Quite often, consumers are unaware of what is powering their laptop computers. When their machine needs charging, they plug it in, usually with the supplied battery pack. Although most users may not consider it important to know, that most battery packs actually contain several 18650 lithium-ion battery cells. In battery terms, these are among the most powerful cells available. Many devices utilize lithium-ion (or Li-ion for short), to supply power. A number of electric shavers for instance contain a Li-ion battery. In terms of voltage, 3.7 is often typical. With a full charge, they'll pack up to 4.2 volts! And yes, these cells are also made very small, sometimes in button form, supplying power to very small devices!
 

The basic rule of getting a replacement battery is that it should have the same voltage as the original. An 18V drill cannot run on a 12V battery. It can only run on a 18V battery. The other thing is that the physical packaging of a battery can be different from company to company. A 12V Ryobi battery may not fit into a 12V Makita cordless drill unless the battery has the right physical dimensions. So make sure the replacement battery looks the same as the old one before you order it. Also, if you are looking for a replacement battery of the same voltage rating and by the same company, know that battery technology is changing rapidly. An 18V lithium-ion battery has a different physical packaging than a NiCad 18V battery.

In fact many experts cobalt mining copyright have tripped over themselves trying to explain it. However, I've heard a graspable explanation of it from an old Chinese battery manufacturer/expert very recently. Which is: The "C Rating" is the number which you multiply to the capacity of the battery to get its discharge rate.

Almost all drills (except for the most inexpensive ones), come with two batteries so that you are able to use one battery while the other battery is charging. Several brands let you buy drills, saws, and other tools separately, without also purchasing batteries and chargers. This can save you money by letting you share both batteries and chargers among multiple tools as you would with a cordless kit.Craftsman and DeWalt are among the brands that let you use lithium cells (a common battery used for many tools) with some of their nickel cadmium tools.
