Most batteries today are Lithium Ion batteries. They do not suffer memory loss like the old nickel hydride batteries did. This happened when you would charge the battery when it was only 1/2 down and after awhile, it believed that 1/2, was empty. With Lithium Ion batteries, we generally advise that you charge them for 8-12 hours before use, but this is purely precautionary. I would definitely take the phone in to the retail store and advise them that you believe the battery is bad. I would guess they can either test and/or replace your battery. By the way, on most modern PC's the time is updated from the web. The 3V battery just maintains the time when the PC is powered off. This is useful as the motherboard clock is not very accurate, easily losing a couple of minutes per day. VSR stands for variable speed reversible. These drills come in both corded and cordless versions as will most all the drills we discuss from here on out. The drill speed is varied by the amount of pressure applied to the trigger. The farther the trigger is pulled, the higher the RPM will be. There is also a switch, usually near the trigger which reverses the operation of the drill. As you can imagine, these have distinct advantages over the basic corded drill. In addition to being able to perform all the functions of the basic corded drill, they also have a better suited although still limited ability to drive screws, and small lag bolts. Since the speed is variable, you have the ability to drill into harder material without overheating the bit. lithium bettery stock You can also choose from a beeping alarm or radio alarm. I prefer the radio because the songs and DJs are more likely to wake me up. However, the radio tuner is only analog, so if you don't know the frequency of your favorite radio station, you might have a hard time tuning it. Otherwise, the radio and alarm work perfectly. lithium facts Nickel-Cadium - Ni-Cd batteries is one of the oldest and best performance types of rechargeable batteries but it has a major problem. After a long usage ( a few years), the battery will suffer from the dreaded memory effect. This means that the lifespan usage of the battery will deteriorate as time goes by. ONickel Metal Hydride (NiMh) - Popular battery about 1-2 years ago. They are lighter than Nickel Cadmium batteries, but heavier than Lithium batteries. lithium ion battery stocks should be cycled once in a while for optimum performance. lithium stocks canada All you need is two batteries. Put one battery into a quick charger to charge while working with the other battery and repeat the process as long as need be. Lithium-ion technology battery life is undetermined, however, the eight year 100,000 mile warranty on the Chevrolet Volt and the Nissan Leaf do give some piece of mind.
