Until new nano lithium technology comes in later in 2009, mobile phone batteries are still notoriously flaky. Just when you need to make an important call the battery indicator tells you the charge is all but extinct. You may have conditioned your battery in line with all of the advice and old wives tales floating around but still have to re-charge yours every day. Short of buying a spare and keeping that charged what can you do?
The basic rule of getting a replacement battery is that it should have the same voltage as the original. An 18V drill cannot run on a 12V battery. It can only run on a 18V battery. The other thing is that the physical packaging of a battery can be different from company to company. A 12V Ryobi battery may not fit into a 12V Makita cordless drill unless the battery has the right physical dimensions. So make sure the replacement battery looks the same as the old one before you order it. Also, if you are looking for a replacement battery of the same voltage rating and by the same company, know that battery technology is changing rapidly. An 18V lithium-ion battery has a different physical packaging than a NiCad 18V battery.
Use eddy stock the battery. Li-Ion safety circuits do a lot of great things to keep it in good condition, but they're going to go south if you don't use them. There is no wonder they're stored charged to half-capacity. If you most often use your netbook using AC power while you're at home, make sure that you let it run to the point where windows gives critical battery level warning at least two or three times a week.
These types of batteries also do not receive any damage if you use your phone while its charging. Older cell phones that used older types of batteries would damage the battery if used while charging. This simply is not the case anymore with the newer mobile phone batteries.
Obviously, ICE are powered by the gasoline you buy when you fill up at a gas station. The electric motor/generator is powered by a large (and by large, I mean large and heavy) Lithium battery stocks pack. Most hybrids on the road today have large Nickel-Metal Hydride (NiMH) battery packs somewhere near the trunk, or under the seats. (Read about the Lexus Hybrid battery pack).
The battery will re-charge a little if placed on a hot surface, like a radiator. Never place a mobile phone battery on a hot surface! There is a significant chance of explosion with extreme heat. A modern Lithium mines Ontario battery becomes less efficient the warmer it gets.
My drill of choice that I would say is the best cordless drill is the Makita BDF452H model. For under two hundred dollars, it is a must buy. It features a fifteen minute battery charger and lithium batteries. The drill is extremely lightweight. It is very comfortable in your hand, that it feels like an extension of your arm. It is a very powerful drill and great for any construction project.
So, there you have it; some simple suggestions on how to extend the life of your cell phone battery. Although it's not a going to double or triple the life of your battery, following these guidelines will make it much easier on you and cause less aggravation in the long run.
