Rayovac Ultra Pro AAA Batteries 24-Pack vs Energizer EN92 Industrial AAA Batteries

Both are 24-packs of 1.5V alkaline AAA cells with 10-year shelf life, so the choice comes down to small margins. The Energizer EN92 has a slight edge on rated capacity and cold-weather range, and its 6 inner boxes of 4 make storage and carrying easier. The Rayovac Ultra Pro is a solid, widely trusted contractor pack that runs fine in remotes, clocks and flashlights. Buy the Energizer for cold outdoor use or if you want smaller sub-packs; buy the Rayovac if you already know and like the brand.

• Choose the Rayovac Ultra Pro if you want a familiar contractor-pack AAA that handles household remotes, clocks and flashlights and you prefer one close-able container over inner boxes.
• Choose the Energizer EN92 if you need better cold-weather performance or want the 24 cells split into 6 boxes of 4 for toolbags and drawers.
