Currently, the electronics require a large amount of energy to operate. And to meet this voracious consumption, nothing more practical than a dry batteries and batteries charger. When the energy ends, you simply take your rechargeable dry battery and put it in the charger and that’s it: it is ready to be used again. In addition, rechargeable dry batteries last more than common dry batteries -from 2 to 4 times. And they have been developed to be used in equipments such as digital cameras, some GPSs etc..
What are the kinds of charger?
There are various types and capabilities in the market. The charger is connected to the type of batteries for which it was designed. Most of the dry batteries are rechargeable NiMH (nickel-metal hydride). Until recently, it was also common in NiCd batteries (nickel-cadmium). The NiMH offers a much larger capacity, and it can be found in both small size (AA) and (AAA).
What is "mAh"?
"MAh" means miliampére-hour. It is the rechargeable battery unit’s capacity. The higher the mAh, bigger is the duration time of the load. Currently it is possible to find batteries with more than 2,000 mAh.
How do I choose a charger?
The correct choice of the charger is very important to the health of rechargeable batteries. It must be compatible with the carrying capacity of the battery. Give preference to the acquisition of the charger / battery together, as a charger with different time load cell can damage it.
How many times can a rechargeable dry battery be recharged?
It depends on how it is used. If you wait it is completely unloaded before recharging again, the number of refills total will be much greater. Intermediate recharges decrease this number. Typically, these batteries can be recharged at least hundreds of times. In the market, currently, you can find batteries with a life span of more than 1,000 recharges.
Is it cheaper to use a dry battery charger?
Yes, especially the medium and long term. When the charge of a common battery ends, it is not useful anymore and you can throw it away. A rechargeable battery is different: it can be used hundreds of times and guarantees an excellent cost-benefit ratio.
