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, toys, and small electronics. You can find them at pharmacies like CVS and Walgreens, grocery stores like Target and Walmart, electronics chains like Best Buy, and online at Amazon and eBay. Prices vary by brand and quantity — a single battery costs between $1 and $3, while multipacks of 4 to 10 batteries run $4 to $12. The battery is also called an A76, AG13, or 357 battery, depending on the manufacturer.
The most common places to look are the pharmacy aisle, the electronics section, or near the checkout counter. If you cannot find LR44 batteries in one location, try another aisle or ask a store employee — most retailers stock them but do not always display them prominently.
Key Takeaways
- Drugstores and supermarkets stock LR44 batteries in the pharmacy or electronics aisle, usually near checkout or in the watch section.
- Online retailers like Amazon, Walmart.com, and eBay often have lower per-unit prices when you buy multipacks, though you pay for shipping unless you have a membership.
- Brand matters less than freshness — check the expiration date on the package, especially if buying from clearance bins or older stock.
- Hearing aid retailers and watch repair shops carry LR44 batteries and can install them for you if you do not want to open the device yourself.
Drugstores and supermarkets carry LR44 batteries year-round
CVS, Walgreens, Rite Aid, and similar drugstores stock LR44 batteries in the pharmacy section or near the checkout counter. Walmart, Target, and grocery chains like Kroger and Safeway keep them in the electronics or battery aisle. These retailers usually have multiple brands in stock — Energizer, Duracell, Panasonic, and house brands are common. A single battery costs $1.50 to $3 depending on the brand and store.
The advantage of buying in-store is that you can check the expiration date before purchase and leave with the battery the same day. The disadvantage is that single-battery prices are higher than online multipacks. If you need only one battery for a watch or hearing aid, a drugstore is the fastest option. Most stores restock these batteries weekly, so availability is rarely a problem.
Online retailers offer lower prices per battery when you buy in bulk
Amazon, Walmart.com, Target.com, and eBay all sell LR44 batteries in multipacks of 4, 6, 8, or 10. A 10-pack on Amazon typically costs $5 to $8, which works out to 50 cents to 80 cents per battery — roughly half the in-store single-battery price. Shipping is free on Amazon Prime orders and on Walmart orders over $35. eBay sellers vary widely in price and shipping cost, so compare the total delivered price before buying.
The trade-off is that you must wait for delivery, usually 2 to 7 days depending on your location and the seller. If you need a battery today, online ordering does not help. If you use LR44 batteries regularly — for a hearing aid, for example — buying a multipack online and keeping spares on hand is more economical than buying single batteries at a drugstore over time.
Hearing aid retailers and watch repair shops stock LR44 batteries
If you wear a hearing aid, your audiologist or hearing aid dispenser stocks LR44 batteries and often sells them at a lower per-unit price than drugstores, especially if you buy a box of 10 or more. Many dispensers will install the battery in your hearing aid for you at no extra charge. This is useful if you have difficulty opening the battery door yourself or if you want to avoid handling the battery.
Watch repair shops and jewelry stores that service watches also carry LR44 batteries and can replace them while you wait. The price is usually $2 to $4 per battery, plus a small installation fee if you do not want to do it yourself. This option is worth considering if you already need watch repair or if you prefer having someone else handle the installation.
Check the expiration date and store batteries in a cool, dry place
LR44 batteries have a shelf life of 3 to 5 years from the manufacture date. When you buy, check the expiration date printed on the package — especially important if you are buying from a clearance bin or an older stock. A battery that expires in 6 months will lose charge faster than one that expires in 3 years.
Store unused batteries in a cool, dry place away from metal objects that could short-circuit them. A drawer or cabinet at room temperature is fine. Do not store them in a hot car, a humid bathroom, or near a heat source. If you buy a multipack and use only one or two, the rest will stay fresh longer if stored properly and kept in their original packaging.
LR44, A76, AG13, and 357 are the same battery with different names
Manufacturers label this battery differently depending on the brand. Energizer calls it an A76. Duracell calls it a 357. Panasonic and other brands call it an AG13 or LR44. They are all the same size and voltage — 1.5 volts, 11.6 millimeters in diameter, 5.4 millimeters thick. When you search online or ask a retailer, you can use any of these names and get the same battery.
If you are not sure which name your device uses, check the battery compartment or the device manual. Most watches, calculators, and hearing aids print the battery type on the inside of the battery door or in the instruction booklet. Knowing the exact name saves time when searching online or asking a store employee for help locating the battery.
Frequently Asked Questions
Can I use a different battery if I cannot find an LR44?
Not safely. LR44 is 1.5 volts. Some similar-looking batteries like SR44 are 1.55 volts and may damage sensitive electronics like hearing aids. Always use the exact battery type your device specifies. If you cannot find an LR44 locally, order online rather than substituting.
How long does an LR44 battery last in a hearing aid?
In a hearing aid, an LR44 battery typically lasts 3 to 7 days depending on how many hours per day you wear the aid and the power level of your device. In a watch, the same battery lasts 2 to 3 years because a watch uses far less power. Check your device manual for the expected battery life for your specific model.
Is it cheaper to buy LR44 batteries online or in a store?
Online multipacks are cheaper per battery — usually 50 cents to $1 each versus $1.50 to $3 in a store. But you pay for shipping unless you have free shipping through a membership or a minimum order. If you need one battery today, a drugstore is faster and the total cost is lower. If you use them regularly, buy a 10-pack online.
Do LR44 batteries expire?
Yes. LR44 batteries have a shelf life of 3 to 5 years from manufacture. Check the expiration date on the package before buying. A battery that is close to expiration will lose charge faster once installed in your device.
