Costco’s batteries consistently provide that reliability, giving me peace of mind throughout the day without constant worry about my hearing aids dying at inconvenient times.
Another reason I prefer Costco is the convenience and value they bring. Buying batteries there means I get a good supply at a lower price compared to many other retailers.

My Buying Guides on Hearing Aid Batteries Costco
When I first started looking for hearing aid batteries at Costco, I realized there are a few key things to keep in mind to make the best choice. Here’s what I learned from my experience that might help you too.
Why Choose Hearing Aid Batteries from Costco?
Costco offers great value when it comes to hearing aid batteries. I found that their prices are often lower than other retailers, and you get good quality packs with multiple batteries. Plus, if you’re a Costco member, the convenience of buying in-store or online makes it easy to keep my hearing aids powered without hassle.
Types of Hearing Aid Batteries Available at Costco
Costco primarily stocks zinc-air batteries, which are standard for most hearing aids. The common sizes I encountered are:
- Size 10 (yellow)
- Size 312 (brown)
- Size 13 (orange)
- Size 675 (blue)
I recommend checking your hearing aid or the user manual to know which size you need before purchasing.
How to Identify the Right Battery Size
When I first bought batteries, I was a bit confused by the color codes and numbers. Here’s a simple tip: the battery size is usually printed on the hearing aid or in the packaging. Each size corresponds to a specific color tab, making it easier to pick the correct pack at Costco.
Battery Life and Storage Tips
From my experience, hearing aid batteries last around 3 to 10 days depending on usage and device type. To maximize battery life, I store them in a cool, dry place and only remove the tab right before use. Costco’s packaging usually comes with tabs intact, so keeping them sealed until needed helps maintain battery power.
Costco’s Return and Exchange Policy
I appreciated that Costco offers a satisfaction guarantee on their hearing aid batteries. If you find any defective batteries or if they don’t work well with your device, Costco’s customer-friendly return policy made it easy for me to exchange or get a refund.
Buying in Bulk vs. Smaller Packs
Costco sells hearing aid batteries in multi-packs, which is great if you use your hearing aids daily like I do. Buying in bulk saves money and reduces frequent trips to the store. However, if you don’t use your hearing aids often, smaller packs might be a better option to avoid batteries losing charge over time.
Final Thoughts
Overall, I found Costco to be a reliable and cost-effective source for hearing aid batteries. Just make sure to know your battery size, store them properly, and take advantage of Costco’s membership benefits for the best deals. With these tips, keeping your hearing aids powered up is much easier!
