Hearing Aid Battery Color Codes: Which Size is Yours?
Hearing aid battery color codes indicate battery size: yellow for size 10, brown for 312, orange for 13, and blue for 675.
Your hearing aid model determines which battery size you need, and the color-coded tabs make it easy to grab the right ones at the store.
Ever stood in the pharmacy aisle staring at tiny hearing aid batteries, wondering which ones fit your device? You’re not alone. I found that millions of people with hearing aids face this same puzzle every few weeks when their batteries die.
The good news? Once you know your color code, shopping becomes simple. Let me walk you through everything you need to know about hearing aid battery sizes and their colors.
The Four Main Hearing Aid Battery Sizes and Colors
There are four standard hearing aid battery sizes used worldwide. Each has its own color code that stays the same across all brands.
Size 10 Batteries (Yellow)
Size 10 batteries wear yellow tabs. These are the smallest hearing aid batteries available.
You’ll find them in:
- Completely-in-canal (CIC) hearing aids
- Invisible-in-canal (IIC) devices
- Some small in-the-ear models
These tiny powerhouses last about 3-5 days. Their small size means less power storage, but they fit in the most discreet hearing aids.
Size 312 Batteries (Brown)
Brown tabs mark size 312 batteries. These are probably the most common batteries you’ll see.
They power:
- Mini behind-the-ear (BTE) hearing aids
- Receiver-in-canal (RIC) devices
- Some in-the-ear hearing aids
Size 312 batteries typically last 7-10 days. They offer a good balance between size and power life.
Size 13 Batteries (Orange)
Orange tabs identify size 13 batteries. These medium-sized batteries are workhorses.
You’ll use them in:
- Behind-the-ear hearing aids
- Some in-the-ear models
- Hearing aids with extra features like Bluetooth
These batteries last about 10-14 days. They provide more power for hearing aids with advanced features.
Size 675 Batteries (Blue)
Blue tabs mark the largest hearing aid batteries – size 675. These are the marathon runners of hearing aid power.
They’re used in:
- High-power behind-the-ear hearing aids
- Severe to profound hearing loss devices
- Cochlear implant processors
Size 675 batteries can last 15-20 days. Their extra size means extra power for demanding devices.
Quick Reference Table

| 675 | Blue | 15-20 days | High-power devices |
How to Find Your Battery Size
Not sure which size you need? Here are three easy ways to find out.
Check Your Current Battery
Look at the battery in your hearing aid right now. The color of the tab tells you everything. Remove it carefully and check the color before throwing it away.
Look at Your Hearing Aid Manual
Your hearing aid came with paperwork that lists the battery size. If you can’t find the manual, search online for your hearing aid model number plus “battery size.”
Ask Your Audiologist
Your hearing care professional knows exactly which batteries you need. They can also show you how to change them properly.
Check the Hearing Aid Itself
Some hearing aids have the battery size printed on the device. Look for tiny numbers near the battery door.
Why Color Codes Matter
You might wonder why we need color codes at all. Can’t you just read the numbers?
Here’s the thing: hearing aid batteries are tiny. The numbers printed on them are often hard to read, especially if your vision isn’t perfect.
Colors are much easier to spot. Even in dim store lighting, you can quickly identify the right battery pack. It’s like having a built-in shopping guide.
Battery Life Factors
The life spans I mentioned are averages. Your actual battery life depends on several things.
Your Hearing Loss Level
More severe hearing loss means your hearing aid works harder. Working harder drains batteries faster.
Environmental Conditions
Hot and cold temperatures affect battery life. Very humid conditions can also shorten battery life.
Hearing Aid Features
Bluetooth streaming, noise reduction, and feedback cancellation all use extra power. More features mean shorter battery life.
How Often You Use Your Hearing Aids
Wearing your hearing aids 16 hours a day drains batteries faster than wearing them 8 hours a day. Makes sense, right?
Battery Freshness
Zinc-air batteries start dying the moment you remove the tab. Fresh batteries always last longer than ones that sat around for weeks.
Tips for Better Battery Life
Want to squeeze more life from your batteries? Try these simple tricks.
Store Batteries Properly
Keep batteries in a cool, dry place. Room temperature works great. Don’t store them in the refrigerator – that can cause condensation problems.
