CR123 Batteries


CR123 or Cr123a lithium battery is a 3 volt lithium battery used in camera flashes, LED bright flashlights, Gun scopes and other various devices. The cr123a lithium battery is a powerful small battery made by many different manufactures.  Some of the best brands Are Duracell, Panasonc and Energizer. Another very common name for the Cr123a battery is Cr17345 battery. 


One of the most common phone calls I get about the cr123 battery is people asking if the cr123 and cr123a battery are the same. The answer is yes it is and it can be interchanged with any cr123a or cr123 battery. Some cr123a batteries go in a tight compartment and different manufactures may make the battery to different size specifications. Another very common name found on a cr123a batteries is 17345 or DL123 or El123 these are all names from different manufactures for the exact same size battery. Some of the off brand batteries have lower capacity then the big sames such as Energizer and Duracell.

The cr123a battery has a rechargeable version which is the RCR123 battery but the power of the battery is only 70% of the non rechargeable cr123a batteries. If you are using cr123a batteries for back up alarms we suggest using one of the major brands.

When purchasing cr123a batteries keep in mind that buying them off the shelf at stores like Wal-Mart, Target or any other major retailer can be pretty expensive. Buying them in bulk can yield you a huge savings and you want to seriously consider that option. Always be sure to buy fresh date codes as these batteries should have a 10 year shelf life.

There are many brands that are manufactured in China sold under other names such as Titanium, Powerizer, Tenergy and should be priced about 1/2 the cost of any other big name like Duracell, Energizer and Panasonic. They are great alternatives but the quality is simply not the same. Most of the new hi tech L.E.D flashlights use the cr123a batteries and that’s because of it high voltage high output it offers.

The bottom line is we know that some customers want the very best when it comes to batteries and for them the Duracell, Energizer and Panasonic is the way to go, for the other customers who want the cheap batteries to get by those would be the off brand batteries that come out of China.
