Energizer 2CR5 Lithium Battery

The 2CR5 is a six volt lithium battery, and this listing is for a single cell in its retail pack. It is a fixed format rather than a general purpose size: one moulded body in black and silver that seats in a device one way round, so there is nothing to wire and no adapter to buy. The chemistry is lithium and the rating is 6V, both printed on the pack. Our supplier files the code as 2CR5M while the pack itself prints 2CR5, and we have followed the pack.

Equipment that needs a 2CR5 says so on the battery door or in the handbook, and the code is the thing to match rather than the shape or the brand. It is the format specified by a good many 35mm autofocus film cameras, and it also turns up in sensors, meters and access units that need six volts from one compact block instead of four separate cells. If you are buying for a camera that only comes out occasionally, a spare in the bag is worth having, because a flat cell in a device with no other power source stops the job dead.

Lithium holds its charge in storage far better than everyday alkaline chemistry, which is why the pack states a ten year shelf life. Keep the cell in its blister until you need it. One cell arrives per pack, and this line carries a minimum order of six, sold in multiples of six, so it suits a camera club, a maintenance store or anyone keeping a small stock of specialist sizes. It sits alongside our other Energizer cells, from AA and AAA to C, D, 9V and the lithium coin sizes.

How do I know my device takes a 2CR5?

Open the battery compartment and read the moulding or the label inside it, or check the handbook. The code is what matters, and a 2CR5 will not physically fit a holder made for anything else.

Is 2CR5M the same thing as 2CR5?

Our supplier records this line as 2CR5M and the retail pack prints 2CR5. Match the 2CR5 code marked on your equipment, and if the handbook shows a different code entirely, ask us before ordering.

How many cells do I actually receive?

One cell per pack. The minimum order on this line is six packs, sold in multiples of six, so the smallest purchase is six individual cells.

What voltage does it give, and can I use two three volt cells instead?

The pack is rated 6V from a single body. Two separate three volt cells are not a substitute, because the holder is moulded for the 2CR5 shape and its contact positions.

Can it be recharged?

No. The chemistry given is lithium, a single use primary chemistry, so there is no charging to do. Take spent cells to a battery recycling point rather than putting them in household waste.

How long will it keep before I use it?

The pack states a ten year shelf life. Store it in the unopened blister at normal room temperature and away from loose metal such as keys or coins.
