Dewalt Batteries Buying Guide: What is the best battery type for power tools

Dewalt Batteries Buying Guide

A power tool battery is essential in using cordless power tools. These said tools are literally heavy, electrical pieces of equipment. In time, cordless power tools have been more demanded and equally made available. With regards to their batteries, some add bulk and weight while other batteries are lighter. Power tool batteries come in many forms, and there are three major types: NiCd or Nickel- Cadmium, NiMH or Nickel Metal Hydride, and Li-Ion or Lithium-Ion.

What Is the Best Battery Type For Power Tools?

  • NiCD (Nickel-Cadmium)– They are the oldest of the three power tool battery types in this list. They are inexpensive and are known for their durability.
  • NiMH (Nickel Metal-Hydride)– This type is less harmful to the environment as compared to the NiCD. It can last up to three times longer than NiCD batteries.
  • Li-Ion (Lithium-Ion)– It is considered to be the best choice among the list, but it is also pricey.

A power tool is able to perform at its best with a good battery. If one is looking for a rechargeable power tool battery, Dewalt has that to offer. Additionally, Dewalt batteries are available in the forms of NiCD, NiCad, and Li-Ion.

Before heading out to buy your own equipment and battery, make sure you have the knowledge or familiarity with the different factors that affect a battery’s condition.

Some Factors to Consider Before Purchasing Your Power Tool Battery

Effect on Memory – When a battery is repeatedly charged without being fully drained, this causes memory effect. A battery adjusts to the shorter charge range, and that becomes its new charge capacity.
Deep Discharge – This is completely draining the battery with normal tool usage. Some Dewalt batteries periodically require deep discharge to keep it healthy. Unfortunately, other batteries have reduced run times or capacity as an effect.
Run Time – This simply means the amount of time a battery can be used for its capacity. You can tell how well a battery’s capacity is by means of Ah or amperage hours. The higher the Ah, the longer you can use the battery in between charges.
Voltage – The higher the voltage, the more powerful your battery is.
Self-discharge – Batteries discharge on their own when not in use. This happens slowly for some batteries while others lose their energy faster. If you’re tool is subjected to a long storage time, it’s best to make sure that your battery’s self-discharge rate is slow.
