With all the staying at home that’s going on, there is a lot of DIY to go with it. Whether it’s overdue repairs, new projects, or something creative like betting up a mini golf course for the kids, power tools are getting a workout.

Power tools, of course, work under battery power, and batteries in this sort of equipment have the tendency to go flat long before you’ve finished using them. While they’re rechargeable, none of us like to wait and there’s a big chance you’ll run out of time or motivation while waiting for the recharge.

Why not invest in a second battery? Use the first, then transfer to the second battery while the first is recharging. There’s no down-time and your work is finished faster and more efficiently.

Choosing the correct battery for the tool is essential. With a variety of technologies, sizes, and prices to influence your choice, it can be hard to make the right selection. If the battery is not right for the tool, you won’t get much out of the tool.

Different technologies for power tool batteries include nickel cadmium (Ni/Cd), nickel metal hydride (NiMH) and lithium ion (Li-Ion).

NiCd batteries utilise the oldest of the technologies and are still in use because they’re cheap, nearly indestructible, and have a long cycle life – they don’t go flat quickly. They are heavy, though, making it hard to use the tool over a long period, are less powerful than the other technologies and more damaging to the environment.

NiMH batteries have better capacity than NiCd and are less environmentally harmful, however they are temperature sensitive and don’t like deep discharge. You need to recharge before they go flat.

Li-Ion batteries are the newest technology. They outperform the other types and they are more tolerant of charging issues, however the price can be a barrier, and they are very heat sensitive.

The size of the battery is as important as whether the power tool was designed to accommodate the battery technology you choose. It’s pretty simple: the wrong size just won’t fit.

If you know exactly what you need, go ahead and buy it. If you’re unsure, it’s best to talk to the experts and it can be good practice to take the power tool to the store with you to ensure you get the right battery for your needs.
