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 any pharmacy with a health and beauty section, any grocery store with a battery aisle, and any electronics or office supply store. Online, Amazon, eBay, and the websites of major retailers all stock them. The battery itself is identical no matter where you buy it — the difference is price, quantity, and how fast you need it.
A single LR44 costs between 50 cents and $2 depending on the brand and where you shop. Buying a pack of four or eight is cheaper per battery than buying one. If you need a battery today, a local drugstore or supermarket is your fastest option. If you can wait a few days, online ordering is usually cheaper.
Key Takeaways
- Drugstores, supermarkets, and electronics retailers all carry LR44 batteries in their battery aisles or checkout areas.
- A single LR44 typically costs 50 cents to $2, but buying in packs of four or eight lowers the per-battery price.
- Local stores let you buy one battery today; online retailers offer better prices if you can wait a few days for delivery.
- LR44, SR44, and AG13 are the same battery under different brand names and will work in any device that calls for one of them.
- Counterfeit batteries are common on third-party marketplace listings, so buying from the retailer's own website or a pharmacy is safer than buying from an unknown seller.
Drugstores and supermarkets with battery aisles
Walgreens, CVS, Rite Aid, and most local pharmacies stock LR44 batteries in the health and beauty section or near the checkout counter. Supermarkets like Walmart, Target, Kroger, and Safeway carry them in the battery aisle, usually near AA and AAA batteries. You can walk in, find the battery section, and buy one or a pack without ordering ahead. Prices at these stores are higher than online, but you get the battery when ready.
Call ahead if you want to be sure the store has them in stock. Most pharmacies and supermarkets do, but smaller locations sometimes run out. Ask for "LR44" or "button cell batteries" — staff will know what you mean.
Electronics and office supply stores
Best Buy, Micro Center, Staples, and Office Depot all carry LR44 batteries. Best Buy stocks them in the accessories section near watch batteries and hearing aid supplies. Staples and Office Depot have them in the office supplies aisle. These stores often have multiple brands and pack sizes in stock, so you have more choice than at a pharmacy.
Prices at these retailers are similar to drugstores — higher than online, but you leave with the battery the same day. Some locations offer in-store pickup if you order online, which can be faster than waiting for shipping.
Online retailers and what to watch for
Amazon, eBay, Walmart.com, Target.com, and the websites of drugstores all sell LR44 batteries. Prices are usually 30 to 50 percent lower than in-store, especially if you buy a pack. Shipping typically takes three to seven days, depending on your location and whether you have a membership like Prime.
Be cautious of third-party sellers on Amazon and eBay, especially if the price seems very low. Counterfeit button-cell batteries are common on marketplace listings. Buy from the retailer's own website (Amazon.com directly, not a third-party seller; Walmart.com, Target.com) or from a pharmacy website to avoid fakes. Check the seller name before you buy — if it is not the retailer itself, scroll down and read reviews from other buyers first.
Understanding LR44, SR44, and AG13 labeling
LR44, SR44, and AG13 are the same battery. Different manufacturers use different names for the identical product. An LR44 made by Energizer works in any device that calls for an SR44 or AG13. The letters refer to the chemistry and size, not the brand. If your device manual says it needs an SR44 or AG13, you can safely buy an LR44 instead — it is the same thing.
Some sellers list these names separately to make it look like they have more products than they do. Do not buy three different listings thinking you are getting three different batteries. Check the specifications: if the voltage is 1.5V and the diameter is 11.6mm, it is the same battery regardless of what name is printed on the package.
Comparing prices and pack sizes
A single LR44 at a drugstore costs $1 to $2. A pack of four at the same store costs $3 to $5 (75 cents to $1.25 per battery). Online, a pack of eight costs $4 to $8 (50 cents to $1 per battery). If you use button-cell batteries regularly — for watches, hearing aids, or calculators — buying a pack online is the cheapest option. If you need one battery right now, a local store is worth the extra cost.
Store brands (Walgreens, Target, Walmart) are the same quality as name brands like Energizer or Duracell and cost less. Buy the store brand unless you have a reason to prefer a specific brand.
Hearing aid and medical supply stores
If you use LR44 batteries in a hearing aid, some hearing aid dispensers and medical supply stores sell them. Prices are usually higher than retail, but if you are already there for a hearing aid fitting or repair, it is convenient. Some hearing aid offices give batteries to patients for free or at a discount, so ask when you visit.
For regular use, a pharmacy or online retailer is cheaper. Medical supply stores are useful only if you are already there or if you need a specific brand your audiologist recommends.
Frequently Asked Questions
Can I use a rechargeable LR44 battery instead of a disposable one?
Rechargeable button-cell batteries exist, but they have a lower voltage (1.2V instead of 1.5V) and may not work in devices designed for disposable LR44s. Check your device manual before buying a rechargeable. Some devices work fine with the lower voltage; others will not turn on or will run dimly. If the manual does not say, test one in a non-critical device first.
How long does an LR44 battery last?
It depends on the device. In a watch, an LR44 lasts one to three years. In a hearing aid, it lasts three to seven days. In a calculator used occasionally, it can last several years. Check your device manual for the expected battery life, or replace the battery when the device stops working or dims.
Is there a difference between Energizer and Duracell LR44 batteries?
Both are reliable brands and perform similarly in most devices. Duracell batteries sometimes last slightly longer in high-drain devices like hearing aids, but the difference is small. Store brands work just as well for most uses and cost less. Buy whichever is in stock and in your budget.
What should I do with old LR44 batteries?
LR44 batteries contain mercury or other metals and should not go in the trash. Most drugstores and electronics retailers have battery recycling bins near the checkout or customer service desk. Some municipalities have hazardous waste collection days. Call your local waste management office or search online for "battery recycling near me" to find a drop-off location.
Can I buy LR44 batteries in bulk for a business or organization?
Yes. Wholesale retailers like Costco and Sam's Club sell LR44 batteries in large packs at lower per-unit prices. Office supply stores like Staples and Office Depot offer bulk discounts for business accounts. Contact their business sales department for pricing on orders of 50 or more units.
