An Extra Power Tool Battery or Two Essential for Maximum Productivity
The days of dragging long power and extension cords around for your tools is a thing of the past, thanks to the extended life of rechargeable batteries these days. When you purchase a tool that mentions it is cordless, chances are you have a power tool battery powering the device. Of course, as with anything that runs off a battery, you eventually have to replace it but for power tools, the battery is typically one that is rechargeable so you get your money's worth out of the tool.
The Typical Rechargeable Battery
When it comes to the power tool battery for your tool, chances are that the primary components inside of it are nickel and cadmium - two elements that help the battery hold the charge. These two elements have proven to be an optimal choice for recharging because the weight of them is less than other options and it is rather efficient during the recharging process.
The nickel-cadmium power tool battery is also a great choice because they present a safe environment for "charging" conditions, have low resistance internally plus there is little voltage variation during the discharge of the battery. The two elements are often used in a variety of other applications which require batteries such as emergency lighting, telephones and even larger toys such as remote controlled airplanes.
Power for Tools
The power tool battery of today can typically last for several continuous hours which is great for home improvement projects around the house. Many cordless tools come with one rechargeable power tool battery but often times you may end up stuck without a tool to use should it become run-down and need recharging. It is best to invest in an extra identical power tool battery for your tool at purchase so that you will always have a spare to rely on.
The typical power tool battery weighs about one pound, give or take a few ounces depending on the type of power tool being used. Cordless drills were the first really big battery-operated tool on the market but it wasn't long before circular saws, jigsaws and more started coming in cordless varieties.
If you are lucky, your extra power tool battery may work for some of your other tools, although this is not likely to occur due to the different size and design of tools. You will find the batteries for these cordless tools come in a variety of different voltages so it is important to choose a tool with a high voltage which translates to more power. In fact, most people will choose a tool because of the power tool battery's voltage rather than its other capabilities because more power is always a good thing.
