Replacement Power Tool Battery

power tool batteryWhen choosing the correct replacement power tool battery, you have to know what you are going to use these batteries for. Batteries for cordless tools are usually used to help most workers in performing at their best in a short time. But with so many power tool batteries in the market, you are brought into a confusion on what to buy. You have to know the three basic specifications the usually affects the performance of any rechargeable batteries. They are:

- The material type used in the battery
- The voltage of the battery
- The capacity of the battery (which is usually measured in amp hours)

By knowing these specifications, you are now given with choices on the types of batteries that you have to look at. It is important for you to consider the life expectancy, recharge time, costs and environmental tolerance of a battery before buying them.

Cordless tool batteries are usually made using three materials:

NiCd (Nickel Cadmium) batteries

These are usually the oldest among the types of materials used for cordless tool batteries. It is used for industrial purposes since the 50s. It is also the most economical among all the batteries in the market. They are commonly available in AA sizes, making them convenient to replace the standard AA batteries being sold in many hardware stores. NiCd batteries are also popular for its long life, which can last up to 1500 charge cycles.

NiMH (Nickel-Metal Hydride) batteries

Its main advantage over the NiCd is its energy density that is around 50 percent higher than a standard NiCd. This just means that when you are using this type of battery, you can drill 50 percent more holes or even cut 50 percent more materials before recharging it. The down side is that NiMH can’t handle recharging so well. It only last for about 1/3 to 1/5 of the number of cycles for NiCd batteries.

Li-ion (Lithium Ion) batteries

This is the newest type of these batteries that you can see in the market today. The good thing about li-ion batteries is that it has a double energy density to that of NiCd batteries. This allows the user to have a complete double work when you are recharging. Special circuitries are built in battery chargers, especially designed for these newer li-ion tool batteries.

You can recharge your batteries up to 80 percent in as fast as 30 minutes. For an average power tool job, a worker using the tool with a li-ion battery will never have to use a second battery as replacement. Another good thing about these batteries is that they are lighter to carry. One down side for this kind of power tool battery is that it doesn’t have long life like the NiCd batteries—lasting up to 1,000 cycles of charging.

Choosing the perfect tool battery will help your tools last longer and perform better, so choose wisely.
