
Step : Refresh (option 15.8V)
If the refresh option has bene selected, the charger will inject an
additional current that will generate some gas, thus recondition-
ning the battery's cells. During this phase, the battery may loose a
bit of water.
