How We Determine the Best Alkaline Batteries
Understanding battery testing helps you make informed decisions. Here's what matters:
Testing Methodology
We've identified the best alkaline batteries on the market by rigorously testing a wide range of models and brands. Our thorough evaluation involved extensive discharge tests to identify the longest-lasting alkaline batteries, including AA, AAA, C, D and 9-volt options. Furthermore, we analyzed the cost per battery for each choice, ensuring that you receive exceptional value for your investment.
Professional testers use sophisticated equipment. We test all alkaline batteries using an Ansmann Energy XC 3000 battery tester. Using this, we first test that the batteries have a starting voltage of t least 1.5V. Next, we measure capacity in mAh (milliamp hours), which is a standard rating for batteries. Our battery tester discharges batteries with a 600mA load (+/-20%) and stops when the voltage hits 0.94V.
What Capacity Numbers Really Mean
Capacity, measured in milliamp hours (mAh), tells you how much energy a battery stores. Think of it like the size of a gas tank—bigger capacity means longer runtime. However, the capacity of an alkaline battery is strongly dependent on the load. An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh.
This is why the same batteries perform differently in various devices. A battery that lasts months in your TV remote might only power your digital camera for a few hours. It's not the battery's fault—it's just physics.
High-Drain vs. Low-Drain Devices
High-drain tests measure how long batteries last in the most power-hungry devices. Examples include digital cameras and high-powered torches. Medium-drain tests mimic items such as video-game controllers, which consume moderate amounts of energy with continued use. Low-drain tests show how batteries last in devices such as clocks and smoke alarms – these use a small and steady amount of power over a long period.
High-drain devices:
- Digital cameras
- Motorized toys
- High-powered LED flashlights
- Wireless gaming controllers
Low-drain devices:
- TV remotes
- Wall clocks
- Smoke detectors
- Thermometers
For high-drain devices, premium batteries like Duracell Plus or Energizer Ultimate Lithium make sense. For low-drain devices, budget options like Amazon Basics work perfectly fine.
Brand Comparison: Who Makes the Best Alkaline Batteries?
Let's break down the major players in the alkaline battery market.
Energizer: Consistent Performance Leader
Energizer (who also makes Eveready) just edged out Duracell in our rankings, but they could easily have been reversed. Mostly, though, Energizer's products across the entire spectrum of AAs — from alkaline to Lithium-ion — tend to perform well. Energizer Ultimate Lithium batteries and NiMH Energizer Recharge batteries stood above and beyond the rest, while Energizer as a brand, as a whole, found their way to the top of the battery bunch.
Energizer often leads in performance tests, especially in high-drain devices. Users frequently praise its ability to maintain consistent power output over time. The brand's commitment to innovation shows in products like their EcoAdvanced line, made with recycled materials.
Duracell: The Trusted Household Name
Duracell stands as a powerhouse in the battery industry. Known for its reliability, Duracell has earned the trust of consumers worldwide. The brand's reputation stems from its ability to deliver consistent power across various devices. Whether it's remote controls or high-drain gadgets, Duracell batteries perform exceptionally well.
Duracell also makes Kirkland batteries for Costco. It might still surprise a few people that Costco's own brand Kirkland makes a set of AA batteries that've appeared near the top of test results. And it shouldn't surprise anyone that Kirkland batteries are made by Duracell. This means you can get Duracell quality at Costco prices.
Rayovac: Underrated Value Brand
Rayovac – Focused on delivering affordability and durability, ideal for budget-conscious consumers without sacrificing performance. While testing shows mixed results depending on battery size, Project Farm rated Fusion highly for capacity, and they get top consumer ratings at Lowe's and Home Depot. The duration testing done by Cinema Sound shows them to be the second best alkalines, being edged out by Energizer Max.
Interestingly, the performance of a manufacturer's AAA alkaline batteries is in no way predictive of the performance of a manufacturer's AA alkaline batteries. As an example of that, Rayovac makes some of the lowest-capacity AAA alkaline batteries but some of the highest-capacity AA alkaline batteries. This means you need to evaluate each size separately.
Voniko Batteries: Quality You Can Trust
When shopping for alkaline batteries, consider Voniko. This brand offers reliable performance at competitive prices, with a focus on quality manufacturing and long shelf life. Voniko alkaline batteries deliver consistent power for both high-drain and low-drain applications, making them versatile for everyday use.
How to Make Your Alkaline Batteries Last Longer
Getting the most out of your batteries isn't just about buying the right brand—it's also about how you use and store them.
Proper Storage Matters
Store them in a cool, dry place at room temperature, avoiding extreme temperatures and especially humidity. Proper storage helps maintain their performance over time. Always take batteries out of toys and electronics you don't plan on using for a long time.
Premium alkaline batteries generally maintain 80–90% capacity for 5 to 10 years when stored correctly. For instance, Duracell guarantees a shelf life of up to 10 years under recommended conditions, and Energizer MAX claims similar longevity.
