Lower left there are four parallel power supply channels using four coils two hidden under the metal shield. I cannot see well enough with the unaided eye to diracell such detailed work.

See terms – opens in a new window or tab. This causes a negative difference across the comparator and forces its output low. Tom Chichester Level 3 Expert Answers.

Get the item you ordered or get your money back. The comparator is configured to provide positive feedback using a 2. Current measurements are difficult.

Take a look at the marked up board below: This item may be a floor model or store return that has been used. Therefore almost any voltage differential between the AA and AAA posts trips the comparator and flips the circuit into low current mode?

As I write this I think I might have a different meter with a max hold setting. Your opinion is valuable.

I have circled my picks in the image below. I noted that a Rayovac Hybrid reached a maximum voltage of 1.

When an AA cell is being charged the AAA pad will be at equal potential and the voltage difference will be zero. To have the charger put out a mA current, I suspect it would be as simple as configuring the outputs to put out a logic “LOW” pins 1, 2, 13 and What this means is that when current flows through the 0.


Watch list is full. However, when I follow the circuit traces that does not seem to be the case. This is an original See full item description. There is some measure of intelligent control going on in this charger.

Perhaps this is done out of some strange idea that consumers are going Have you looked in the manual? Duracelll my theory is right it will take about 2 hours to charge and will then terminate on cue.
