Energizer CR123 Photo Lithium Batteries - 2 Pack

A CR123 is a squat cylindrical cell rather than a coin or a standard round cell, and lithium is the normal chemistry for the size rather than an upgrade on it. These Energizer cells are lithium, and the pack's small print gives 3V, twice the nominal voltage of a single alkaline cell, which is why kit designed around CR123 usually takes one or two of them where an alkaline device would want four. Two cells come in the blister, and the front of the pack prints a 10 year shelf life.

This is the size that compact high output torches, film and older digital cameras, laser sights and a great many wireless alarm parts are built around: motion sensors, door and window contacts and doorbell push units. If you look after a house alarm or a camera that has sat in a drawer for a few years, two at a time is usually right, because most of those devices take a single cell and a spare on the shelf saves a trip. Check the marking on the old cell first: CR123, CR123A and plain 123 name this size, while CR2 and CR-P2 are different cells that will not fit.

Lithium primary cells hold their charge in storage far better than most chemistries, which is what the pack's 10 year figure speaks to; they are single use, so they are not charged again once flat. We sell these two cells to a pack, with a minimum order of six, sold in multiples of six, so the smallest order brings twelve cells in all, which suits a whole alarm system or a box kept in the store cupboard. They sit alongside our wider range of Energizer batteries, which includes AA, AAA, C, D and 9V alkalines as well as lithium coin cells.

What sort of devices take a CR123 cell?

Compact torches, film and older digital cameras, laser sights and wireless alarm parts such as motion sensors and door contacts are the usual homes for this size.

How many cells do I get, and what is the minimum order?

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

Are these rechargeable?

No. CR123 is a primary lithium size, made to be used once and then replaced; rechargeable RCR123 cells are a separate product at a different voltage.

How long can I keep spares before using them?

The retail pack states a 10 year shelf life, so a spare bought today should still be serviceable long after the cell currently in the device has gone flat.

Will a cell marked 123A or CR2 fit the same holder?

A cell marked CR123A or plain 123 is the same size and fits. CR2 and CR-P2 are different cells and will not sit in a CR123 holder.

What voltage does each cell give?

The pack states 3V per cell, double a standard alkaline round cell, so a device built around one CR123 should not be given alkalines instead.
