    Battery Safety Precaution

    Ensure the protective circuit on the 18650 batteries has current limitation of higher than 5A. Always use proven EAGTAC batteries for best performance and reliability.

    All EAGTAC flashlights are designed to use button-top battery (battery with protruding positive terminal). For rechargeable li-ion battery, use only EAGTAC li-ion battery, or other protected li-ion battery with compatible length and diameter. Before using the battery, check and ensure the battery outer wrapping (the isolating plastic film that wraps around the metal housing of the battery) is complete. Broken battery wrapping may lead to short circuit and damage to the flashlight.

    Lithium and Li-ion battery can explode or cause burns if disassembled, shorted, or exposed to high temperature. Do not mix new and used batteries. Do not mix batteries with different brand, capacity, voltage, or install batteries backwards.

    NiMH rechargeable battery may release gas during discharge. If you experience an inflated switch boot or find high pressure being built inside the flashlight, switch off the flashlight immediately. Slowly loosen the tail-cap to reduce the internal pressure and replace all batteries.     Back to top

    Flashlight Maintenance

    Periodically clean the threads and o-rings with a lint free cloth and apply a thin coating of EAGTAC synthetic grease to the o-rings and threads. After prolonged exposure to moisture, the head and batteries should be removed, inspected, and dried. Do not touch or attempt to clean the reflector, as it will scratch the reflective coating permanently.     Back to top

    Other battery types runtime (MAX output)

    Sanyo Eneloop xx AAA 950mAh: 0.7hrs, Duracell alkaline: 0.3hrs, 10440 0.3hrs

    * When using 10440 li-ion, turn down the brightness when the light becomes too hot to touch.
    1. This weight measurement does not include batteries
    2. All batteries must have protruding top button.
    3. Beam output diameter taken at one meter
    4. ANSI FL-1 Lumens is a measurement of light output standardized by American National Standards Institute for use with flashlights. This ANSI Lumen measurement is the total overall light output being emitted from the flashlight. This measurement is generally more accurate as it takes into consideration the loss from reflector/lens/bezel. EAGTAC’s ANSI Lumen output is measured using a calibrated integrated sphere three minutes after turning on the flashlight. For O.T.F. lumen, measurement is taken one minute after turning on the flashlight.
    5. This lumen output and runtime is measured using Eneloop xx AAA 950mAh battery. Using 10440 li-ion at highest level will direct drive the LED at maximum output. Limit the operational time when using li-ion to prevent overheat.
    6. Runtime is measured with energy saving feature enabled using three EAGTAC 3400mAh batteries.
    7. Maximum efficiency occurs when input voltage is very close to LED forward voltage.
