What should I look for when buying Batteries?

The ToolStore UK range of Batteries includes Lithium-Ion batteries for use with cordless power tools and AA and AAA batteries for handheld devices. Whatever batteries you need, ToolStore UK is here to help.

If you’re choosing a battery for your power tool, there are two major things to check: that you have the correct voltage and that it provides the amount of power, measured in ampere hours (ah) that you need.

The voltage is the most important aspect as most cordless tools will only run at their stated voltage. There are some exceptions, such as the DeWalt FlexVolt range which can run in both 18v and 54v modes.

If you’re going to be using the tool over a long period, the weight of the battery is also worth checking; this can have an impact on your comfort.

In terms of power for handheld devices, ToolStore UK offers AA, AAA, C, D and 9.6v batteries in a range of pack sizes.
