The RAYOVAC 813-2 GENK.01 is a 2-pack of D-size alkaline batteries built for sustained, reliable power in high-drain and everyday devices. These batteries use a mercury-free formula and are backed by a 10-year freshness guarantee, making them a practical choice for stockpiling in service vans, facilities, or supply rooms. Ready Power technology maintains charge during storage, so batteries are ready to perform when pulled from the shelf. Each unit delivers the standard D-cell voltage and capacity expected from an alkaline cell in professional and residential applications.
D-size alkaline batteries see regular use across a wide range of trade and facility applications, including flashlights, lanterns, emergency lighting, power tools accessories, HVAC remote controls, test equipment, and battery-operated timers or thermostats. The 2-pack format is suited for direct installation or keeping as a backup supply on job sites. This product is sold in a case pack of 12 units (each unit being a 2-pack), which is appropriate for wholesale supply and facility maintenance programs.
Designed as a standard D-size alkaline replacement battery suitable for any device requiring a 1.5-volt D-cell alkaline battery.
D-size batteries should be installed by aligning polarity markings with the device battery compartment before seating. Always power down or switch off battery-operated equipment before replacing cells. Dispose of used alkaline batteries in accordance with local regulations; do not incinerate or puncture cells. Store unused batteries in a cool, dry location away from metal objects that could cause short-circuit contact.
