If you're going to purchase a cordless tool, then you should really think about getting one with Lithium ion batteries. They cost more, and it's easy to think you could just buy a cheaper model and get a spare battery, but it's not the same. Lithium ion batteries are a true hassle free solution.
There are several types of battery in use at the present time and each must be treated differently. There are Nickel-Cadmium (Ni-Cad), Nickel-Metal Hydride (NiMH) and Lithium-ion. Ni-Cad is old technology and hence only found in ancient handsets, so I will not be covering them in this article. NiMH batteries perform much better than Ni-Cad, typically giving 30% more talk time, but Lithium are thinner and give even higher performance. I will be concentrating on Lithium-ion as it is the most used modern mobile phone battery to date. Check which type of battery your phone has before following any of the following.
True that they contain the same lithium ion stocks amount and they can last the same amount of minutes but sometimes the batteries of one model does not fit the model of another.
Okay, so we know we'd be sunk without our laptops and cell phones. But what about the car? Cars have batteries too. Perhaps you ride a Harley Davidson - not without a motorcycle battery! It's interesting to think where we'd be if the afore-mentioned "zapping episode" took place. We know that our forefathers coped without batteries but could we?
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.
Don't empty the battery completely. Modern safety circuits take care of this, but if you take it to 3% capacity, then leave it like that for three months, it's most probably going to be damaged and lose some of its maximum capacity. If you have to store it for a while, charge it to 60%, and leave it like that in a dry and cold place.
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.
