Mode designed for lead-acid batteries, 12V from 1.2 Ah to 15Ah. 7 step automatic maintenance cycle.
CHARGE mode (14.4V/4A) :
Mode designed for lead-acid batteries, 12V from 15 Ah to 90 Ah and up to 130 Ah for floating charge. 7 step automa-
tic maintenance cycle.
COLD/AGM Option (14.7V) :
Modifies the charging voltage at 14.7V to charge the battery during cold weather (Less than 5°C) or for some AGM
batteries or batteries with caps.
SUPPLY Mode (13.6 V/4 A):
This mode enables to use the charger as a stabilised power supply, with a voltage regulated at 13.6 V. 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
rent absorbed by the battery is higher than the charger's maximum current (4 A) and that the battery might end up
being discharged.
