Any secondary or the non-rechargeable battery including zinc carbon or any dry cell will provide around 500-800 mill-ampere/hour current. As it is obvious that the battery efficiency is highly dependent on the test and the measure condition, is also depends on the duty cycle, cut off voltage.
Considering here one fact that:
• Zinc-carbon and the dry cell are known as general purpose
• Zinc-chloride batteries are known as heavy duty batteries.
The reason being is just that zinc chloride batteries are capable of storing 900-1800mAh Zinc–carbon batteries are usually marketed as "general purpose" batteries. Even any battery other than alkaline battery that is of 2000-3000mAh, costs way high than this zinc chloride batteries.
In a specific scenario like digital camera that are used in present days, where lots of power is necessary and the voltage required is less, key factor is that the battery should last longer. The only significance here to be followed is that the battery should discharge late even with a high cost. In terms of having high open circuit voltage, lithium-iron batteries have in circuit voltage reduced. As lithium based batteries are not compatible to the other zinc-based batteries, voltage levels should be improved. In AA size, rechargeable batteries are available in various chemistries with having rough capacity of 500-900mAh and it is composed of nickel, cadmium, lithium, iron. For more information visit us.
