Dry cell is a voltaic cell, using some absorbent (such as wood chips or gelatin) will not spill the contents to become a paste. Often used as flashlight lighting, radios and other power supply.

Many people hope that from an economic point of alkaline batteries can be reused, situations where such could not be better. However, alkaline batteries can recharge your batteries? Because alkaline batteries are classified into primary batteries, but also a battery, in this sense, the alkaline battery can charge it?
The answer is yes, alkaline batteries can also be charged, but there are many technical problems, such as high current charging cases, alkaline batteries can recharge your batteries?
Article below 0.1C charging member, the alkaline rechargeable battery 20, but which is different from the secondary battery charging process. Under normal circumstances, they can only be charged in a partial discharge is impossible, as the rechargeable battery as the real depth of discharge is charging.
Alkaline battery is only partially charged, this approach will generally be referred to as "regeneration", "regeneration" concept further illustrates the alkaline battery charging feature: Alkaline batteries can recharge your batteries? Can, but it is the regenerative charging, unlike the real battery charge.
Reproduction limitations and short charging and discharging cycle life of alkaline batteries determines regeneration is very economical. To ensure the successful regeneration of alkaline batteries, Article must meet the following conditions:

1 in the case of moderate discharge rate of the battery discharge initial capacity of up to 30%, while the discharge should not be less than 0.8V, regeneration is possible. When the discharge capacity of more than 30%, the resulting manganese dioxide prevents further regeneration. 30% of the capacity and the discharge voltage of 0.8V by suitable devices, but these devices are not most consumers. Most ordinary consumers at this case, alkaline batteries can recharge your batteries? This is not an economic problem, but Article pieces of the problem.
(2) the user can purchase a dedicated charger to regenerate. If you use other chargers, alkaline batteries can recharge your batteries? Security risk is too great, under normal circumstances, nickel-cadmium, nickel-metal hydride battery charger can not be used as alkaline manganese batteries, because this charger charging current is too high, it may cause the battery internally generated gases, if the gas impulse the valve will leak. Still further, if the valve out of action, or even explode. Such as in the production of molds bad this rarely happens, but it will happen, especially without the proper use of batteries.
3 the time required for regeneration (about 12 hours) in excess of the discharge time (about 1 hour).
4.20 cycles the battery's capacity will be reduced to 50% of the initial capacity.
5 requires three or more special equipment connected to the battery, if the battery capacity is not, then there will be other problems regeneration, which may cause the battery voltage to a negative value if the reproduction of the batteries and used batteries together without Use will be more dangerous. Battery reversal resulting hydrogen inside the battery has generated high risk, resulting in leakage or explosion. Without batteries also have a good consistency three cases, alkaline batteries can recharge your batteries? Obviously unnecessary.
A primary battery for a long time reproduction only uneconomical but also risking a certain risk, and if so, "alkaline batteries can be charged and it" is not a technical problem. In order to avoid danger, it is best not used with a battery or a secondary battery (batteries) do not regenerate once the battery.
