Description
This is a single LR1 alkaline cell from Energizer, supplied one to a blister pack. The retail pack gives it as a 1.5V alkaline battery and prints both of the codes it answers to, LR1 and E90, on the front. LR1 is the international code for this cell size and E90 is Energizer's own reference for exactly the same battery. Alkaline chemistry is the everyday choice at this size: it holds a nominal 1.5V, it is a primary cell rather than a rechargeable one, and it stores well between uses.
The LR1 is a specialist size rather than a supermarket staple, so the useful thing to do before ordering is to read the cell you are taking out. If the old one is marked LR1, E90 or N, this is the replacement for it. If it carries a different code, a battery of broadly similar appearance is not necessarily the same fit, so match the code rather than the look, and check the manual if the old cell is unreadable. Because this size is harder to pick up locally than an AA, people who own something that takes one usually keep a spare or two to hand.
One cell comes per pack, and the listing is sold in multiples of ten with ten as the smallest order, which suits a workshop, a maintenance store or a service van rather than a one off purchase. Energizer prints no shelf life figure on this card. It sits alongside the other Energizer cells we stock, from AA and AAA through C, D and 9V to lithium and silver oxide coin cells, if you are restocking a battery drawer in one go.

Frequently Asked
What is the difference between LR1 and E90?
Nothing in practice. LR1 is the international code for this cell size and E90 is Energizer's own reference for it, and both are printed on the front of the pack.
Is this the same as an N size battery?
Yes. This 1.5V cell is listed as LR1, E90 or N depending on whose catalogue you are reading, so any of those three codes leads to this battery.
How many batteries do I actually receive?
One cell per pack. The minimum order here is ten packs, sold in multiples of ten, so the smallest quantity you can buy is ten cells.
Can these be recharged?
No. Alkaline cells are primary batteries, meant to be used once and then recycled, so only cells sold as rechargeable should ever go into a charger.
What voltage does it give?
A nominal 1.5V, as printed on the pack. If your device calls for 1.5V in this size, an alkaline LR1 is the standard fit for it.
