The servo motors are usually powered by batteries. This power source is then regulated to 5V (using voltage regulator). Amount of voltage depends on applications needed. 5V voltage is enough to drive torque to perform useful motions. Commonly, servo motors are powered by smaller batteries like Nickel Cadmium ('NiCd') or Nickel-Metal Hydride ('NiMh') or even the latest; Lithium Polymer ('LiPo').
ONickel Metal Hydride (NiMh) - Popular battery about 1-2 years ago. They are lighter than Nickel Cadmium batteries, but heavier than lithium batteries. These should be cycled once in a while for optimum performance.
Bosch GSR 10.8 V-LI is a small handy and powerful drive drill. The small size makes cobalt mining copyright the drill appropriate for driving screws in machinery. There is limited working space in machinery but with Bosch GSR 10.8 V-LI, one is able to comfortably and accurately drive screws in its parts. Being small and light allows the user to work with the tool for longer hours without fatigue. This in effect leads to early completion of the project.
Specifically however, 18650 lithium-ion batteries are larger both in length and width than standard cells. The numbers, 18650, refer to length and overall circumference. Like most rechargeable cells, their power is rated in milliamp ere-hours (mAh). These mAh designations are often numbered such as 2200, 2400, 2600, 2900, and 3100, which all relate to amount of energy. The higher the number, the more power the battery possesses.

There is also a lot of misinformation about batteries in general based on the older models and technology. You do not need to totally drain the new lithium models. Its fine to use it until you get a warning of low power but don't purposely try to push it to empty since there is no reason to do so now. And if you do push it to absolute no power you might also experience some lose of data, a very good reason not to go that route.
Lithium Ion and Nickel Metal Hydride are the two cordless drill battery types. The latter of the two is the cheaper version, so it's probably best to avoid drills with these batteries. They tend to have memory issues, and fixing it requires a complete discharge before charging them again. If you don't do this, the battery will lose it's capacity to charge. Also, the Lithium Ion batteries will last a lot longer and provide more power.
