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?
Speed - you can have variable speed option in these cordless drills. You need to buy a drill which will provide you with the appropriate amount of speed that you want. Depending upon the speed you will be able to screw on things a lot quicker or even slower. So keep the speed in mind while buying it.
If you would rather prefer an entry-level dSLR, then you better get Nikon's D3100. It offers fast performance, superior image quality, and unparalleled control. It features live view, 1080p HD video, and a guide mode that is very user-friendly. It has a three-inch LCD screen, DX-format CMOS sensor, 1080p HD video, and is 14.2 megapixels. It uses a rechargeable cobalt mine ion battery as well as SD, SDHC, and SDXC media cards. Nikon D3100 is one of the lightest and smallest dSLR's available. It is the ideal camera for frequent travelers.
2) Battery freshness: often overlooked. Always make sure you have the freshest battery possible. A battery can lose it's ability to hold a charge as time goes on. You want batteries that move off of shelves quickly to be sure they aren't old.
Another thing to remember is not to store those batteries in the charger as well. This will draw energy away too, and cause your battery to die off sooner than you expect. Keep it away from high heat or extreme coldness. Heat tends to cause damage to your Lithium battery stocks while exposing it to low temperatures over a period of time will draw its charging capacity.
What are you going to be using the drill for? Let's say that you are planning on building some light furniture and maybe will use the drill on weekends mostly. You probably don't need a super powerful drill with the most expensive battery technology. You could probably get by with a 12 volt drill, no need for hammering action, and you could probably do fine with a NiCad battery as opposed to Lithium Ion. Sure, a Lithium mines Ontario Ion battery would be really nice, and would charge faster, but if you aren't planning on using the drill for continuous hours at a time you could save a few bucks in this department.
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.
On the other hand, if you are a camera enthusiast and you want to have the latest digital camera model, then you better wait for the release of Canon PowerShot A3300 IS. Canon's A-series is stylish but it is not as flashy as the others. Nevertheless, it never fails to deliver solid image quality, optical image stabilization, and a good feature set. It is also very affordable, truly perfect for camera enthusiasts and frequent travelers. Some of its specifications include 6 megapixels, 5x optical zoom, CCD sensor, 720p HD video, 3-inch LCD screen, and 28mm wide-angle lens. It captures to SD/SDHC memory cards and uses a lithium ion battery.
