Hearing aid batteries seem like a small detail until you’re halfway through a long day and the sound cuts out mid-conversation. Size 675 cells sit inside many of the most common behind-the-ear and cochlear implant devices, and the difference between a sluggish zinc-air cell and a steady one shows up in everything from phone calls to dinner table conversations. This roundup covers eight solid options worth knowing about, whether you’re buying in bulk for a household or stocking a single pair.

More On The Choices That Made The List
Size 675 cells are the workhorses behind many modern hearing aids and cochlear implants, and this PHILIPS pack lands at the top of the list for good reason. A 60-count card covers roughly two to three months for most daily wearers, which means fewer last-minute pharmacy runs when a battery dies during a work call.
The zinc-air chemistry inside delivers a steady 1.45V output, the standard voltage hearing aids expect. That consistency matters more than people realize: a stable supply keeps the amplifier from distorting at high volumes and prevents the frustrating mid-conversation dropouts that plague cheaper cells.
Features That Help
- Tab pull-strip design makes single-cell removal quick, even with limited hand strength
- Mercury-free zinc-air construction, the current industry standard for safe disposal
- Bulk 60-count format keeps a household stocked for an entire quarter
- Compatible cross-reference codes A675, ZA675, and PR44 cover most major hearing aid brands
Points To Note
- Once the tab is removed, the battery starts draining, so only peel what you’ll install soon
- Storage in humid bathrooms can shorten shelf life noticeably
- Newer listing means less long-term owner feedback compared to legacy brands
Key Product Details
Who It Suits Best
Daily hearing aid wearers who go through a size 675 cell every few days and want to buy in bulk without locking into a single-use pharmacy pack.
A Better Fit Elsewhere
If you rely on a cochlear implant rather than a standard hearing aid, the Power One Cochlear Implant Batteries on this list are tuned specifically for that workload.
Size 312 cells live inside smaller in-ear hearing aids, where every fraction of a millimeter matters. This PHILIPS 24-pack hits a sweet spot for first-time wearers who want a manageable starter stash without committing to a 60-count tower.
The same 1.45V zinc-air platform runs here, so users moving from a 675 device will find the install process familiar. Cross-reference codes A312, ZA312, and PR41 confirm compatibility with the leading receiver-in-canal brands currently shipping.
Useful Highlights
- Smaller cell fits RIC and CIC-style hearing aids comfortably
- Lower per-pack commitment reduces waste for occasional wearers
- Pull-tab design matches the size 675 cells above, simplifying routines across devices
Honest Caveats
- Smaller battery means shorter runtime per cell than size 675
- 24-count may run out quickly for full-time wearers
- Same new-listing caveat as the larger PHILIPS size, so long-term reliability data is limited
Right Fit For
People with smaller hearing aids who wear them intermittently and prefer a smaller backup pack rather than a storage-room-sized tower.
Skip It When
You wear a heavy-duty behind-the-ear device; the PHILIPS Size 675 60-Count is sized for that workload instead.
ZeniPower has been around long enough that you’ll find packs stashed in audiologist offices across the country. This listing pairs 60 size 675 cells with a small keychain holder, which addresses one of the most common frustrations: getting caught without a spare when a battery dies unexpectedly.
The zinc-air chemistry inside is well documented, with manufacturers citing strong energy density and a sealed shelf life measured in years rather than months. For commuters and travelers, that keychain holder often makes the difference between a smooth day and an emergency pharmacy stop.
Notable Gains
- Included keychain holder keeps spare cells accessible on the go
- Long-established brand with broad audiologist familiarity
- Flat discharge curve helps hearing aids perform consistently as the cell drains
- Bulk 60-cell pack suits households with multiple wearers
Things To Consider
- Keychain holder may not fit larger tabs or specialty cells
- Stock-keeping units vary widely; verify pack count at checkout
- Cells perform best when stored at room temperature, away from car gloveboxes
Quick Facts
Who Will Love This
Frequent travelers and commuters who want spares reachable without digging through a bag or glove compartment.
Consider Something Else When
You need maximum runtime from a single cell; the VARTA Power One on this list carries a documented higher capacity rating that suits heavier draws.
Duracell is one of the names that comes up first in any battery aisle, and the hearing aid line carries the same color-coding and reliability reputation. The blue tab on a size 675 is the universal signal for this cell type, so swapping between brands without confusion is easy.
