What D batteries power

D size LR20 cells power the higher-drain kit around the home, such as torches, radios, lanterns and other gear that runs for long stretches or draws plenty of current. Their larger body holds more capacity than smaller cells, which is why they suit devices that need to keep going.

Battery types

The range covers alkaline, rechargeable NiMH and zinc carbon types, so you can match the cell to the job. Alkaline suits most everyday devices and offers a sensible balance of life and cost. Zinc carbon is a budget option for low-drain items, while rechargeable NiMH cells can be topped up and reused for kit you run often.

Voltage and what it means

The cell types here do not all run at the same voltage. Most devices designed for D cells take either in their stride, though it is worth checking the device if it is sensitive to voltage. The LR20 marking confirms you have the right alkaline size when you compare against your old cell.

Pack sizes

Pack sizes run from singles up to bulk boxes, so a household can buy a pair for a torch while a site getting through plenty can stock up in one go. Keeping a few spares in a drawer means a flat torch is a quick fix rather than a trip out.

How to choose

Pick alkaline for everyday torches and radios, zinc carbon for low-drain or occasional items, and rechargeable NiMH where you get through cells quickly. Then match the pack size to how often you swap them. Free UK delivery over £99, worldwide shipping.
