You might ask "What is the 3V motherboard battery"? On the majority of PCs the motherboard holds a +3 Volt Lithium Battery which is used for two functions. Firstly it keeps the computer time updated. Secondly, on older PC's it keeps the BIOS settings (Low level start-up instructions) in memory.
This classy device will set you back as much as $179, which is a bit steep considering that you can buy a Bluetooth headset now for as little as $30, but you get what you pay for.
Using your mobile phone lithium stock in G or Dual Mode drains the battery much quicker than just GSM mode. Somewhere in the manual for your phone will be listed the battery times separately for GSM and 3G. On modern mobile phones, the GSM only life-cycle can be up to 50% more efficient.
Li-ion Batteries last longer and charge quickly. A Li-ion battery and a quick charger make it possible to work all day with a cordless drill without stopping.
When you store it, make sure the temperature is not too high nor too low. Don't freeze it and storing the unit in a hot car or near the radiator is a bad idea as well. Use a sealable bag, charge the Lithium battery stocks to about 50% and put it into the fridge between 0 and 5C.
What are your driving habits? What are the longest distances you will be traveling? When driving a pure electric vehicle; if the battery runs out completely with no charging stations available you will be stranded. With the long charge times, it will take some time to make the vehicle usable again. This is where the extended range Lithium mines Ontario Volt becomes more practical. Filling up the gas tank is faster than waiting for the battery to charge.
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.
