Comparison

CRP2 vs CR2 vs 2CR5

CRP2 (IEC CR-P2) is a 6V lithium photo pack. CR2 is a single 3V lithium cylinder. 2CR5 is a different 6V dual-cell pack. Same “photo lithium” shopping aisle is not the same battery.

CRP2 / CR-P2

6V lithium photographic pack (also DL223A / EL223AP / PC223 on many packs). Nikon N6000 and AF3 on this site each take one CRP2 / DL223A. Match the empty pack outline — not a single CR2 cylinder.

CR2

Single 3V lithium cylinder (shorter than CR123A). Common in later compact and some SLR/APS bodies. Not a CRP2 pack and not 2CR5.

2CR5

6V dual-cell lithium pack used in many mid-era Canon Sure Shot / Prima bodies. Different outline from CRP2 — match the empty pack or device page.

Quick rule

Read the full code on the empty pack. CRP2 ≠ CR2 ≠ 2CR5 ≠ CR123A. Open the battery or device page before buying.
