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.
With its integrated L.E.D. light, you never have to be troubled about operating in dark locations. This relieves the anxiety of constantly having to carry a flashlight with you.
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 mines ontario 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.
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.
If your cordless tools were acquired a long time ago, the battery and charger were of an older technology. The new generation batteries are more efficient and can be charged very quickly. That can be a slight problem with the older charger. The newer chargers have a smart sensing circuit that will cut down Lithium mines Ontario the charge rate as the battery is close to getting full. But for older chargers that do not have such smart circuits, they can overcharge the battery, making it hot when it's left on the charger for extended amount of time. So it's worth the time to investigate if a newer type of charger should be in order when getting a new replacement battery.
Some cordless impact drills are now using lithium-ion batteries which take a lot less time to get a full charge. For instance, I personally use a Makita 18V lithium-ion impact drill and it takes fifteen minutes to charge as opposed to my standard 18V Dewalt drill. The Makita is also equipped with a built-in LED light for illuminating areas with little to no light. The LED light feature in particular is one of my favorites.
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.
