The first rule you need to be familiar with when choosing a cordless drill is this simple fact-the battery you choose to power this tool will ultimately determine the strength and torque you will get. Obviously, the higher the voltage of the battery, the more power you can expect to get from your cordless drill. While this seems to be very exciting option, there are tradeoffs to be made with a higher voltage cordless tool. There is the burden of additional cost and additional weight if you are going for a higher voltage solution for your drilling needs.
People like to buy cheap computers, it's somehow coded into our DNA. The problem with this practice is that often netbooks are cleared from stock after a few months of unsuccessful attempts at selling it for a higher price. These notebooks come with battery stored in the right circumstances but for too long.
Use lithium battery stocks 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.
When it's time to buy a new lithium ion battery, be sure you're buying one that's new (as in recently produced). Just like fruit has a shelf-life, so do batteries and just like you want to buy fresh produce, you also want to invest in "fresh" lithium ion cells. Check the date-code on the battery or packaging to ensure you're not buying a pack that's been degrading for a year on some shelf.

Some experts talk about running water being safer than still water, but studies have found lake water to be among the cleanest because the ultraviolet rays of the sun kill bacteria near the surface. When taking water from a lake or pond, take water under the surface, but near the surface. Check the rate of water that is flowing into and out of the lake. Are there any stock animals or other animals that could make the water impure?
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.
