Duracell Plus Power D Batteries (LR20) - 4 Pack

These are D cells, the largest of the common cylindrical battery sizes, supplied four to a pack. The chemistry is alkaline and the nominal voltage is 1.5V per cell, which is the standard for this size and the figure you will see marked inside the battery compartment of most devices that take them. The codes to match are LR20 and MN1300, both printed on the retail pack: if either appears on the old cell you are replacing or in an appliance manual, a D cell is what you need.

D cells suit jobs that need a long run rather than a brief one. Large rubber torches and work lanterns take them, as do portable radios, wireless door chimes, camping lights, some ride-on toys and the bigger battery-driven wall clocks. The size is easy to confirm by eye: a D cell is the fat one, noticeably wider and taller than the AA cells in a television remote, and a device built for them usually has a deep barrel or a wide tray with a sprung contact at one end. Where a torch takes two, a pack of four leaves you a spare set on the shelf.

Four cells in the pack means a matched set, and it is worth fitting them together rather than putting one fresh cell beside three tired ones, because in a series string the weakest cell sets the pace for all of them. This listing carries a minimum order of six, sold in multiples of six, so the smallest order brings twenty-four cells: sensible for a workshop, a village hall or anyone who keeps a stock drawer. Loose cells are best left in the pack until they are wanted, since the terminals can bridge against keys or coins. Alongside these we stock Duracell lithium coin cells, silver oxide watch cells and LR44 alkaline cells.

What is the difference between a D cell and an LR20?

There is none. LR20 is the international code for an alkaline D cell and MN1300 is Duracell's own reference for the same size, so all three names describe what is in this pack.

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

Each pack holds four D cells. The minimum order on this listing is six packs, sold in multiples of six, which works out at twenty-four cells in the smallest order.

Can these be recharged?

No. Alkaline cells are single use by chemistry and should never be put on a charger. Rechargeable D cells are a separate product with a different chemistry and a lower cell voltage.

Will a D cell work in a device that asks for C cells?

No. A C cell is both shorter and narrower, so a D will not go into a C compartment and a C will not hold contact in a D one.

Does the manufacturer state a storage life for this pack?

No shelf life figure is stated for this pack, so none is quoted here. Keep spares somewhere dry at ordinary room temperature and fit the oldest cells first.
