Ready to say goodbye to button cells? We install a custom-designed PCB that powers your camera’s exposure system directly from the main AA batteries—eliminating button cells altogether and reducing the risk of corrosion.
 
Our 2.7-volt regulator slips seamlessly into the original button-cell terminal while drawing power exclusively from the AA batteries, permanently removing the hassle. Most cameras that originally relied on two button-cell batteries for exposure or metering are compatible with this upgrade.
 
The result is a steady, regulated 2.7 volts—the factory-recommended voltage—for consistent, accurate exposure. Unlike button cells that fade and drift over time, this system delivers stable voltage shot after shot for dependable, long-term performance.
