Since cordless power drills don't require an external power supply, they are portable and can be used in outdoor areas without having to bring a generator. The absence of an attached power cable means users can manipulate battery powered drills safely without worrying about tripping or pulling on other objects. The small size of cordless drills also makes them convenient for use in tight spaces and corners.
Drill battery voltages must match the voltage rating of the power tool (be it cordless hammer drills, impact drills, or driver drills) for maximum efficiency and safety. Voltages range from 6 volts to 18 volts and above, with lower voltages being sufficient for light work and higher voltages suited for heavy-duty drilling of tough material. Be sure to stock your shop with batteries of different voltages to appeal to users ranging from hobbyists with 7v entry-level drills to professionals with 20v cordless drills.
Cordless drill batteries may be made from NiCD (nickel cadmium), NiMH (nickel metal hydride), or Li-Ion (lithium ion) (from oldest to newest). The best battery type for cordless power tools depends on the tool's function. NiCD batteries are suitable for intensive, regular power tool use over a long time, but are heavy, suffer from memory effect, and pollute the environment. NiMH batteries are safer for the environment and much lighter than NiCD batters, but are less durable. Li-Ion batteries are the lightest, discharge relatively slower, and do not suffer from the memory effect. That said, they are more fragile and not as durable as NiCD batteries. Battery types and chargers cannot be mix-and-matched. On Alibaba.com, you can browse for suppliers selling compatible chargers for the cordless driver drill battery types you intend to sell.
Battery storage boxes are a necessity for battery operated drill owners. Users often own spare batteries to ensure they don't run out of power during a job, and a storage case makes finding and carrying the spares easy. A good case prolongs battery life by storing them safely at cool temperatures, moderate humidity, and protection for battery terminals which should not be exposed to each other or other metals.
