Description
This is a pack of two Energizer Max Plus D cells, the largest of the common cylindrical battery sizes. Each one is a 1.5V alkaline primary cell, a single-use chemistry that is not meant to be recharged. The retail pack prints a 10 year shelf life, which is the figure Energizer puts on the card rather than a run time in any particular device. Alkaline is the workhorse chemistry for household cells: steady voltage, wide temperature tolerance and no special handling.
D cells are the format the bigger battery-powered things take: rubber torches and work lamps, camping and storm lanterns, portable radios, doorbell chime units and some ride-on toys. A D cell is physically much larger than an AA of the same chemistry, so it holds considerably more energy and can supply the steadier current a motor, a filament bulb or a speaker wants over hours rather than minutes. Two cells is the common requirement for a full-size torch, so one pack fills a light. Before ordering, open the battery compartment and check both the number of cells and the moulded diagram showing which way round they sit.
Alkaline cells lose very little charge sitting in a drawer, which is what the 10 year figure on the pack is about, so keeping a spare pack with the torch is worthwhile. These are single-use cells and must not be put into a charger. Each unit you order is one blister card holding two D cells, and the listing carries a minimum order of six, sold in multiples of six, which suits a shop counter, a maintenance cupboard or a household that would rather buy once. We stock Energizer cells across the common sizes, including AA, AAA, C, D and 9V, as well as lithium and coin cells such as CR123 and CR2032.

Frequently Asked
What sort of devices take D size batteries?
Large torches and work lamps, camping and storm lanterns, portable radios, doorbell chime units and some ride-on toys. Check the compartment marking before you buy.
How many cells do I get in one pack?
Two D cells on a single blister card. The minimum order on this listing is six packs, so twelve cells in total, in multiples of six packs.
Can these be recharged?
No. These are alkaline primary cells, designed for single use, and they must never be put into a charger. Choose a rechargeable NiMH cell if you want to recharge.
Is a D cell interchangeable with a C cell?
No. A D cell is both longer and fatter than a C cell, so it will not sit in a C compartment and a C will rattle loose in a D one.
What does the code LR20 mean?
LR20 is the international designation for a 1.5V alkaline cell in the D size, so a device asking for LR20 is asking for exactly this cell.
How long will an unused pack keep?
The pack prints a 10 year shelf life. Store the cells somewhere dry at ordinary room temperature and leave them on the card until you need them.
