Duracell Duralock Copper Top AA Alkaline Batteries - 60 Pack | Long-Lasting Power for Toys, Flashlights & Electronics | Premium Alkaline Battery for Home & Office Use

I used to buy a brand starting with "R" but switched to Duracell and take pride in making the switch. Have not found any bad battery yet, lasts very long in most devices. Considerably economical compared with blister pack sold in retail stores but works the same. Family of four consumes 40-60 AA and AAA batteries in 6 months being used in multiple household devices, it saves money and lasts VERY long time.
