Caldwell E-MAX Pro Lithium-Ion Rechargeable Battery Pack

The Caldwell E-MAX Pro Rechargeable Lithium-Ion Battery Pack is an official replacement and spare power source for the Caldwell E-MAX Pro Bluetooth electronic hearing protection earmuffs. It offers a clean, rechargeable alternative to disposable AAA batteries, allowing extended range sessions without scrambling for fresh alkalines.

This compact pack delivers 3.7 volts of power and provides up to a 16-hour runtime on a single charge, enough to cover full days at the range or in the field. It installs directly into the earmuff battery compartment, securely seating in the E-MAX Pro housing for reliable contact throughout use.

Finished in a high-visibility yellow color for quick identification among other range gear, the pack measures 1.25" in diameter by 1.75" in length for a snug fit inside the muff. This replacement battery is ideal for shooters who already own a pair of Caldwell E-MAX Pro Bluetooth muffs and want to keep a charged spare on hand, or who need to swap out a depleted pack after years of service.
