If you’ve ever had a hearing aid die mid-conversation or right before an important call, you already know how much battery choice matters. The right cell keeps audio steady, the wrong one leaves you guessing. I pulled together six picks that cover the everyday bases, from disposable zinc-air cells to a rechargeable option for folks who want fewer swaps.
An Overview Of The Picks
A Closer Look At Each Pick
The size 675 cell is the workhorse behind many behind-the-ear (BTE) and high-power hearing aids, the kind used by people with more severe hearing loss who depend on stronger amplification. PHILIPS builds these as zinc-air units, the standard chemistry for hearing aids, where the cell is activated by air once the sticker tab is pulled off. That chemistry gives a flat voltage curve, which is what keeps sound from dipping in the middle of the day.
With a 60-count pack, most wearers can stretch supply across months without constant reordering. For anyone running a streaming-heavy device, the extra capacity translates directly into fewer mid-day changes. Compared with the smaller cells below, the 675 also tends to handle wireless streaming and Bluetooth drain a bit more gracefully.
Strengths Worth Knowing
- Steady 1.45V output across the cell’s life keeps audio levels consistent.
- Bulk 60-pack reduces reordering frequency for daily wearers.
- Designed for high-drain BTE and streaming use without sudden cutoffs.
- Easy-open tab design simplifies handling for users with limited dexterity.
Things To Consider
- Larger physical cell may not fit smaller in-canal style aids.
- Storage life on zinc-air is shorter than alkaline, so buy what you’ll use within a year or so.

Whose Drawer This Belongs In
Anyone running a powerful BTE hearing aid or a streaming-heavy device who wants fewer battery changes and steadier voltage through long days.
Reach For A Different Pick When
Wearers using tiny completely-in-canal aids should look at the PHILIPS Size 10 Hearing Aid Batteries 60 Count, which fits far smaller housings.
Size 312 is one of the most common cells in modern hearing aids, sitting in the sweet spot between the larger 675 and the smaller 10. Most receiver-in-canal (RIC) and slim BTE designs use it. PHILIPS markets this 24-pack as a stable zinc-air cell tuned for steady voltage output across its discharge cycle, which matters because hearing aids tend to behave more predictably when voltage doesn’t drift.
The 24-count format works well for people who want to rotate fresh stock without committing to a giant case. In most daily wear scenarios, this cell offers a noticeable step up in longevity over the size 10 while staying small enough for discreet devices. It’s a comfortable middle ground.
Where It Delivers
- Common 312 size fits most RIC and mini-BTE hearing aids.
- Consistent voltage reduces audio dips during calls and streaming.
- Smaller pack format keeps cells from aging out in storage.
- Pull-tab activation makes replacement quick and clean.
Worth Noting
- 24 cells run out faster than bulk packs for heavy daily users.
- Once the tab is pulled, the cell starts ticking, so install only when ready.
Right Fit For
RIC wearers and anyone using a moderate-drain hearing aid who prefers smaller, fresher batches over long-term storage.
Swap It Out When
Heavy users going through more than a cell every few days benefit more from the Rayovac Extra Advanced Size 312 Hearing Aid Batteries 60 Pack, which offers the same size in a larger bulk format.
Rayovac has been making hearing aid cells for a long time, and the Extra Advanced line is its high-capacity tier. The 312 size here matches what most RIC wearers already use, so this is essentially a bulk upgrade over the 24-pack option above. The brown color tab is the standard industry indicator for size 312, which helps avoid mix-ups in a drawer full of similar-looking cells.
For people who chew through cells quickly, whether due to heavy streaming, long days, or just two devices, a 60-count frustration-free pack keeps interruptions down. Rayovac also emphasizes high energy density, which in plain terms means more usable hours per cell. The mercury-free construction aligns with current environmental standards for hearing aid batteries.
What Pays Off
- Bulk 60-pack lowers per-cell cost for frequent swappers.
- Mercury-free chemistry meets modern environmental guidelines.
- Frustration-free packaging opens cleanly, helpful for arthritic hands.
