Description
This is the Energizer LR44 alkaline button cell, supplied two to a blister. LR44 and A76 are two names for the same cell, so if the spent one in your device is marked one way while the manual quotes the other, this is still the right part. The pack gives them as 1.5V alkaline, the same nominal voltage as an AA or an AAA, in a coin format. Alkaline is the workhorse chemistry for this size: steady output, sensible cost per cell and nothing special to think about in use.
The LR44 sits inside a lot of small everyday kit: laser pointers, kitchen scales, digital thermometers, calculators, tyre gauges, keyring torches, glucose meters and a great many children's toys and novelty lights. Devices built around it often take three or four stacked in a column, which is worth knowing before you order a single blister. The safest check is to take the old cell out and read the code stamped on its face. If it reads LR44 or A76, this is a direct swap. If it begins SR, the device was built around a silver oxide cell, which is a different chemistry and holds its voltage in a different way.
One unit of this listing is a single blister of two cells, and the minimum order is ten units, so twenty cells in all. That suits a workshop drawer, a school science store or anyone keeping spares for small gadgets. Keep them in their packaging somewhere dry and at ordinary room temperature, and keep used cells apart from fresh ones. Button cells are dangerous if swallowed, so store them out of reach of children and pets, and take spent ones to a battery recycling point rather than the bin. This listing sits alongside our wider Energizer range, which runs from AA and AAA alkaline through C, D and 9V to lithium coin cells.

Frequently Asked
Is an LR44 the same cell as an A76?
Yes. LR44 and A76 are two codes for the same 1.5V alkaline button cell, so either marking on your old battery points here.
How many cells do I actually receive?
One unit is a blister holding two cells, and the minimum order is ten units, so a first order brings twenty cells.
What voltage do these give?
The pack states 1.5V alkaline, the same nominal voltage as a AA or AAA cell, delivered here in a coin sized body.
My device stacks three or four of these. Should I change them all at once?
Yes, replace the whole stack together. Mixing a fresh cell with partly used ones leaves the weakest cell limiting the whole column.
How do I tell an LR44 from a silver oxide SR44?
Read the code on the old cell. Codes beginning LR are alkaline and codes beginning SR are silver oxide, and the two behave differently.
Is a shelf life printed on the pack?
The manufacturer does not quote a shelf life figure for this cell.
