List of battery brands that include the most reliable models available. Top battery brands include those from major manufacturers of batteries including Energizer, Duracell, Panasonic and more. In strict terms, a battery is a collection of multiple electrochemical cells, but in popular usage battery often refers to a single cell.
Shop around for AA and AAA batteries and the main types you’ll find are alkaline and lithium disposable batteries. Lithium batteries last a lot longer in more energy intensive devices. We've found that they can give you 2-3 hours more power than an alkaline battery. But they're also much more expensive.
Standard battery sizes include AA batteries (or "double A"), which account for over 50% of general battery sales, AAA ("triple A") and D batteries. Miniature batteries, rechargeable batteries and standby power centers are other types.
CinemaSound rated the cost per hour for Fuji's EnviroMax AA at the highest of all alkaline batteries they tested, edging out the Duracell Procell. Fujitsu is slightly more consistent in the sense that the battery brands we considered were almost all around the bottom of the pack, with the strange exception of the Fujitsu Universal Power AA.
Since AA and AAA are the most commonly used household batteries, we focused primarily on those sizes for this guide. To find the best ones, we scanned well-known retailers like Amazon, Home Depot, and Walmart to get a feel for the most widely accessible brands of rechargeable AA and AAA batteries.
Duracell AA: Highest price per unit, but the second-best performer and a close contender for the best pick. Rayovac AA: Second most costly AA battery with moderate performance. Not necessarily the top option available. Amazon Basics C: Lowest price per unit among C types, significantly cheaper than the competition. A good choice for bulk purchases.
