When it gets the battery fully charged,
the “trickle” cycle consumes 1 watt of power more than when the unit is on but no battery connected,
which is roughly 1/14.2 = 70 milliamps “Trickle Current”

It can charge two batteries in parallel.

I wish it had a 90% charged LED too, instead of individual LEDs for 75% and 100%,
or a 1-100% digital readout.


There is a inline fuse on the DC side on the Pulsetech.

I plug in an older, cheaper, Kill-A-Watt power meter on the AC side to watch the watts of power, which smoothly drop as the battery reaches full charge.

I now do this will my older 1970s Schumacher 1.6-2-10-50 amp battery charger too.
