Product Description

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. Compares to my Hella Off Road Lights!

    Posted by runner on 20th Mar 2013

    I use this light to travel rivers during the fall salmon run. The river can be very foggy and it is dangerous to run the river prior to sun up. To get to the best holes, first is key. This light helps me run the river to find the spots to fish before the other guys have a chance.

  2. Go Green - Recharge

  3. Compact and Fast

  4. States it's 3.0 volt but it's 3.2 volt

    Posted by Mark on 20th Mar 2013

    These are quoted as being a 3.0 volt but they are a 3.2 volt. Hopefully they don't have too much voltage fully charged for my flashlight.

  5. great for reusing these type of battery

    house/travel use. charges my cr123 flashlight batteries. great use in led flashlight, decent and bright in normal ones...

  6. Stop paying for expensive 123s!

    Posted by Brian on 20th Mar 2013

    I use this charger for my Streamlight PolyTAC LED, that I use in the security industry. It is very portable, lightweight, and even comes with a car charger. I've only charged the batteries a few times, that's why I said pro: charges fast and con: charges slow. It has gone both ways. However..... Regardless... It's a major, tiny investment :)

    Charger works very well with different brands of Protected batteries. No Problems

  10. Charged the batteries, but...

    Posted by Doug on 20th Mar 2013

    The batteries are for a small Surefire flashlight. I charged the batteries, but the flashlight doesn't work. I don't know if it's the batteries or a disfunctional bulb in the flashlight.
