![]() ![]() At moderate to high discharge rates, the voltage of alkaline batteries drops rapidly, making them unsuitable for use in high-output flashlights. Better Voltage Maintenance A lithium battery maintains fairly constant voltage for up to 95 of its life, depending on discharge rate. These LFP rechargeable batteries have significantly less run time than their disposable counterparts. SureFire 123A batteries generate 3 volts. Charge termination occurs at 3.65V typical Every SFLFP123-KIT includes two Lithium Iron Phosphate (LiFePO4) 450mAh 3.2V rechargeable batteries, a two-bay battery charger, and a MICRO-USB to USB-A cable.ġ/4 USB Input 5V/1A, Output 400 mA, 2x 200 mAġ/4 Smart, internal circuitry automatically terminatesĬharge cycle when batteries are at full capacityġ/4 Safety design features provide protection from overcharge, short-circuit, and reverse polarityġ/4 Charge one or two SFLFP123 from 1.5 hours to 3 hours. Power SureFire and other LED flashlights with this two-pack of SFLFP123 Rechargeable Lithium Phosphate Batteries. The included smart charger can fully charge two batteries in three hours, in the convenience of your home, office or vehicle. Safe to use and cost- effective, SFLFP123 batteries retain approximately 80% of their original capacity even after hundreds of charging cycles. The SFLFP123-KIT is the perfect solution for customers who prefer to use rechargeable 123A batteries when powering SureFire illumination tools, including WeaponLights and hands-free lights. Includes two-bay charger for easy, convenient recharging at home or on the go. ![]() SFLFP123 batteries are better for the environment because they contain no hazardous heavy metals. Lithium batteries greatly outperform alkalines over a wide temperature range, providing a working output from -76º to 176º F (-60º to 80º C).SFLFP123 batteries are rechargeable and reusable, saving you hundreds over 123A lithium primary batteries. Stored alkalines deplete themselves much more rapidly. Lithium batteries can retain up to 90% of their original power output capability after 10 years of storage, making them perfect for emergency preparedness use. These are designed to be used in place of their primaries. The new Surefire rechargeable batteries utilize a different chemistry and are only 3.2 volts (I think). Typical rechargeable 123s (RCR123as) are 3.7 volts (4.2 volts fresh off the charger). At moderate to high discharge rates, the voltage of alkaline batteries drops rapidly, making them unsuitable for use in high-output flashlights. To expand on Robins comments - Surefire primary batteries (123As) are 3.0 volts. Made in the USA from US and imported parts. Wide temperature tolerance prevents degradation when in use or when stored. BALDY CIRCLE FOUNTAIN VALLEY, CA 92708-6122 SUREFIRE. High-performance batteries optimized for high-drain use in flashlights. MICRO USB CHARGE RECHARGEABLE LITHIUM ION 18650 BATTERY USER MANUAL 18300 MT. Alkalines, just 1.5 volts.Ī lithium battery maintains fairly constant voltage for up to 95% of its life, depending on discharge rate. Repairs Department, RMA 17680 Newhope Street, Suite B Fountain Valley, CA 92708 SureFire will pay reasonable shipping costs to return the unit to you. Ive bought them directly from Surefire, and from a guy I see at gun shows. SureFire 123A batteries generate 3 volts. the other brands ive tried, including by people that are supposed to be good on regular batteries, turned out to have really poor performance and life compared to Surefires. We use them instead of standard alkaline batteries because of their many advantages, such as:įor a given size (battery volume), It would take two alkaline batteries to match the power output of a single SureFire 123A lithium battery.įor a given size (battery volume), Lithium batteries weigh about half as much as alkalines but produce more power. In fact, Surefire pioneered the use of these compact, lightweight, energy-dense devices in flashlights. These batteries are safe to use, cost-effective, and they retain approximately 80 of. Made in the USA to SureFire specificationsĪlmost all SureFire illumination tools are powered by disposable 123A lithium batteries. The Surefire Rechargeable Battery CR123A 3.2 Volt Lithium Pack of 2 with Charging Kit is the perfect solution for customers who prefer to use rechargeable 123A cells when powering SureFire illumination tools, including weapon lights and hands-free lights.Built-in heat and fault (short-circuit) protection.TheSureFire CR123 Lithium Batteries, unlike alkaline batteries, boast a ten-year shelf.
