The lithium-ion rechargeable battery stores even more power and so, lasts longer in-between charges. With more power, it can also juice up more power-hungry devices, but do you know the 18650 Battery Dimensions & Specifications?

With a stronger power, the drill is able to turn faster and thus, drill harder.

With best rated li-ion 18650 batteries, you do not need to take care in charging as you do with other types of batteries. This is because it is relatively difficult to overcharge the battery. When it has reached its full capacity, its integrated circuit will stop it from being charged further. On top of that, you do not need to discharge the battery periodically even if you do not use it since there is no memory effect.