The standout feature here is the extra-long EasyTab, which the Arthritis Foundation has recognized as easier to handle for people with limited dexterity. For anyone with arthritis, tremors, or reduced grip strength, that small change in tab length saves real frustration during the morning swap.
Practical Advantages
- Long pull-tab simplifies removal, especially for arthritic hands
- Blue color-coding matches the standard size 675 convention
- Compact 12-pack fits easily in a purse or travel kit
- Trusted brand widely stocked across drugstores
Worth Noting
- Smaller pack means more frequent reordering
- Per-cell price typically runs higher than bulk options
- Performance depends on seal freshness, so check manufacturing date on arrival

Another Choice May Suit
If your hands are steady and you burn through cells weekly, the PHILIPS Size 675 60-Count delivers a much better per-cell value.
Cochlear implants draw noticeably more current than standard hearing aids, and not every size 675 cell is engineered for that load. Power One (now sold under the VARTA umbrella) built its reputation on heavy-drain performance, and Cochlear Corporation has recommended the brand specifically for its processors.
The 60-count across ten individual cards is a useful format for implant users who rotate between processors or want to spread supplies across locations like home, work, and a travel bag.
Useful Strengths
- Recommended by Cochlear Corporation for its sound processors
- Multiple smaller cards improve portability versus one large brick
- Engineered for the high current draw typical of implant devices
- Established track record in the audiology community
Trade Offs
- Per-cell cost sits higher than general-purpose size 675 cells
- May be overkill for users with standard BTE hearing aids
- Ten-card packaging creates more plastic waste than single-pack options
Who Should Grab It
Cochlear implant users who need cells engineered for sustained high current draw and value brand approval from their device manufacturer.
Look Elsewhere When
You wear a standard hearing aid rather than an implant, in which case the VARTA Power One Size 675 Pack of 60 offers similar chemistry at a friendlier entry point.
VARTA owns the Power One brand, and this listing carries the full technical data sheet, which is rare among hearing aid battery listings. The 1.45V output pairs with a documented 650 mAh typical capacity, giving users a real number to compare against rather than vague “long-lasting” language.
The cell dimensions and weight (11.6mm diameter, 5.4mm height, 1.85g) confirm it matches the IEC PR44 standard, which means drop-in replacement across major hearing aid brands without fitment concerns.
What Pays Off
- Documented 650 mAh capacity gives realistic runtime expectations
- Verified cell dimensions confirm standard PR44 fit
- Strong zinc-air discharge curve suited to streaming and Bluetooth use
- 60-count pack suits high-consumption users and shared households
Some Limits To Know
- Listing may be older inventory, so verify freshness at delivery
- Premium capacity often carries a higher per-cell price
- Same chemistry means storage conditions matter as much as brand
The Numbers That Matter
Built With In Mind
Users who stream audio or take frequent Bluetooth calls and need cells that hold up under sustained current draw without voltage drop.
Reach For A Different Pick When
Budget matters more than capacity; the PHILIPS Size 675 60-Count delivers similar 1.45V output at a more accessible per-cell rate.
Size 13 is the orange-tab sibling many behind-the-ear wearers rely on daily. This PHILIPS pack rounds out the same product family reviewed above, so anyone running multiple hearing aid sizes in one household can standardize on a single trusted brand.
The 1.45V output and zinc-air chemistry match the size 675 cells, making the swap between devices feel seamless. Cross-reference codes A13, ZA13, and PR48 cover the major manufacturers without compatibility questions.
The Upside
- Brand consistency for households using multiple hearing aid sizes
- Pull-tab design mirrors the size 675 format for predictable handling
- Bulk 60-count covers a full quarter for typical wear patterns
Where It May Fall Short
- Orange color-coding is easy to confuse with other sizes in dim lighting
- Newer listing means less long-term community feedback to lean into
Whose Shelf It Belongs On
Behind-the-ear wearers using size 13 cells who already trust the PHILIPS line and want bulk supply at a steady per-cell rate.
Where A Sibling Pick Shines
For pure size 675 focus, the PHILIPS Size 675 60-Count is the more direct fit and avoids any cross-size confusion.
Size 10 cells are the smallest of the standard hearing aid battery family, often hidden inside completely-in-canal devices where visibility isn’t an option. The yellow tab signals the size in any lighting, which helps when fumbling for a swap in a dim hotel room.
This pack closes out the PHILIPS family covered earlier, giving a single-source solution for households with size 10, 13, and 675 devices. Cross-references A10, ZA10, and PR70 confirm broad brand compatibility.