Storage tips:
- Keep batteries in their original packaging until needed
- Store at room temperature (59°F-77°F / 15°C-25°C)
- Avoid humid environments
- Don't store in freezers (this doesn't help and can cause condensation)
- Keep away from metal objects that could cause short circuits
Match Battery to Device
For devices with lower energy demands, such as remote controls and clocks, alkaline batteries are often the best choice. Always choose lithium or NiMH for high-power devices and alkaline for low-power devices to ensure optimal performance and efficiency.
Using premium batteries in low-drain devices wastes money. Save your Duracell Plus batteries for digital cameras and gaming controllers. Use budget alkalines for TV remotes and wall clocks. This smart matching maximizes value.
Remove Batteries from Unused Devices
Alkaline batteries typically have a shelf life of several years, but it's important to check the expiration date on the packaging. Even quality batteries can leak if left in devices too long. If you won't use a device for several months, take the batteries out. This prevents corrosion damage to your electronics.
Buy in Bulk When Prices Are Good
Bulk buying saves money, especially for batteries you use regularly. Larger pack sizes provide particularly good economy. Amazon Basics, Costco's Kirkland, and other store brands often offer excellent bulk deals. Just make sure you'll use them within their shelf life.
Battery Performance Claims
Marketing claims can be confusing. Here's what you need to know:
"Long-Lasting" Doesn't Always Mean Better
We were stunned to discover that by no means are Duracell ProCell batteries "the best" alkaline battery. In fact, they're sort of in the bottom of the average. Worse, it was clear that regular Duracell batteries lasted longer by over 31%! This shows that fancy marketing names don't always translate to better performance.
The lesson? Don't pay extra for batteries with premium-sounding names without checking independent test results. Regular versions often perform just as well or better.
Lithium vs. Alkaline: When Does It Matter?
Overall, the tested lithium batteries performed much better than the alkalines, especially in cameras, which tend to drain a charge quickly. But alkalines cost far less, and some perform almost as well as lithiums in low-drain devices such as flashlights and remotes.
For most everyday devices, quality alkaline batteries work great. Save lithium batteries for extreme temperatures, very high-drain devices, or situations where you need maximum longevity.
Recycling and Environmental Considerations
Being responsible with battery disposal matters. While alkaline batteries are safer than some alternatives, proper recycling helps the environment.
Alkaline batteries contain zinc (Zn) and manganese dioxide (MnO2), which is a cumulative neurotoxin and can be toxic in higher concentrations. However, compared to other battery types, the toxicity of alkaline batteries is moderate. Many communities now accept alkaline batteries in regular trash, but recycling is better when available.
Check out Voniko's recycling guide for complete information on how to properly dispose of alkaline batteries. Responsible recycling reduces environmental impact and recovers valuable materials.
Frequently Asked Questions
Which alkaline battery brand lasts the longest in 2025?
Based on extensive testing, Energizer Max AA batteries offer the best combination of longevity and value for most applications. For maximum capacity, GP Ultra AA batteries topped capacity tests with an average of 1680.5mAh. However, the "best" battery depends on your specific device—high-drain devices like cameras benefit from premium batteries, while low-drain devices like remotes work fine with budget options.
Are expensive alkaline batteries worth the extra money?
Not always. Testing shows that mid-priced batteries often outperform premium options. Amazon Basics batteries, for example, delivered capacity within 10% of Duracell Plus at a fraction of the cost. For low-drain devices, budget batteries work great. Save premium batteries for high-drain applications where the performance difference justifies the extra cost.
How can I tell if my alkaline batteries are still good?
Fresh alkaline batteries should measure 1.5-1.6V when tested with a multimeter under no load. However, even dead batteries can show acceptable voltage without a load. The best test involves using the battery in the actual device. If performance is poor, replace them. Check expiration dates—most quality alkaline batteries last 5-10 years in storage. Physical signs like leakage, swelling, or corrosion mean immediate replacement.
Do alkaline batteries really last 10 years in storage?
Yes, premium alkaline batteries from brands like Duracell and Energizer can maintain 80-90% of their capacity for up to 10 years when stored properly. This requires storage at room temperature (59°F-77°F) in a cool, dry place, kept in original packaging. Temperature extremes and humidity significantly reduce shelf life. Budget batteries may have shorter shelf lives around 5-7 years.
Should I use alkaline or lithium batteries for my digital camera?
Lithium batteries significantly outperform alkaline batteries in digital cameras due to the high power draw. Consumer Reports testing found that top-rated Energizer lithium batteries took 609 shots compared to the best alkaline battery's 76 shots. For cameras, the higher upfront cost of lithium batteries pays off with much longer runtime. Use alkaline batteries for low-drain devices like TV remotes and wall clocks where their lower cost makes more sense.
