As wonderful as eBay is as a resource for just about anything, it can also be a frustrating source of counterfeit and fake products. Let's look at the sad case of UltraFire, a Chinese battery brand that has become so closely associated with poor quality (and dangerous) fakes that it's impossible to recommend.
Ansmann's alkaline also get good reviews on Amazon, managing 70 percent 5-star reviews on its 20-pack. Rayovac always feels like a sort of legacy battery brand along the lines of Eveready, and probably would not have fared so well in our rankings but for the company's Fusion line, which enjoys a strong reputation among consumers and testers.
On the other hand, Consumer Reports gave CVS Health AA Alkaline batteries a poor score, but somewhat predictably found CVS Health MAX AA Alkaline batteries recommendable. PNP Depot's Lithium rechargeable got poor reviews at Lowe's, but near-perfect ratings at Home Depot.
Consumer.org.nz gave Panasonic's Extra Heavy Duty a "Don't Buy" rating, but gave it to all the other Carbon Zinc batteries as well. Otherwise, Panasonic cells did well across the boards, generally matching their capacity ratings and performing well.
While the 1300 mAh battery performed well, Jensen notes that 1300 mAh is a considerably low capacity for your average AA battery. On the other hand, the 2600 mAh battery (which tested at 2801 mAh) was at the top of the capacity rankings for all AA cells.
The warranty NAPA offers depends on the battery types, with its "LEGEND" range getting 18 months, some more premium options getting two years, and the high-end stuff getting three. Warranty may be an area where NAPA is lagging behind some competitors, as many do offer three years as standard on their mid-range batteries (as of late 2024). 9.
