6 V · 6 V lithium manganese dioxide pack
2CR5 is a 6 V lithium/manganese dioxide camera pack. Energizer's sheet (EL2CR5) prints ANSI-5032LC, IEC-2CR5, 1500 mAh to 2.0 V on 200 Ω at 21°C. The can is prismatic. The cross-reference guide also lists the labels 245, RL2CR5, 2CR5M and KL2CR5.

Can I substitute it?
Not a pair of CR123A cells you tape together, and not a CR-P2. The packs are different shapes. Match 2CR5.
Size check at real size
Lay the old cell on the outline. This shows the top outline and the front outline at 1:1 once the screen is calibrated.
2CR5 outline, envelope maximums. Not a photograph, drawn from the figures above.
Calibrate this screen
Screens scale pages differently, so true size is only true after calibration. Hold a bank card or ID card (85.60 mm wide, ISO/IEC 7810 ID-1) against the bar and slide until the bar is exactly as wide as the card.

Small lithium cylinders and camera packs
CR123A, CR2, CR-P2 and 2CR5 are lithium/manganese dioxide, the same chemistry as a CR coin, in a different can. Energizer 123 is the CR123A type: the sheet prints IEC-CR17345, ANSI-5018LC, nominal 3.0 V, and 1500 mAh to 2.0 V on 100 Ω at 21°C. The drawing's maximums include 17.00 mm and 34.50 mm. It is a single 3 V cell. It is not an AA, and it is not the 12 V A23, which is a stack of alkaline button cells in a thinner tube.
CR-P2 (Energizer 223) and 2CR5 are 6 V packs used in cameras and some fobs. Each Energizer sheet rates 1500 mAh. The cutoff on the CR-P2 sheet is 4.0 V; on the 2CR5 sheet it is 2.0 V. Same milliamp-hour headline, different test. The cans are prismatic. A diameter-and-height search does not apply, and the pages say so.
CR2 is on Energizer's replacement guide (cell size 1CR2, labels CR2, RLCR2, KCR2, photo and connected-home devices). A product datasheet for it was not available at the URLs we tried, so voltage, capacity and millimetres are left blank rather than filled in from memory.
