TOOLBOX TALKS – CORDLESS TECHNOLOGY

It's more than a revolution, it's a way of life

Cordless technology is constantly evolving and it’s now more than a revolution, it’s a way of life.

We’ve examined the evolution of batteries, so now we think it’s essential to de-mystify the voltage and amp hours, which means you can select the right batteries to fit to your tool park.

Why not follow suit of these customers and their cordless tool parks. . .

De-mystifying voltage and amp hours

Nowadays, the cordless market offers a wide range of tools from screw drivers, saws, grinders, combi hammers, vacuum cleaners and much more. To match the varying demands of different tools, they are offered on a variety of battery platforms which is defined by the voltage, for example 12V, 22V and 36V, and the amp-hour (Ah) hour capacity, for example, 2.6Ah, 5.2Ah or 8.0Ah.

But what do all these numbers mean and how can you tell what’s the capability of a battery actually is?

How much energy is stored in the battery is a measure for the amount of work that can be performed with one battery charge. This energy content is expressed in Watt-hours (Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by the amount of charge (Ah) the battery can hold. If a battery holds 5.2Ah it can deliver 5.2 Amps for 1 hour or e.g. 4*5.2=20.8 Amps for ¼ hour = 15 minutes.