- Stable energy output across the discharge cycle, based on Rayovac’s stated density claims.
Trade Offs
- Large pack takes longer to use up, so storage conditions matter.
- Brand tab color follows standard, but mixing cells in shared drawers can still cause confusion.
Built With In Mind
Daily RIC wearers who burn through size 312 cells regularly and prefer buying in bulk over monthly reorders.
Look Elsewhere When
Anyone using BTE or high-power aids should consider the PHILIPS Size 675 Hearing Aid Batteries 60 Count, which targets a more demanding cell class.
Size 13 sits between the common 312 and the larger 675 in both physical size and typical capacity. It’s a standard fit for many in-the-canal (ITC) hearing aids and some smaller BTE models. PHILIPS positions it as a steady 1.45V zinc-air cell aimed at avoiding the mid-day lag that can show up in cells with weaker voltage regulation.
The orange-tab color coding helps separate it from other sizes in a household drawer, a small thing that prevents real frustration. Compared with the 24-pack size 312 above, this 60-count offers more longevity per cell, depending on the specific aid. For wearers who already know they need a 13, this is the practical bulk option.
A Strong Showing
- Reliable voltage curve for ITC and standard BTE hearing aids.
- Bulk 60-pack supports heavy daily use.
- Standardized tab color prevents mix-ups in shared storage.
- Pull-tab design keeps the cell sealed until installation.
Soft Spots
- Not universal, so confirm your aid’s battery door label before buying in bulk.
- Zinc-air shelf life means very slow users may see cells expire before use.
Feature Rundown
Who Should Grab It
ITC wearers and anyone running BTE aids that specify a size 13 cell and prefers buying in multi-month bulk.
A Better Fit Elsewhere
Wearers using smaller, more discreet aids should turn to the PHILIPS Size 10 Hearing Aid Batteries 60 Count for the correct fit.
Size 10 is the smallest of the standard disposable hearing aid cells, and it’s the one that fits completely-in-canal (CIC) and invisible-in-canal aids. Tiny devices demand tiny power, and this cell delivers the right footprint while keeping the same 1.45V zinc-air chemistry that the larger sizes use. That consistency across sizes is genuinely useful, since voltage behavior stays familiar regardless of which cell your aid takes.
The 60-count gives CIC wearers enough supply to cover extended use, which matters because the small size means cells tend to drain faster relative to capacity. The yellow-tab color coding is the standard identifier for size 10 and helps avoid mix-ups with the 312 brown or 13 orange tabs in a shared drawer.
The Upside
- Smallest standard cell fits CIC and mini-CIC hearing aids.
- Same zinc-air platform as larger sizes for consistent behavior.
- Bulk format suits frequent cell changes in tiny devices.
- Easy-open packaging for users managing cells with reduced grip strength.
Points To Keep In Mind
- Capacity is lower than larger cells, so heavy stream users will swap more often.
- Very small cell can be tricky to handle for users with dexterity challenges.
Perfect Match For
CIC and IIC wearers who need the smallest standard cell and want to keep a multi-month supply on hand.
Consider Something Else When
Users with dexterity issues who find tiny cells frustrating may prefer the Karthus Rechargeable Hearing Aids for Seniors White, which eliminates cell swaps entirely.
This pick shifts gears entirely. Instead of disposable cells, the Karthus unit is a rechargeable hearing amplifier designed for adults with mild to moderate hearing loss. The big draw is the built-in 100-hour battery life, which removes the recurring cost and hassle of buying zinc-air cells. For seniors or first-time wearers, that’s often the difference between using hearing assistance consistently and forgetting about it.
The unit runs a 16-channel DSP (digital signal processor), which helps separate speech from background noise in everyday situations like TV watching and family dinners. Seven volume levels and a single-button operation keep the controls approachable. The behind-the-ear form factor stays discreet enough for daily wear without drawing attention.
Features That Help
- Rechargeable design eliminates ongoing battery purchases.
- Single-button operation simplifies use for those less comfortable with tech.
- 16-channel DSP targets speech clarity in common noisy settings.
- Seven volume levels allow fine-tuning without a smartphone app.
