Default Rechargeable Battery Size Comparison Explained

.

(Appearently there is a color issue w/ this post if using the lighter colored skins. The system isn't converting the colors for the other skins. I have been working to fix this, but made it worse I hear. I do not know how to switch skins or what they are each called, but this is best viewed on the darker background skin for now. Or you can highlight everything while using the other skins to see it all. I will hopefully get this correct shortly. Thanks!)

* * * * * * * * * * * * Hey Everyone,
* *
* * * * * * * * * * ** * * ** * ***:

* Ever wonder what size rechargeable battery will fit into your "AA" housing?
Or which one could you substitute for two CR-123a's?

Well, your looking is over!
Below is a great and simple explaination of the sizes of rechargeable batteries and what the numbers mean.


* * * * * * * ** * Enjoy!

* * * * * * * ** *****8-)


* * * Size Chart,

This is a chart that illustrates the approximate sizes of the various rechargeable lithium batteries.
The numerical designation of the battery gives an approximation of the size.

For example, a 10280 battery is approximately 10mm in diameter and 28mm tall, the final 0 indicates that it is round.

Please note that the sizes are approximate, and some batteries, especially protected batteries, may be too large to fit your particular application, please check the exact sizes.


10180 battery - 10mm x 18mm (1/3 AAA size)

10280 battery - 10mm x 28mm (1/2 AAA size)

10440 battery - 10mm x 44mm (AAA size)

14250 battery - 14mm x 25mm (1/2 AA size)

14500 battery - 14mm x 50mm (AA size)

16340 battery - 16mm x 34mm (nominal CR123a size)

17335 battery - 17mm x 35mm (nominal CR123a size)

17500 battery - 17mm x 50mm - slightly wider than CR-123, fits most lights, but 1.5 times the height of the typical CR-123a battery - two of these will generally replace three of the CR-123a batteries

17670 battery - 17mm x 67mm - about the size of two CR-123a batteries, but less overall voltage, 4.2v max vs. 6v max from two primary batteries

18500 battery - 18mm x 50mm - wider than CR-123a, about 1.5 times the height of a single CR-123a battery, these will only fit lights designed for their wider size

18650 battery - 18mm x 65mm - wider than CR-123a, about 2x the height of a single CR-123a battery, these will only fit lights designed for them


...Thanks All, Hope This Helps...

* * * * ** * Regards, Joe

Could I suggest a slight mod to the above.
For quick reference could you put the voltages on?

Very useful...

Good information, but you may want to keep in mind that many people these days have likely never seen an 'A' size battery unless they're working with very specific or older equipment.

I think all are 3.6V nominal. *You can get some, I think the CR2 and CR123A, in 3V too.

Default Re: Rechargeable Battery Size Comparison Explained

Just a reminder to be careful mixing up voltages with battery sizes.

There are a few different Lithium chemistries and they have different voltages. They can be very sensitives (a fraction of a volt) to overvoltage and undervoltages. If a mistake is made (especially during charging), the results can be disasterous - rapid venting (of toxic fumes) with flame. Wouldn't want to burn your house down - while charging a bettery.
