Thread Tools Show Printable Version. The AAA cell took about 5 hours to charge as normal. Perhaps this is done out of some strange idea that consumers are going For instance negative input 2 at pin 6 orange appears to connect to the Durracell cell and positive input pin 7 red to the AAA cell.


Have a manual for Electronics – Ce21 Related to temperature sensing the CEF21 has a temperature sensor tucked inside each negative post right where it touches the battery and far away from heat generating components in the power supply.

When an Druacell cell is being cf21 the charging current will pass through the resistor producing a voltage drop of mA x 0. Seriously good battery power here – the copper top Duracell 2 AA rechargeable batteries.

Have one to sell? It would be appealing to think this is to prevent the overcharging of a fully charged cell, but I think perhaps it is more likely to reject an alkaline cell that might be placed in the slot. Duracell Alkaline D Batteries. Seller assumes all responsibility for this listing. Duracell CEF21 disassembled modifications, anyone?

This latter voltage matches exactly what I observe from Eneloops and not from any other cell I have tested. Then pinch each iron on either side of the two ends of the surface mount 10K resistor and lift simultaneously.

There is some measure of intelligent control going on in this charger. All times are GMT I’m beginning to think the resistors are just connected in series in the AAA charging circuit as current limiting components.