- Lightweight BTE form factor stays comfortable for long days.
Honest Caveats
- Intended for mild to moderate loss, not a substitute for clinically fitted aids in severe cases.
- Rechargeable built-in cell means the unit has a service life that disposables don’t.
Feature Overview
Made For
Seniors and first-time wearers with mild to moderate hearing loss who want simple controls and no battery swaps.
Where Another Pick Suits Better
Anyone already using a clinically fitted hearing aid should stick with disposable cells like the PHILIPS Size 13 Hearing Aid Batteries 60 Pack for ongoing replacements.
What To Weigh Before Choosing Battery Hearing Aids
The first decision is which cell size your hearing aid actually uses, since these are not interchangeable. Sizes 10, 13, 312, and 675 each match specific device categories, from completely-in-canal aids (size 10) to high-power behind-the-ear models (size 675). Check the battery door of your current aid or the user manual, because guessing leads to cells that simply don’t fit.
Chemistry matters more than brand for daily performance. Zinc-air cells, the standard across all the picks here, deliver a flat 1.45V output that keeps hearing aids sounding consistent from morning to evening. Once you pull the activation tab, the cell starts draining regardless of whether it’s installed, so replace the tab only when you’re ready.
Pack size affects value and freshness. Bulk packs like the 60-count Rayovac and PHILIPS options reduce per-cell cost but mean slower turnover. If you go through a cell every few days, bulk wins. Light users may see cells expire on the shelf, so smaller packs like the 24-count PHILIPS size 312 make more sense.
Rechargeable aids like the Karthus unit change the math entirely. There’s no recurring cell purchase, but the device has a finite service life tied to its built-in battery. For users with mild to moderate loss who want simplicity, that tradeoff often pays off. For heavier loss or specialized fittings, disposables still dominate.
Common Shopping Slip Ups
The most frequent mistake is buying the wrong cell size. A 312 won’t fit a device designed for a 13, and the color tab system only helps if you actually check it. Always confirm the size printed on your aid’s battery door before ordering in bulk.
Another trap is buying cheap no-name cells and expecting premium longevity. Established zinc-air cells from PHILIPS and Rayovac use consistent quality control, which translates to fewer dead-on-arrival cells and more predictable voltage curves. For daily-use hearing aids, that predictability matters more than saving a few cents per cell.
What The Higher Tier Buys
Premium-tier hearing aid cells focus on voltage stability and longevity under heavy drain. Features like the long-lasting discharge profiles in the PHILIPS 675 and Rayovac Extra Advanced lines translate to fewer mid-day cutoffs during streaming or phone calls. For users with high-drain BTE aids, that extra reliability justifies the modest cost step up over generic bulk options.
The rechargeable tier like the Karthus unit adds DSP processing, longer per-charge life, and simpler controls. The upgrade makes sense for users who prioritize convenience over clinical-grade customization, especially seniors managing mild to moderate loss without a complex fitting.
Frequently Asked Questions
How long does a hearing aid battery typically last? A size 312 or 13 zinc-air cell typically lasts 5 to 12 days with daily wear. Size 675 cells often run longer, while size 10 cells in tiny CIC aids usually drain fastest due to smaller capacity.
Are all hearing aid batteries the same? No, the four standard sizes (10, 13, 312, 675) each fit specific hearing aid types. Chemistry is consistent across reputable brands, all using zinc-air, but physical size and capacity vary.
Should I store hearing aid batteries in the refrigerator? No, room temperature storage in a dry place is best. Refrigeration can introduce moisture that interferes with the zinc-air chemistry and shortens shelf life.
Can rechargeable hearing aids replace disposable battery models? For mild to moderate hearing loss, rechargeable options like the Karthus unit work well and reduce ongoing costs. Users with severe loss or those needing precise clinical fittings still rely on disposable cells in professionally fitted aids.
How do I know when to change my hearing aid battery? Most aids emit a small warning tone or sound distorted when voltage drops. Some users notice reduced amplification or intermittent cutoffs before the formal warning, which is a cue to swap in a fresh cell.
