It makes sense to use alkaline batteries
Alkaline batteries have a long shelf life and do not suffer the memory effect of nickel-cadmium batteries. The effects of the term "memory" refers to the batteries getting weaker with continued use, especially when the batteries have been set up and use do not respond well to additional charges. The problem stems from low battery flows derived from only a small part of the active area of the cell anode. If higher current had been drawn or if the battery is completely discharged, the entire active area of the anode have been involved. The unused area essentially "films over and acts as a barrier to current flow. Moreover, the burden does not restore the active zone.
Alkaline batteries self-discharge. This is a chemical change that causes degeneration of the electrodes of nickel-metal hydride and nickel-cadmium batteries. Reversible to load and unload several times. The batteries are charged before use does not provide the total amount of stored energy. None of the above happens with common alkaline batteries. The self-discharge rate of nickel-cadmium is about 2% dell adapter per week, in nickel-metal hydride is approximately 3% per week. At temperatures above room temperature, these growth rates.
What about alkaline batteries designed for recharging?
Paradoxically, these higher-priced special batteries, known as RAM batteries, or rechargeable alkaline manganese, are not highly valued in technical reports. Some journals are displayed as rechargeable for only 25 to 30 times maximum. Not expected when used in high drain applications like digital cameras, as the voltage supplied by the battery down in response to current high demand. A representative battery sales refers to the RAM memory cells as 'mild' batteries. (The company made piles of RAM in time, and still no).
Is it difficult to recharge a normal alkaline battery?
Very difficult if you do not have the type of equipment designed to do the job. We have been saying for a safety test, the journal of the trust that has existed for years, and will remind you again at the end of this chapter. Using the wrong type of alkaline battery charger can be downright dangerous. Just read the warning labels printed on ordinary batteries. NiCad charger should never be used in alkaline batteries. This charger to provide power over certain values, not turn off automatically when the battery voltage exceeds safe limits, and will continue unchecked until the battery is damaged.
