Hey @Eddie P
Love my Novatac, I run an ancient AW batt in mine too! Remember, when switching from a primary batt to a rechargeable, there's a "battery-detect-reset" you do so the light works best with the battery in it...
From the manual: "Installing a New BatteryUnscrew the battery compartment at the head or the button cap.Insert a new battery into the battery compartment so the positiveterminal is toward the front of the light. Be sure both the headand button cap are screwed on snugly. If the battery is insertedbackwards the light will not turn on.A rechargeable battery must be fully charged before installation.When changing to or from a rechargeable battery a Battery-DetectReset is required.Battery-Detect-Reset1. Turn the light on.2. Unscrew the battery case until the light turns off.3. Screw the battery case back together; there will be onesecond of dim light.4. During the one second of dim light, press and hold the button.5. You will see five Mine seconds of bright light, followed by dim light.6. Release the button when the light goes dim.7. The Battery-Detect-Reset is complete.If the button is released during the brighter light period, the ErrorFlash Sequence of six rapid flashes will be displayed. The light willnot detect the new battery configuration and damage may occur to the rechargeable battery."
Yes I noticed it was quirky if you did not do it right. Yours takes 2 batteries correct?Hey @Eddie P
