People also ask, is there a difference between cr123a and 123 batteries?
Re: Difference between 123 and 123a Batteries 123, 123A, CR123, CR123A, SF123 are all the same thing - a 3V ~1500 mAh cylindrical lithium cell ~0.650" dia x 1.350" L. They have a positive button top. The button should have 2 or 3 small vents in it to prevent "exposive disassembly" failure mode.
Beside above, why are cr123 batteries so expensive? The reason these 123's are so expensive is because people will pay that money for them. This is the only reason. They should cost under a dollar apiece. Your solution is to buy some rechargeable 123's and a charger and away you go.
In this way, are all cr123a batteries the same?
OP as per your question the answer is no they are not all the same. Many have the same specs but there are also many that whichever battery giant like Energizer for example has huge contracts to have their cells manufactured to higher standards.
What is a cr123 battery?
CR123A batteries are compact, lightweight cells with relatively large voltages. This makes them ideal for applications that require tons of power while maintaining a small package. Their bright flashes, LCD displays, and various other functions required the high voltage provided by lithium chemistry batteries.
