Each of the 10 individual cells is a cylinder slightly shorter and narrower than a standard AA battery:
standard "Duracell" AA: 2" long, 9/16" diameter
cell in PB battery: 1-15/16" long, 1/2" diameter
The PB battery cells notably lack the little protrusion of the positive end of the battery which AA cells have... the PB battery cells are thus essentially flat on both ends.
The fit of the cells in the case is so tight that I doubt I could make AA cells fit.
The battery also has within it four "devices" in addition to the cells. Each device has two wires, and each device looks different from the others. Does anyone know what these devices are, and what their purpose is?
As you look at the battery, it has 5 contact pads. Here is what I can visually determine to be the connectivity of the devices and cells within the battery:
pad 1 to +cell1
-cell1 to +cell2
-cell2 to device1
device1 to +cell3
-cell3 to +cell4
-cell4 to +cell5
-cell5 to +cell6
-cell6 to +cell7
-cell7 to +cell8
-cell8 to device2
device2 to +cell9
-cell9 to +cell10
-cell10 to pad5
pad2 to device3
device3 to pad3
pad3 red wire to device4
device4 black wire to pad4
No two of the four devices looks the same. Device1 looks sort of like a diode. Device2 is a rectangular metal case (approx 1 mm by 2 mm by 12 mm, with leads coming out of one small end). Device3 looks a bit like a very tiny blue capacitor. Device4 looks a bit like a small black transistor (but only has two leads going to it).
