Comparing Different Priced AAA Batteries

This is not about Web Design or Web Development. But I thought others might benefit from my experiment.

I have often wondered when buying household batteries if it made more sense to pay more or less for the different brand options, especially when some batteries cost twice as much per battery.

Should I buy the cheaper batteries?

So I put AAA batteries from different brands into two identical flashlights and let them run. One flashlight lasted a little over 2 weeks and one lasted for 6 days.

Batteries both purchased from Amazon.

Energizer AAA Batteries (48 Count), Triple A Max Alkaline Battery for $19.49. Cost  40.6 cents each. Flashlight lasted 16 days. Value of 3 batteries = 7.6 cents per day.

ACDelco 100-Count AAA Batteries, Maximum Power Super Alkaline Battery, 10-Year Shelf Life, Recloseable Packaging for $23.99. Cost 24 cents each. Flashlight lasted 6 days. Value of 3 batteries = 12 cents per day.

Energizer AAA Max Batteries Win by a wide margin.

Obviously this is an isolated case and experiment and so one could not conclude that the more expensive batteries are always a better value. My main takeaway is that in the case of these household type batteries, less expensive per-battery cost does not necessarily equate to a better value.

Let me know if you have had any experiences with comparing batteries and what you have discovered.

    Asalam Alaykum Yunus –

    LOL, I’ve found another battery nerd!

    I have converted about 90% of my AA and AAA battery needs to rechargeable NiMH. Eneloop is the best brand, made in Japan. They can sustain high-powered draws, recharge in a few hours and will hold 90% of their charge after 1-year in storage or up to 80% charge after 10-years in storage. You can get a 4-pack of AA with a charger for about $18 on Amazon. Or if you already have a charger, you can get an 8-pack for about the same price. Similar for AAA. Over the life of the battery, you will end up paying less than $0.01 per charge and is better for the environment due to re-use instead of re-cycle.

    Also, I see you’re using these in flashlights. Well, if you want to go down another rabbit hole, you might like to look into the higher end flashlights. Some are not expensive. The Convoy C8 is about $20, runs on a rechargeable 18650 lithium-ion cell and is insanely bright. I don’t use it all the time, because it’s usually too bright, but it’s very handy at times. If you want to try a headlamp, checkout the Thrunite TH20, which is about $30 and runs on a single AA (or Eneloop) or a single 14500 (li-ion, brighter). If you want the most energy efficient flashlight or headlamp available, look into the line of the Zebralights. They’re really great lights, great for backpacking trips, but they will also make your wallet lighter, too, lol! I expect the Convoy, Thrunite and Zebralight to be the last flashlights I need to buy for about 20 years, if not longer.
