Are CR123A and 16340 the same?

The 16340 battery (or RCR123A) is a cylindrical li-ion cell classified by its 34mm x 16mm dimensions, and is the rechargeable version of a CR123A battery. They usually have a 3.6V or 3.7V voltage, button-top terminal, and most use a LiCoO2 (lithium carbon-oxide) chemistry.

Is CR123A the same as rl123a?

According the the cross reference guide on rayovacs site the rl123a is the same as the cr123a.

Can 18650 battery replace 2 CR123?

Don’t worry. These batteries are all interchangeable, and there is no operational difference between them. They are all lithium chemistry batteries with a nominal voltage of around 3.0 volts and a capacity ranging around 1000-1500 mAh. I have found the most common designator for these batteries is CR123A.

What does CR mean in CR123A battery?

If I understand, the 123A designates the battery as one battery that is 2/3rds the size of an “A” size battery. Correct? “CR” is the chemical symbol for chromium, is chromium somehow used in making a 123A battery? Do they still make “A” size batteries?

Is 18650 the same as 2 CR123A?

They will often last for 800-1000 recharge cycles under optimum conditions when they are taken care of, but in all honesty real-world use is more likely to see 300-500 cycles. The 18650 battery is almost exactly the same length as two CR123A or 16340 batteries. It is approximately 2 mm thicker.

Is 18650 same as CR123?

18650 is a bit thicker and about as long as 2 CR123s, with higher voltage. 18650 is rechargeable, CR123 is primary. They make similarly sized rechargeable cells usually called RCR123. Rechargeables have about half as much power as a primary, but are rechargeable.

Is CR123 the same as 123?

So the 123 battery is often called CR123, CR123A, 123A, DL123, DL123A, EL123 or EL123A. The DL in the part numbers DL123 or DL123A simply stands for Duracell. These Duracell DL123A lithium batteries have a long shelf life of around 8 years.
