Frequently asked questions

Why do bigger packs usually cost less per battery?

Sellers often price larger multipacks lower per battery, and you can check that for 9V batteries on this page: compare the price per battery across pack counts in the table and in the pack-count chart. It does not hold for every listing, so rely on the figure rather than the pack size alone, and remember that a big pack means buying more batteries than you may use soon.

How do alkaline, lithium and rechargeable batteries compare on price per battery?

The chemistry column and the chemistry chart show each group's price per battery for the listings on this page. Single-use alkaline listings usually come out lower per battery than lithium or rechargeable ones, but a rechargeable battery can be used again, so its price per battery is not a like-for-like figure with a single-use cell. How many times you would recharge it is up to you, and we do not measure it.

Does the same 9V battery fit every device?

The 9V block has the same snap connector across brands, but a device may specify a chemistry, and some smoke alarms ask for a particular type. Check the device manual; this page only compares price per battery.

How much do 9V batteries cost per battery?

Across 114 listings, the middle 80% range from about $1.25 to $7.37 per battery, with a median of $3.19. Prices change often, so check the current price on Amazon before you buy.

Which of the 9V batteries has the lowest price per battery right now?

At the last update it is 24 Pack 9V Batteries 9 Volt Battery for Smoke Detector Guitar Garage Door Ope..., at $0.83 per battery. The cheapest listing is not always the best buy: compare the chemistry, the pack count and the seller before you order.
