English - Defa Smartcharge 4A Mode D'emploi

8. After charging, power-off the charger
and disconnect from the mains' power
supply. The minus and plus terminals
can then be disconnected.
9. This charger includes high-strength
magnets and should not be placed in
close proximity to magnetic storage
devices such as computer hard drives
and tape media.
Charging phase details
Provide chargers for a variance of vehicles and
equipment such as motorbikes, snowmobiles,
lawnmowers and boats etc.
Battery Type
Lead acid battery (open and closed types),
AGM and Gel batteries included.
Pre Analysis
The charger checks if the battery is correctly
connected. The battery's charge level (V) and
total capacity (Ah) is measured to determine the
correct settings for charging.

Charging
The charger starts charging the battery with
constant current up to 14.4V (at 25°C). The
charge voltage is then held constant at 14.4V and
the charging current is reduced until it is below
a defined level. The charge voltage then drops to
13.8V, before the long-term charging phase starts.
During charging, battery charge is shown by the
number of LEDs illuminated. The blinking segment
above these LEDs indicates active charging. Once
full battery charge is reached, all 5 LED segments
remain illuminated.
If the measured battery voltage is below 2.0V,
the charger will enter Error Mode.
Post Analysis
The charger analyses the battery again after the
charging phase. If the charger detects an error in
the battery, the warning triangle will flash. Post
analysis can detect batteries with a short circuit in
individual cells. This cannot be detected in the pre
analysis. If the battery voltage drops below 12.5V
within 2min, the charger will go into error mode.
The charging sequence will be stopped.
Long-term charging
240 hours after the battery is fully charged, the
charger will go in to Sleep Mode. This is indicated
by all battery LEDs slowly pulsating. This mode
has a very low power consumption.
After a week in Sleep Mode, the charger will
wake up and begin a new charging cycle.
The charger will also wake up and start a
charging cycle if battery voltage drops below 12.6V.
