WP6 Charger
The charger was launched in 2010 and designed as a CC/CV charger. It features six independent channels, allowing it to charge six batteries simultaneously and independently.
The charger is powered from a single 12 volt DC connector, this connector can be powered from either the supplied AC adapter or from a car adapter. The AC adapter I got is a universal voltage adapter (100 – 240 VAC 50/60 Hz) with a plug for European use.
There is a led for each channel, this led will be red when the charger is charging and green when finished.
Measurements
The charger uses around 100mA charge current for batteries below 2.8 volt.
Between 2.8 volt and 4.2 volt the charger is applying regular charge current (See curve below).
When the battery goes above 4.2 volt the current is turned off (below 4uA current).
The charger will not restart charging before the battery has been removed or the voltage goes below 4.08 volt.
When charger is disconnected from power, but with a battery in, it will draw below 1uA from the battery.
More batteries will not change the charge current.
Because each channel is independent, the different voltage varies between the channels. I measured the 4.2 volt to vary between 4.18 and 4.22 volt.
