Because the battery is what allows cordless tools to function, the sort of battery technology used is almost as crucial as the tool itself. If the battery’s capacity, charging time, or storage properties aren’t right for the job or the user, the pricey tool it’s linked to may not be very useful.

Cordless power tools are everywhere, and they’re just getting more popular. Every year, manufacturers introduce more cordless variants, as well as more powerful ones. Furthermore, battery power tools for sale technology is undergoing tremendous evolution. This means that there are more battery alternatives available (and that we’ll likely see more), and that many of those batteries will be able to perform more work than ever before.

To stay up with the industry, customers should be as knowledgeable as possible about battery designs, performance, specs, and features. This article provides cordless tool users and purchasers the knowledge they need to identify the proper rechargeable battery types for their cordless tools and then get the most out of them.

Characteristics of Rechargeable Batteries

Before buying a cordless power tool, customers should familiarise themselves with a few words and features related to rechargeable batteries. Things that affect a battery’s total life and run time are generally the deciding considerations when power tool battery purchasers make a selection (apart from price, of course), therefore most of the qualities listed below have some bearing on how long a battery will last.

Life of a cycle

The number of charge cycles a battery can sustain before totally losing its charge capacity or ability to transmit energy is the battery’s overall life. NiCd batteries, for example, often have a cycle life of 1,000 charges (cycles) or more. All rechargeable batteries will ultimately wear out, but for various reasons.


The voltage of a battery dictates how much power it can produce at any one time. Simply put, higher-voltage cordless instruments are more powerful. Individual cells make up the majority of rechargeable power tool batteries. The total voltage of the battery is determined by the combined voltage of the cells; however, individual battery cell voltage capacity varies by type of battery (NiCD, NiMH, Li-Ion).


This is the amount of time a battery can run without needing to be recharged. The quantity of ampere hours (Ah) that a battery can deliver is commonly represented as its capacity. The tool’s total amperage rating differs from “Ah” (the current at which the tool operates). Instead, Ah refers to the amount of energy the battery can store, not the amount of current it can handle when in use.

A large discharge

Allowing a tool battery to entirely discharge its energy during regular use is known as deep discharge. Deep discharge can be a concern for some batteries, reducing their cycle life and capacity significantly. Deep discharge is not an issue with other battery types. In addition, to maintain the battery healthy, certain batteries require severe drain on a regular basis. Users who do not use their cordless equipment frequently may find this additional maintenance to be inconvenient.


Many jobs are made easier with the use of cordless tools. However, not everything has to be cordless. Don’t be hesitant to purchase corded or pneumatic mitre saws, table saws, high-power grinders, and other tools. While experienced craftsmen typically profit greatly from cutting the cord, most DIYers and infrequent users would be better served by investing in a more polished corded version. If you’re still not convinced, professional job sites around the country have a plethora of corded and pneumatic power tools.
