Energizer Alkaline 4LR44 Batteries (A544) - 2 Pack

The 4LR44 is a 6V alkaline battery, and it looks like a short, fat cylinder rather than the coin cell people often picture when they read the code. The code itself tells you why: four alkaline round cells of 1.5V each, stacked in series inside one sealed case. That is the whole point of the format, because a device that needs 6V out of a very small space gets it from a single battery instead of four loose ones in a holder. The retail pack prints both of the names this cell answers to, 4LR44 and A544, and they are the same battery.

Two cells come in each pack. The 4LR44 is the size usually called for in dog training and bark control collars, in small medical devices such as blood glucose meters, in laser pointers and pens, and in some older film cameras and hand held light meters. Before ordering, take the flat cell out and read the printing along its side, or check the battery figures in the device manual. Either 4LR44 or A544 printed there means this is the right cell. Something of the same physical size but a different voltage is not a substitute, so 6V is the figure to match.

Alkaline is a primary chemistry, so these are used once and replaced rather than put on a charger. One pack holds two cells and the minimum order on this listing is six packs, sold in multiples of six, which brings twelve cells in total and suits a household running more than one collar or meter, or a workshop that likes spares to hand. We stock plenty else from Energizer alongside it: alkaline LR44 and A23 cells, alkaline power AA, AAA, C, D and 9V, and lithium coin cells including the CR2032 and the CR123.

Is the A544 the same battery as the 4LR44?

Yes. They are two codes for the same 6V alkaline cell, and the retail pack prints both, because device manuals are inconsistent about which name they quote.

How many batteries do I actually receive?

Each pack holds two cells. The minimum order is six packs, sold in multiples of six, so a first order brings you twelve cells in total.

Can I fit a 1.5V cell of similar size instead?

No. This battery gives 6V from four alkaline cells sealed in one case, and a single 1.5V cell will not run equipment designed around that voltage.

Are these rechargeable?

No. Alkaline is a single use chemistry, so the cells are replaced once flat rather than charged. A charger will not restore them.

How long will they keep before I use them?

Energizer does not print a shelf life figure for this cell.