Notable Upsides
- Compact cell fits the smallest in-canal hearing aids
- Yellow color tab matches the universal size 10 standard
- Same 1.45V zinc-air chemistry as the larger sizes for predictable behavior
A Few Limitations
- Smaller cell means shortest runtime of the standard sizes
- Bulk 60-count may sit unused for occasional wearers
- Tab is shorter than the Duracell EasyTab, so handling is less forgiving
Made For
Wearers of miniature in-canal hearing aids who need the smallest cell size and value brand consistency across their household.
Swap It Out When
You rely on a larger device; the PHILIPS Size 675 or Size 13 packs above will give you fewer swaps per month.
What Matters Most Before Choosing 675 Hearing Aid Batteries
Confirming The Right Cell Size
Size 675, 312, 13, and 10 all look similar in passing, but they’re not interchangeable. The color tab on the packaging (blue, brown, orange, yellow) and the cross-reference codes printed on the back of your hearing aid manual are the safest ways to verify. Buying the wrong size means a cell that simply won’t fit in the compartment.
Matching Chemistry To Your Hearing Aid
Zinc-air batteries (the dominant chemistry in this list) need air exposure to activate, which is why they ship with a sealing tab. Once removed, the cell is slowly draining, even when sitting on a counter. A hearing aid that draws heavy current from streaming or Bluetooth benefits from documented high-capacity cells like the VARTA Power One, while a basic BTE device runs fine on standard zinc-air chemistry.
Pack Format And Storage Conditions
Bulk 60-count packs deliver better per-cell value but only make sense if you go through cells quickly. Storage matters: heat, humidity, and car gloveboxes all shorten shelf life. Room-temperature drawers and the original sealed packaging keep cells ready when you need them.
Dexterity And Handling
Anyone with arthritis or tremor will notice the difference between a short tab and a long EasyTab. The Duracell 12-pack exists largely to address this pain point, but several other listings also feature lengthened pull tabs. Test the tab length against your grip comfort before committing to a bulk purchase.
Key Considerations Across These Picks
Where Shoppers Go Wrong
The most common mistake is assuming all size 675 cells are the same. Cells with sealed tabs that have been sitting in a hot warehouse for months lose capacity long before the expiration date, so freshness matters more than brand recognition. Another trap is buying 60-cell packs without confirming the size code; “675” gets misread as “675 mAh” or “675 type,” neither of which exists as a meaningful spec.
What Separates Premium From Basic
Higher-tier cells earn their position with documented capacity ratings, tighter voltage consistency, and stronger seals that resist humidity. For users streaming audio all day or running cochlear implants, that consistency translates to fewer mid-day dropouts and steadier amplification. Casual wearers may not notice the difference, but heavy users quickly learn to recognize it.
Frequently Asked Questions
How long does a size 675 hearing aid battery actually last?
A size 675 cell typically runs five to seven days under standard daily use, though heavy Bluetooth streaming can drop that to three or four days. Higher-capacity cells like the VARTA Power One often stretch toward the upper end of that range.
Are all size 675 batteries interchangeable between brands?
Yes, as long as the cell meets the IEC PR44 standard, which all major brands including PHILIPS, Duracell, Power One, and ZeniPower follow. Cross-reference codes A675, ZA675, and PR44 all refer to the same physical size.
Why do these batteries have a tab on them?
The tab seals tiny air holes on the cell until use. Zinc-air chemistry needs oxygen to activate, so the tab keeps the battery dormant on the shelf. Once peeled, the cell begins discharging whether or not it’s installed in a device.
Can I store unused 675 batteries in the bathroom?
No, humidity is the enemy of zinc-air cells. A cool, dry drawer at room temperature preserves shelf life much better than a bathroom medicine cabinet. Keep spare cells in their original packaging until you need them.
Is there a difference between hearing aid batteries and watch batteries?
Yes, despite similar button-cell appearances, hearing aid batteries are specifically zinc-air and designed for the steady voltage curves hearing aids require. Watch batteries are typically silver-oxide and can damage hearing aid electronics if substituted.
Closing Thoughts
The right size 675 hearing aid battery comes down to matching cell chemistry, capacity, and pack format to your daily routine. Heavy streamers and cochlear users get the most from documented high-capacity cells, while casual wearers benefit more from bulk value and easy-to-handle tabs. Whichever pick matches your situation, keeping a sealed spare within reach is the simplest insurance against an unexpected mid-day silence.
