Making a rechargeable CR123 is just about impossible, none of the common battery chemistries has the same voltage. When Using more modern battery chemistries, the advantage of CR123 is more the size and voltage, not as much energy or power. The conclusion of the above curves must be that CR123 can easily match two Alkaline AA batteries, when used in a high power flashlight, but needs much less space. The CR123 cannot match the capacity of two AA, when using more modern AA batteries (Lithium and NiMH): How does these batteries compare, when drawing power:Īt 1A the CR123 has higher voltage (most of the time) and more capacity, making it much better for a high power flashlight than a couple of Alkaline AA batteries.īut the CR123 battery does not always win against Alkaline, at lower loads Alkaline AA has more capacity, but cannot match the voltage of CR123. The size of CR123 is about 16.5 mm in diameter and 34 mm in length, the AA is 14 mm in diameter and 50 mm in length and a CR123 weight less than a single AA battery. To get roughly the same voltage, two AA cells are needed. Lets compare performance of this battery to ordinary alkaline AA batteries: Performance comparison to other primary batteries The 1 mm length difference (xx340 to xx350) will seldom be significant. The 18350 battery is not really a replacement for CR123, it has to large a diameter, but when working with flashlights a few are large enough to fit a 18350. 17335 or 17345 can also be used for this size battery. Another name for that size batteries is 16340, first two digits is diameter and last 3 digits is length in 1/10mm (The diameter will often be 0.5mm more than the number specify, the length can be a couple of mm more). Rechargeable batteries that has about the same size is often called RCR123 or R123, this naming is done to signal that they can replace a CR123 (That is not always the case). Often the battery is only called CR123, sometimes only 123 or 123A. The correct name is CR123A and this name might be because it is 2/3 of the A battery size (The A battery is not used anymore). This made small and bright flashlights possible. Surefire did like the battery size and introduced it in flashlights (Around 1988). The CR123 battery was made for use in cameras, where the high current capacity was very useful for the flash and for the motor drive (Back in the film days). This article will be looking at CR123 batteries and some recharge batteries that are supposed to be replacements for CR123 batteries.
