Tenergy RCR123A Charger for LiFePO4Batteries

RCR123 batteries are incredible sources of reliable power. Not only are they compact and efficient, they're also rechargeable. But not just any charger can effectively charge this unique technology. That's why we're so excited about this Tenergy charger made specifically for LiFePO4 batteries.

Purpose-Built Charger

This powerful lithium-ion battery charger is built specifically for Tenergy's unique LiFePO4 RCR123 Battery. Smart charger technology automatically detects when a battery is fully charged and switches off the unit to prevent over-charging. Advanced technology also protects against overheating, short-circuits, and reverse polarity.

Full Charging Package

This charger includes an AC and DC power input so you can charge your Tenergy batteries at home, or in the car. Two bays can be used simultaneously or one at a time. Together with your Tenergy RCR123A's, this charger will be your total solution to powering your LED flashlight, digital camera or other high-powered, CR123-powered electronic devices.

  1. Great charger because it comes with car charger also.

    I'm a K9 officer and something that is always needed is a flashlight. With the charger I am able to keep batteries charged at home as well as In my K9 unit

  2. Excellent charger

    Posted by Jeff K on 6th Jan 2015

    I bought both the batteries and charger, and they work great. Follow the instructions, yes they are easy, and I had no problems whatsoever.

  3. defective!

    Posted by Unknown on 4th Jan 2014

    Unfortunately the gift we gave our son was defective and he is returning the product. The company's shipping of the gift was quick and dependable. We just received a dud!

  4. Left me in the dark

    Posted by Unknown on 11th Dec 2013

    I ordered this to charge batteries for my duty flashlight (Streamlight 600 lumens), which was costing way too much to operate now that I work nights. The charger display told me the batteries were charged but they lasted about a quarter of the time, leaving me in the dark. Not a fun place to be in law enforcement. I'm still not sure if it was the charger not getting juice to the batteries or just a pair of batteries that couldn't keep a charge. At any rate, pretty bummed.

  5. Economical solution

  8. Product is working as advertised.

    Posted by Jim on 20th Mar 2013

    It serves it's purpose. I haven't used the charger for a sufficient enought time to be critical.My short time use has been positive, however.

  9. Simple and Easy to Use

    Posted by CoastRange on 20th Mar 2013

    Perfect solution for my LED flashlight that takes the expensive CR123 batteries.
