Although the long shelf life and leak-free guarantee are good to see, in my tests, the Energizer Max AAA delivered less capacity at a higher price than the competition. Given these results, there are better options to be had.
- Long shelf life
- Leak-free guarantee
- Wide choice of pack sizes
- Lower capacity than rivals in my test
- Better value options are available
- UKRRP: £4.99
- Battery typeThese are AAA alkaline (non-rechargeable) batteries
From second-best-known-name in batteries, the Energizer Max AAA are designed for long-lasting applications and are guaranteed against leaks for up to two years after fully used.
Readily available and in a wide-range of pack sizes, these batteries can be picked up for a decent price, but they lagged behind other AAA batteries in my tests.
- Overall capacity behind the competition in my tests
- Weak initial high-drain test
Energizer says that its Max AAA batteries have a shelf-life of 10 years, and are leak-free for up to two years after being fully used. Based on the company’s data, when discharged to 0.8V, the batteries have the maximum capacity when used with a lower load.
I tested these batteries using an Ansmann Energy XC 3000. First, I tested the starting voltage of the batteries, which should be around 1.5V for alkaline batteries. Measured at 1.52V, these batteries were ideal out of the box, which I bought from Amazon.
I picked four random batteries for my high drain test, which uses a current of 600mA (+/- 20%) and a cut-off voltage of 0.94V. After the initial test, I measured capacity at 269mAh, which is off the pace set by rivals, such as the Amazon Basics Alkaline AAA, or the Duracell Plus AAA.
I give batteries a couple of hours to rest and cool down, then re-run the test to measure the resulting capacity. Here, the batteries returned a measured capacity of 136mAh, giving me a total measured capacity of 405mAh.
This suggests that these batteries are better off in low-drain tasks, such as remote controls, rather than high-drain tests such as powerful torches or grooming equipment.
The Energizer Max AAA batteries are available in lots of different pack size, ranging from around 63p per battery down to around 59p per battery I’ve listed the price of the 8-pack here (around 63p battery), as it offers a good compromise between price and pack size.
Should you buy it?
If you want batteries that are guaranteed leak-free, these could be a good choice for you.
With low measured capacity in my tests, there are better-performing batteries that cost less.
Although they can be bought in good-value packs, my tests show that these batteries are a little off the pace of the competition. The Amazon Basics Alkaline AAA batteries can be bought cheaper and did better overall in my tests.
How we test
Unlike other sites, we test every alkaline battery we review thoroughly over an extended period of time. We use standard tests to compare features properly. We’ll always tell you what we find. We never, ever, accept money to review a product.
Find out more about how we test in our ethics policy.
We use an Ansmann Energy XC 3000 to drain batteries, so that we can test capacity in mAh. After the first run, we allow the batteries to cool and then retest to give us a second reading.
We measure the initial voltage of the batteries, checking that the starting voltage is at least 1.5V.
