Technical Data
*Back Current Drain: Back current drain is the amount of current
drawn by the charger from battery, when the charger is connected
to the battery, without power cord connected. This charger has
extremely low back current drain which corresponds to 0.7 Ah per
month (1mAIhr).
**Ripple/Low Noise: Ripple refers to interference of current and
voltage. A high current ripple heats up battery and reduces life of
battery.
Against a linear charger, which has a current ripple of up to 400%,
the charger's current ripple is below 2%. Consumers connected to
the battery could be damaged by high voltage ripple.
***Ambient Temperature: At ambient temperature output power will
be reduced.