Wait Before Using New Batteries
After removing the tab, wait 60 seconds before putting the battery in your hearing aid. This lets air activate the battery fully.
Open the Battery Door at Night
When you’re not wearing your hearing aids, open the battery door. This turns off the device and prevents battery drain.
Clean Your Battery Contacts
Dirty battery contacts waste power. Gently clean them with a dry cotton swab once a week.
Shopping for Batteries
Now that you know your color code, shopping becomes easy. But here are some extra tips.
Buy from Busy Stores
Stores with high turnover sell fresher batteries. Fresh batteries last longer than ones that sat on shelves for months.
Check Expiration Dates
Hearing aid batteries typically last 3-4 years unopened. Always check the expiration date before buying.
Buy the Right Quantity
Don’t buy a year’s supply at once. Batteries slowly lose power even when unopened. Buy what you’ll use in 2-3 months.
Consider Online Shopping
Online retailers often have competitive prices and fresh inventory. Just make sure they’re reputable sellers.
Common Battery Mistakes
I’ve found that people make the same battery mistakes over and over. Let me help you avoid them.
Removing the Tab Too Early
Once you remove that colored tab, the battery starts working. Don’t remove it until you’re ready to use the battery.
Touching the Battery Surfaces
Oil from your fingers can interfere with battery contacts. Handle batteries by the edges when possible.
Ignoring Low Battery Warnings
Modern hearing aids beep when batteries get low. Don’t ignore these warnings. Change the battery promptly to avoid sudden shutdowns.
Mixing Battery Types
Stick with one brand when possible. Mixing different battery types can cause performance issues.
What About Rechargeable Options?
Many newer hearing aids use rechargeable batteries instead of disposable ones. These devices typically charge overnight in a small case.
Rechargeable hearing aids don’t use the color-coded battery system. They have built-in lithium-ion batteries that last 3-5 years.
If you have rechargeable hearing aids, you don’t need to worry about battery colors or sizes. Lucky you!
Emergency Battery Situations
What happens when your battery dies and you don’t have a replacement?
Pharmacy and Drug Stores
Most pharmacies carry hearing aid batteries. Look for them near the pharmacy counter or in the health section.
Grocery Stores
Many grocery stores stock basic hearing aid battery sizes. They’re usually near the regular batteries or in the pharmacy area.
Hearing Aid Centers
Audiologist offices almost always have batteries available. Some sell them even if you’re not a patient.
Conclusion
Remember your color code, and hearing aid battery shopping becomes simple. Yellow for size 10, brown for 312, orange for 13, and blue for 675. Write it down, save it in your phone, or just remember that the smaller the hearing aid, the smaller (and more yellow) the battery tends to be.
Taking care of your batteries properly helps them last longer and keeps your hearing aids working at their best. Store them right, change them when needed, and don’t be afraid to ask for help if you’re unsure about anything.
Your hearing is worth the small effort it takes to keep fresh batteries in your devices. Now you have the knowledge to keep the power flowing.
What happens if I use the wrong size battery in my hearing aid?
Wrong size batteries simply won’t fit properly in your hearing aid. The battery door won’t close correctly, and your device won’t work. There’s no risk of damage, but you’ll need to get the correct size to restore function.
Can I use rechargeable versions of zinc-air batteries?
Rechargeable zinc-air batteries exist but aren’t recommended for hearing aids. They provide less power and shorter life than regular disposable batteries. Stick with standard zinc-air batteries unless your hearing aid is specifically designed for rechargeables.
How should I dispose of used hearing aid batteries?
Many hearing aid centers, pharmacies, and electronics stores accept used hearing aid batteries for recycling. Don’t throw them in regular trash as they contain zinc and other materials that can be recycled safely.
Do generic hearing aid batteries work as well as name brands?
Quality generic batteries often perform just as well as name brands. Look for batteries made by reputable manufacturers and check customer reviews. The most important factors are freshness and proper storage, not necessarily the brand name.
Why do my batteries die faster in winter than summer?
Cold temperatures slow down the chemical reactions inside zinc-air batteries, reducing their effective life. Additionally, heating systems create drier air, which can affect how the batteries interact with moisture from the air they need to function.
