No. A pack of 36 batteries is ranked right alongside packs of 100 batteries, so compare the price per battery, not the pack size or the sticker price.

Why compare AAA batteries by price per unit?

Packs come in many counts, so the total price tells you little. Dividing by the number of batteries puts every pack on the same scale.

Cheapest AAA Batteries Per Unit in November 2026

The cheapest AAA batteries on our list right now are PKCELL AAA Batteries 100 Pack, Triple A Batteries at $0.18 per battery, checked on October 29, 2026. Here is how the top 5 stack up and how to read them.

What is the cheapest AAA battery per unit?

This is the current ranking, lowest price per battery first:

PKCELL AAA Batteries 100 Pack, Triple A Batteries: $17.99 for 100 batteries, or $0.18 per battery
Varta Longlife AAA Batteries (100 Pack), Alkaline Triple A…: $19.32 for 100 batteries, or $0.19 per battery
NXbettery AAA Battery, Alkaline Battery High-Performance…: $6.99 for 36 batteries, or $0.19 per battery
PKCELL AA Batteries & AAA Batteries 48 Count, Double A…: $9.99 for 48 batteries, or $0.21 per battery
DURNERGY AAA Batteries 100 Pack Alkaline 1.5V 10 Year Shelf…: $23.98 for 100 batteries, or $0.24 per battery

Notice how tight the spread is at the top. The gap between first and second is small, so a modest price change can swap them. Treat the top few as a group, not a single winner.

Is a bigger pack always cheaper per battery?

No, and this is where people overpay. One of the packs above holds 36 batteries and still sits close to packs of 100 batteries on unit cost. Meanwhile another 100 batteries pack lands at the bottom of this list. Bulk helps only if the per-battery math works out.

Also, a low unit price is not a reason to buy 100 batteries if you will never use them. AAA cells sit fine on a shelf for a while, but a huge box you stash and forget is money you could have kept.

How do I compare AAA battery packs fairly?

Do the same few checks every time:

Divide the total price by the number of batteries. That is the only number that matters for comparing packs.
Confirm the size is AAA. Some multipacks mix AA and AAA cells, which changes how many AAA batteries you actually get.
Check the chemistry in the listing. Alkaline is the usual choice for remotes, clocks and flashlights, while rechargeables cost more up front and make sense for heavy-use gear.
Look at the count in the title against the count in the details. Listings sometimes disagree.

The same price-per-unit approach is explained in how the ranking works, and you can see every ranked pack on the full AAA comparison.

Before you buy

Cheap batteries are fine for low-drain devices like TV remotes, wall clocks and thermometers. For anything that drains fast, like a camera flash or a gaming controller, a lower price per battery can cost you in swaps, so consider rechargeables there.

Prices on batteries shift often, and a pack that is cheapest today may not be next week. Open the live list before you order, and check the pack count at checkout. If you want the lowest price across the category, start with the lowest price list.
