However, unlike zinc chloride batteries, where the cathode is the inside portion of the battery and the anode is on the outside, the alkaline cathode is on the outside and the alkaline anode is on the inside.
The alkaline cathode is a mixture of manganese dioxide, graphite and an electrolyte.
As with the zinc chloride battery, the cathode and the anode portions of the alkaline battery must be kept from coming into contact with one another.

Recharging these batteries is only effective, however, if the cells have been discharged to less than 50% of their total capacity.
The longevity of the reusable alkaline is a direct function of the depth of discharge; the deeper the discharge, the fewer cycles the battery can endure.

 CIRCUIT2
Although the charging profile for these cells is quite different from alkaline cells, the circuit seems to work fine provided you do not leave them in the charger forever, because of the possibility of overcharging especially for the smaller batteries.
Pulses generated by the 555 are used to drive a dummy load and the AC voltage which develops across the battery gives an indication of its internal resistance: the lower the voltage the healthier the battery.
The internal resistance depends on the battery temperature as well; this is the reason for the switch: hot means a battery (not ambient) temperature between 35 and 52 degrees Centigrade, normal is for a temperature between 16 and 34 degrees and cold is good for a temperature from -4 to 15.

 battery myths vs battery facts - free information to help you learn the difference
The actual or available capacity for a battery is way more important to actual useage but is also more complex to determine, because it really depends on what you are using the batteries for.
Battery capacity ratings are meaningless when used to compare different types of batteries or to compare the capacity of batteries powering different types of devices.
Assigning capacities to batteries can be very tricky, that's probably why you don't see capacity ratings marked on most alkaline batteries.
