When you do something processor intensive, plug in the charger.

Why is this important? If you have a relatively new PC the only problem you will get are error messages relating to the clock on start up. No big deal. If your PC is older then a low battery could be a nightmare. I had a PC which once lithium ion stocks every few months refused to boot. Rather than take the PC in for repair or start replacing parts myself the first thing I did was look at the BIOS settings. It was soon obvious that the BIOS settings were corrupt (wrong bus speed). I put a volt meter on the battery and sure enough it was reading 2.2 volts.
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.

The suggested hull design is a deep-V as it provides stability in rough waters and makes it easy for the boat to cut through any direction for superior maneuverability.
Most automakers would like to see Lithium-Ion battery packs (you probably have a Li-Ion battery in your cell phone) which can store more energy. But as of right now, they are still too volatile/unreliable when placed in large packs for major carmakers to use. But that should be changing in the next few years. Both GM (with their Plug-In Saturn Vue) and Toyota (next generation Prius/ Hybrid Systems) believe the next generation of hybrids will come with Li-Ion battery packs.
Another one of the best drills out there is the Panasonic EY7540LN2L model. It makes fastening jobs a cinch. It is lightweight, and ergonomic. It is extremely easy on the wrist and hands, so it is comfortable to use. It has long lasting lithium batteries for longer jobs. It is an impact driver, and is definitely versatile. It costs more than the other two drills, but it is still one of the best. Overall, any of the drills mentioned above would be a great cordless drill to own.
