When the hybrid engine is was ist kobalt 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 battery will over-charge if left attached to the charger. The battery stops charging automatically when full lithium facts so it will not over charge. If the battery is left on charge too long it is possible that heat will damage the battery.
ONickel Cadmium (NiCd) - The oldest battery type used in cell phones. They are the heaviest and lowest capacity battery type. These can be somewhat hard to find.
For this cordless drill comparison I decided that the chemical properties weren't important to me. What mattered was why an Li-ion battery may be better than a nicad battery. My drill comparison came up with 2 major reasons. Li-ion batteries weight is about half that of a nicad battery. In other words when you hold a 18 volt lithium bettery stock ion powered cordless drill driver over your head you will notice a major difference in the weight over that of a 18 volt nicad drill driver.
The Makita LXFD01CW Drill didn't stack up to the test as well as the Dewalt drills did. Overall it got a 3.5 out of 5 stars and a few user complaints. One guy commented that the batteries for all of the Makita drills are not interchangeable. You have to have the special 18V battery for this specific Makita LXFD01CW Drill. Yet he said the performance of the drill was outstanding. Another guy commented on the longevity of the drill, he's had it for a long time and it's been very durable. He liked that it was small and lightweight yet powerful enough to handle any task.
