If you're going to purchase a cordless tool, then you should really think about getting one with Lithium ion batteries. They cost more, and it's easy to think you could just buy a cheaper model and get a spare battery, but it's not the same. Lithium ion batteries are a true hassle free solution.
 

When the hybrid engine is lithium ion battery stocks in parallel both engines can propel the car alone or together. A good example would be Toyotas' Hybrid Synergy Drive (HSD). Capable of being propelled at low speeds by the electric motor, the gas engine takes over at higher speeds. This allows both engines to perform in their optimal situation.

The type of gloves you buy will depend on what you'll be doing when you're wearing them. If you plan on taking part in an activity then the gloves should be flexible to give your hands the freedom of movement they need. You don't really want a big bulky pair if you need to lithium facts pick things up or get a fine grip in them. A thin pair would be better suited in these situations.

Hybrid cars tend to come with several things. Regenerative braking helps restore power to the large battery packs necessary for the electric motor (more on that later). Some people claim that the regenerative braking makes the braking feel different.

The mating lithium bettery stock process between the two engines can be in series or in parallel. When the two powertrains are mated in series, only one of the motors controls the cars movement. The other one simply assists the first, dominant engine. This occurs most often in mild or assist hybrids. The Saturn Vue Green Line Belt Alternator System (BAS) is a good example. The concept vehicle named the Volt from GM is another good example of a series (but not a mild) hybrid.

All power tool batteries degrade over time and lithium ion batteries degrade more rapidly over periods of un-use. Accordingly, use them often and when you're not in the trenches of a project, try to use them at least once each month.

For jobs where the batteries are required to be light weight as well as being reusable, then lithium batteries are ideal. But if a battery is needed to be very reliable or to remain unused for a long time then they might not be the right batteries for it.
