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.
The battery chemistry has 3 types: NiCad, NiMH, and Lithium-ion. NiCad, or NiCd, battery is used in older cordless drill tools. They are the least expensive, so almost all inexpensive cordless tools use this type of battery. There is one problem with this battery. It's toxic to the environment. So when it's time to dispose the dead NiCd battery it's a problem.
Why lithium stocks copyright-ion battery? Because it provides high energy density, runtime, and is light in weight. To run a power-sucking laptop, a battery with high energy density is required. The runtime of a laptop battery is based on what sort of applications you run. If you run basic applications for writing, reading, copying, chatting, etc, then your laptop battery runtime will be high compared to running a complex application that has a huge number crunching requirement.
I spent a few days looking over the internet for a decent camera that would fit an amateur photographer like myself. I decided to go with the Canon EOS 1000D.
Additional features include a built-in L.E.D. light on the drill which will help illuminate the working area when sufficient light is not available. Plus, a phosphorescent bumper ring which glows in the dark will allow the driver to be found even in the darkest environment without additional lighting. Lastly, the driver comes as a kit with two compact Lithium battery stocks-Ion batteries, a 15 minute rapid charger and a convenient tool case for carrying the tool and accessories.
ONickel Metal Hydride (NiMh) - Popular battery about 1-2 years ago. They are lighter than Nickel Cadmium batteries, but heavier than Lithium mines Ontario batteries. These should be cycled once in a while for optimum performance.
If your drill didn't come with a second battery (my cordless Bosch drill did) than you will either have to purchase a second battery or take a short break until your battery is ready.
Of course, there will be Apps. Smart phones right now are all about the apps. You need to do a bit of search. This is necessary since the right apps will help you and nasty ones will just be a liability and will eat up your space. There are also paid and free apps so if you really want to make the most out of your smart phone use, check out the options and invest on good ones.
