Energizer Max D Batteries (LR20) - 4 Pack

This is a pack of four Energizer Max D cells, the largest of the common cylindrical battery sizes and the one that larger torches, camping lanterns and older portable radios are built around. Each cell is alkaline and gives 1.5 volts, the same nominal voltage as an AA or a AAA. The difference is not voltage but capacity: a D cell holds a great deal more of it, which is why equipment that draws hard or runs for long stretches uses this size rather than something smaller. Alkaline D cells carry the IEC code LR20, so if the old cell in the drawer is marked LR20, this is the right replacement.

D cells are the size people reach for when something has to keep going without attention. Think of the heavy rubber torch kept in the car or the shed, a camping lantern, a garden or workshop radio, a bilge pump, a large wall clock in a hall, or the battery compartment under a child's ride-on toy. They also turn up in emergency kit, where the point is less about how bright the light is on the first night and more about whether it still works on the fourth. Because a D cell is physically big, it is easy to check compatibility before you buy: nothing else in the drawer looks like one, and a device that takes C cells will not accept them.

The retail pack prints a 10 year shelf life, which matters more on a D cell than on most sizes, since these often sit unused in a torch waiting for a power cut. One pack contains four cells, and this listing has a minimum order of six packs, sold in multiples of six. We stock Energizer cells across the common sizes, including AA, AAA, C, D, 9V and lithium coin cells, so a single order can cover the whole house.

Is a D cell the same thing as an LR20?

Yes. LR20 is the IEC code for an alkaline D size cell, so a device or manual marked LR20 takes exactly these.

How many cells do I get, and how many packs do I have to order?

Each pack holds four D cells. The listing carries a minimum order of six packs, sold in multiples of six.

Can these be recharged?

No. These are single use alkaline cells. Rechargeable D cells use a different chemistry and have to be bought as rechargeables from the outset.

What does the 10 year shelf life on the pack mean?

The pack states a 10 year shelf life, so unused cells kept in ordinary dry storage should still hold their charge when you come to fit them.

Will these fit something designed for C cells?

No. A D cell is both wider and longer than a C cell, so it will not sit in a C compartment.

Is a capacity figure in milliamp hours given for this line?

No capacity figure is stated by the manufacturer, so we do not quote one. What is confirmed is a standard 1.5 volt alkaline D cell.
