ONICD Batteries These are the oldest type of kobalt abbau cell phone battery and as is the case with the laptop computer are less reliable than the newer types.
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.
All the phones now come with lithium ion batteries and charging should not be an issue ...although it's best not to charge them over 24 hours..Overnight every night is fine...they all do have a life though leaving it off when you don't need it can extend that. Although you would miss calls.
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.
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.
The bottom line, be gentle to your lithium-ion batteries. If you excessively charge the battery, with high voltages, and heavy load conditions, it will shorten your battery's life. It's best to charge at a slower rate.
