AA batteries, a cornerstone in the world of portable power, have long been the go-to source of energy in a myriad of devices (including holiday toys, of course). Their standardized size of 50.5 mm in length and 14.5 mm in diameter and voltage of 1.5 volts have made them a versatile choice for a wide range of applications, from everyday household items to more demanding technological devices.

Though the dimensions are standardized, AA batteries are not all alike. A significant benefit of AA batteries is their availability in various chemistries, each catering to different needs and applications. The most common types include alkaline, lithium, and rechargeable NiMH (Nickel-Metal Hydride) batteries:

  • Alkaline batteries are widely favored for their affordability and decent energy density, making them suitable for low to moderate-drain devices.

  • Lithium AA batteries, on the other hand, offer a higher energy density and a longer shelf life, making them ideal for high-drain devices and extreme temperature conditions.

  • Rechargeable NiMH batteries, while initially more costly, provide the benefit of repeated use over time, making them an eco-friendly and cost-effective solution for frequent power users.

The enduring popularity of AA batteries can also be attributed to their economic and practical advantages. In terms of cost, AA batteries are generally affordable and offer a favorable balance between price and performance. Their single-use design and ease of replacement make them convenient for consumers, ensuring that devices can be kept running with minimal interruption. Additionally, the global standardization of AA batteries means they are readily available almost anywhere in the world, further enhancing their appeal to a wide demographic.

Since it's the holiday season, we’ve decided to put together a list of the most popular AA batteries on the market right now. Read on to learn about seven of the most popular AA batteries that you can buy.
