LR44 batteries are sold at most drugstores, supermarkets, and electronics retailers, both in-store and online
LR44 batteries are small coin-cell batteries used in watches, calculators, hearing aids, and small electronic toys. You can find them at chain pharmacies like CVS and Walgreens, grocery stores with pharmacy sections, big-box retailers like Walmart and Target, and electronics stores. Online, Amazon, eBay, and the websites of those same retailers stock them. Prices vary by brand and pack size, so comparing a few sources before you buy usually saves money.
The battery itself is the same whether you buy one or ten — what changes is the per-unit cost. A single LR44 at a pharmacy might cost $3 to $5, while a pack of ten from an online seller might cost $0.50 to $1 per battery. If you use these batteries regularly, buying in bulk online is cheaper. If you need one today, a nearby drugstore is faster.
Key Takeaways
- Drugstores, supermarkets, and electronics retailers carry LR44 batteries both in physical stores and on their websites.
- Single batteries at pharmacies cost significantly more per unit than buying packs of ten online.
- Amazon and eBay often have the lowest per-battery cost, but delivery takes several days.
- Check the expiration date on the package, especially if buying from clearance bins or older stock.
- LR44, AG13, and SR44 are different chemistries; confirm your device manual before substituting one for another.
Drugstores and pharmacies stock LR44 batteries near the checkout or in the health aisle
CVS, Walgreens, and Rite Aid carry LR44 batteries in most locations. They are usually shelved near the front counter, in the pharmacy section, or in an aisle with other small electronics and batteries. A single battery or a small pack of two or four is typical. Prices are higher than online, but you can walk out with a battery the same day.
These stores also run sales and coupons. Check the store's app or website before you go — some offer discounts on batteries when you buy other items, or periodic promotions on battery multipacks. Expiration dates at pharmacy counters are usually current, but check the package anyway, especially if the battery has been on the shelf for months.
Supermarkets and big-box stores offer LR44 batteries at mid-range prices
Walmart, Target, and grocery chains like Kroger and Safeway stock LR44 batteries in their electronics or health sections. Prices fall between pharmacy counters and online sellers. Walmart and Target often carry multipacks of 4 or 10 at a better per-unit rate than single-battery pharmacy sales. These stores also have online ordering with in-store pickup, so you can order on your phone and collect the battery within hours.
Costco and Sam's Club sell LR44 batteries in bulk packs if you have a membership. The per-battery cost is among the lowest available, but you must buy a larger quantity upfront. If you use these batteries regularly or stock supplies for a household, membership-based bulk buying makes sense. If you need one battery once a year, it does not.
Electronics retailers and specialty shops carry LR44 batteries and related products
Best Buy stocks LR44 batteries in-store and online. Radio Shack locations that remain open also carry them. These retailers are useful if you are already buying other electronics or need information about which battery type your device requires. Prices are comparable to supermarkets, and staff can often confirm whether an LR44 is the right fit for your device.
Hearing aid retailers and watch repair shops also stock LR44 batteries, sometimes at higher prices but with informed guidance. If your device is a hearing aid or an expensive watch, the retailer who sold or services it may have the exact battery and can confirm it is the right type before you buy.
Online retailers offer the lowest per-battery cost but require planning ahead
Amazon, eBay, and Walmart.com sell LR44 batteries in packs ranging from 5 to 50 units. Prices per battery are typically $0.40 to $0.80 when you buy in bulk, compared to $3 to $5 for a single battery at a pharmacy. Shipping takes 2 to 7 days depending on your location and the seller's speed. Prime members on Amazon receive faster delivery, sometimes within 2 days.
When ordering online, check the seller's rating and the expiration date listed in the product details. Some sellers stock old inventory. Read the reviews — if multiple buyers report dead batteries or short shelf life, choose a different seller. Buying from the retailer's official store (Amazon's own inventory, for example) is usually safer than third-party sellers, though prices may be slightly higher.
Understand the difference between LR44, AG13, and SR44 before you buy
LR44, AG13, and SR44 are all small coin-cell batteries, but they have different chemistries and voltages. LR44 is alkaline, AG13 is also alkaline (and often interchangeable with LR44), and SR44 is silver oxide and lasts longer but costs more. Some devices work with any of these; others require a specific type. Check your device's manual or the battery compartment label before you order.
If you substitute the wrong type, the device may not work, work poorly, or drain the battery faster than expected. When in doubt, order the exact type listed in your manual. If you cannot find the manual, search the device model number plus "battery type" online, or ask the retailer's staff.
Frequently Asked Questions
Can I use an AG13 battery instead of an LR44?
AG13 and LR44 are both alkaline and have the same voltage, so they are usually interchangeable. However, check your device manual to be sure. Some devices are sensitive to battery chemistry and may not work reliably with a substitute. When in doubt, use the exact type your manual specifies.
How long does an LR44 battery last?
An LR44 battery lasts anywhere from a few months to two years depending on the device and how often it is used. Watches and calculators that draw minimal power last longer than hearing aids or toys with motors. Once installed, you will know when it is dead — the device will stop working or display a low-battery warning.
Is it cheaper to buy LR44 batteries online or in a store?
Online is cheaper per battery if you buy in bulk, often by 50 to 80 percent. A pack of ten from Amazon or eBay costs less per unit than a single battery at a pharmacy. However, you must wait for shipping. If you need a battery today, a drugstore is your only option, and the higher price is the cost of convenience.
Where do I dispose of used LR44 batteries?
LR44 batteries contain chemicals and should not go in household trash. Most drugstores and electronics retailers accept used batteries for recycling at the customer service desk or near the entrance. Some communities have battery recycling drop-off locations — search your city name plus "battery recycling" to find the nearest one.
Do LR44 batteries expire?
LR44 batteries have an expiration date, usually printed on the package. They lose charge slowly over time, even when not in use. Batteries within a year or two of the expiration date work fine. Batteries well past the date may be dead or weak. Always check the date before you buy, especially from clearance bins or old stock.
