HOW TO USE
Start your vehicle and let it idle.
And the charger will recognize that there is a charge being applied to the main starting battery.
The charger will charge the auxiliary battery when the main starting battery has reached 13V (ACC
line not connected).The main battery will start charging the auxiliary battery when its voltage is or above
11.5V (ACC line connected).
Press “POWER” to re-select batteries (The default setting is for lead acid battery, and your setting will
be saved once selection is made).
The charger will continue to operate even after the vehicle has been switched off, however when the
main starting battery falls below 12.5V the charger will automatically shut off (ACC line not connected).
When the main starting battery falls below 10.8V, the charger will automatically shut off (ACC line
connected).
Note: When the voltage drops to 13.2V for LiFePO4 battery/12.3V for AGM, Gel & Calcium after
a full charge, a recharge will begin.
Wake-up of Lithium-Ion Batteries in Sleep Mode: this DC-DC charger cannot charge a lithium-ion
battery in sleep mode. To charge the lithium-ion battery, first make sure the DC-DC charger is
correctly connected to the battery. Then select the “LiFePo4” mode, and long press “POWER”
for 5s. The “charging” (red) indicator will flash for 10s. If the battery is successfully waken up,
the “charging” (red) indicator will be constantly on and the DC-DC charger begins to charge the
battery. Otherwise, the DC-DC charger will enter the standby state and the “Power On” indicator
will be on.
DEEP CYCLE BATTERY MAINTENANCE
This DC-DC charger by ATEM POWER will be used to charge your auxiliary battery, for example, deep
cycle batteries that are designed to provide power for your fridges and light in caravan or camper.
Your fridge might use appropriately 24AH per day. In this light, if your 100AH battery is only used to
power your fridge while receiving no charge, and it would require charging after 48 hours.
To replenish the capacity of the battery (100AH capacity, 50AH discharged), you may need to use a 40
amp DC-DC charger that would further require at least 1.25 hours of driving/solar charging. A 30 amp
unit will require at least 1.67 hours of driving/solar charging to fully recharge the battery. A 20 amp unit
will require at least 2.5 hours of driving/solar charging to fully recharge the battery.
