Another reason I prefer Costco is the convenience. Buying hearing aid batteries there saves me time and effort, as they often come in bulk at a great price.

My Buying Guides on Hearing Aid Batteries Costco
When I first needed hearing aid batteries, Costco was one of the first places I checked. Over time, I’ve learned a few key things about buying hearing aid batteries there that I want to share with you. Here’s my experience and tips to help you make the best choice.
Why I Choose Costco for Hearing Aid Batteries
Costco offers a great balance of price, quality, and convenience. I found their batteries to be reliable and often priced lower than other retailers. Plus, if you’re already a Costco member, it’s easy to pick them up during your regular shopping trips or order online.
Types of Hearing Aid Batteries Available at Costco
From my experience, Costco stocks the most common hearing aid battery sizes:
- Size 10 (yellow)
- Size 13 (orange)
- Size 312 (brown)
- Size 675 (blue)
These sizes cover the majority of hearing aids on the market, so you’ll likely find what you need. I always check my hearing aid manual or the battery packaging to confirm the correct size before buying.
Cost and Value
One thing I appreciate about buying at Costco is the cost savings. Hearing aid batteries can get pricey, but Costco often sells them in bulk packs, which lowers the cost per battery significantly. I usually compare the price per battery to other stores and online options, and Costco generally comes out ahead.
Battery Shelf Life and Quality
I’ve learned that freshness matters with hearing aid batteries. Costco’s batteries generally have a good shelf life, often lasting several years unopened. I always check the expiration date on the package before purchasing to make sure I’m getting the freshest stock available.
Buying In-Store vs. Online at Costco
Depending on my schedule, I either buy batteries in person or online. In-store buying lets me get the batteries immediately, which is handy if I’m running low. Online ordering is convenient and sometimes offers larger pack sizes or special deals. Costco’s website also provides customer reviews, which I find helpful.
Additional Tips from My Experience
- Store batteries properly: Keep them in a cool, dry place until use.
- Activate batteries correctly: Peel off the tab and wait about a minute before inserting to maximize performance.
- Keep spare batteries handy: I always buy extra so I’m never caught without power.
- Use Costco’s hearing aid center: If you have questions or need assistance, Costco’s hearing aid centers are very helpful.
Final Thoughts
Buying hearing aid batteries at Costco has worked well for me in terms of price, availability, and quality. If you’re a Costco member, it’s definitely worth considering as your go-to source. Just remember to check your battery size, expiration dates, and stock up wisely.
I hope my buying guide helps you find the right hearing aid batteries at Costco with ease!
