In the case of battery drill has the technology to date that a species that are comparable in power to find their cousins ​​over increased, because of advances in batteries, and many are also readily available with prices suitable for all budgets.

If you're a certain age probably remember that the wireless power went, took what seemed an age to be calculated and are difficult to start.

Mainly due to advances in battery technology, companies more and more people are using lithium-ion battery for these portable devices have an advantage over Ni-MH (Ni-MH) and Ni-Cd (nickel cadmium) are

Lighter
5 times lower self-discharge -
Offer long-term time
It offers up to 2.5 times more charge Ni-Cd

Research also indicates that they are not what a memory effect, which means in simple terms, if you do not charge lithium-ion battery at full capacity, but still not to use a full charge , which is known far and pain free again and then the next time you want to use, the battery "forgets" how to use the 100% free and works as soon as possible. This does not work with lithium-ion batteries because of how they are to be made.

When choosing a cordless drill, there are some indicators to monitor

Li-Ion - The last type available, they tend to be easier. It may be more expensive because of the high cost of production.

Ni-MH - offer long-term

Ni-Cd - One of the most common types in the elderly and power tools. They are known to suffer from memory effect of the above and ensure to the best of times they have.
