Hearing aids run on tiny zinc-air coin cells, and the size 675 is among the most common for behind-the-ear and high-power models. When a battery dies mid-conversation or in the middle of a noisy restaurant, you feel it. Choosing the right cell means steady voltage from morning meetings to evening calls without the dreaded sudden cutout.

More Details On Our Top Picks
The PHILIPS 60-count pack is built for wearers who burn through size 675 cells on a tight schedule. A zinc-air chemistry (zinc-air cells activate once a small sticker is peeled and oxygen enters the vents) delivers a steady 1.45V output, which matters because hearing aids are voltage-sensitive and weak cells produce distorted sound before they finally quit.
Compare that to the smaller 24-pack later in this list: the bulk format here lowers the per-cell cost and means fewer reorder headaches for someone who depends on their device every waking hour. The trade-off is storage space, since 60 cells take up room in a drawer or travel kit.
What It Does Well
- Steady 1.45V output that avoids sudden mid-day cutouts during calls or meetings.
- 60-cell bulk format suits heavy daily wearers who want fewer reorders per year.
- Zinc-air chemistry tuned for wireless hearing aid features like streaming and noise processing.
- Tab-and-dial packaging makes single-cell removal straightforward without fumbling.
- Compatible with mainstream size 675 devices including A675, 675A, ZA675, and PR44 designations.
Things To Consider
- Once the tab is removed, the cell begins activating, so leaving peeled batteries sitting out shortens their usable life.
- Bulk packaging takes up more shelf space than a 12-pack like the Duracell later in this list.
- Newer listings may have limited long-term user feedback compared with more established brands.
Feature Snapshot
Made For
Heavy daily wearers who swap size 675 cells several times a week and want steady voltage without reordering constantly.
Consider Something Else When
Cochlear implant users should weigh the Power One option later in this list, since it is engineered specifically for implant-level drain.
The PHILIPS size 312 pack exists for a different category of device entirely: smaller in-the-ear and RIC (receiver-in-canal) models that physically cannot fit a 675 cell. Size 312 is a thinner, shorter cell, so anyone shopping here already knows their device demands this specific format.
Compared with the 675 cell earlier, this one is built for moderate-drain aids without heavy wireless streaming. A 24-count is a sensible middle ground for someone who doesn’t want the bulk packaging of a 60-cell tower yet still wants a couple months of supply on hand.
The Upside
- Smaller 312 format fits discreet in-ear devices that a 675 cell would never fit.
- 1.45V zinc-air output keeps sound consistent across a typical day’s wear.
- 24-count package suits moderate users who want a manageable supply.
- Cross-compatible with A312, 312A, ZA312, and PR41 designations.
Points To Note
- Size 312 cells run out faster than 675 cells in heavy streaming use, so power users may find 24 cells gone in weeks.
- Smaller dimensions can be trickier to handle during insertion, especially for users with limited dexterity.
Right Fit For
Owners of in-the-ear and RIC hearing aids who use a 312 cell and want a modest supply without committing to a 60-pack.
Look Elsewhere When
Behind-the-ear wearers on size 675 should grab the PHILIPS 60-count earlier in this list instead, since 312 cells won’t physically fit.
The ZeniPower kit stands out because it ships with a small keychain battery holder, a thoughtful touch for anyone who has fumbled a loose cell into a coat pocket or the bottom of a handbag. Sixty size 675 cells cover a long stretch for most daily wearers.
Zinc-air cells like these typically last two to ten times longer than older mercury-based chemistries, and a flat discharge curve means your hearing aid doesn’t need constant volume rebalancing as the cell drains. For travelers, the keychain holder is the real differentiator.
What Stands Out
- Bundled keychain holder lets you carry spare cells without loose batteries rattling in a bag.
- Flat discharge curve keeps volume levels consistent as the cell drains.
- Zinc-air chemistry offers long service life compared to older battery types.
- Sealed shelf life of roughly three years when tabs stay attached.
Trade Offs
- The keychain holder adds bulk to a keyring, which some users find awkward in a pocket.
- Sealed-tab longevity assumes the cell is stored in a cool, dry spot away from humidity.
Quick Facts
Who It Suits Best
Frequent travelers and commuters who need a spare cell within reach and prefer not to fish loose batteries out of a bag.
Where Another Pick Suits Better
Someone with arthritis or limited hand strength may find the Duracell EasyTab option later in this list easier to peel and install.
Duracell’s blue-tab 675 cells focus on a single practical problem: peeling and inserting tiny batteries. The extra-long tab is meaningfully easier to grip than standard short tabs, and the color-coding means you instantly know you’re grabbing the right size from a drawer of mixed cells.
Unlike the bulk 60-count PHILIPS earlier, this 12-pack trades volume for compactness and ease of opening. For someone who swaps a cell weekly or struggles with small parts, fewer cells in a lighter pack often matters more than per-unit savings.
Useful Touches
- Extra-long EasyTab makes peeling and installing easier for users with limited finger dexterity.
- Lightweight packaging is easier to open than bulk carded packs.
- Blue color-coding matches the industry-standard size 675 coding system.
- Long storage life when sealed, so spare packs stay good through slow-use periods.
Worth Noting
- Only 12 cells per pack, which means more frequent reorders for daily wearers than a 60-count option.
- The same long tab that helps with grip can snag on clothing when removing the battery.
Best Suited To
Wearers with arthritis, tremor, or any dexterity challenge who prioritize easy handling over maximum pack size.
Swap It Out When
Power-hungry aids with full-day streaming may chew through 12 cells faster than expected, in which case the VARTA 60-pack later in this list is a more cost-effective refill.
Power One’s size 675 cells are explicitly designed for cochlear implants, which draw considerably more current than standard hearing aids. The cell has to sustain continuous, high-drain output without dipping, since audio clarity on an implant depends on stable voltage.
Compare that to a generic hearing aid cell: most will technically work, but the discharge curve may sag earlier under implant load. Power One’s reputation in the implant community is the main reason these cells command attention, and the 60-cell format keeps refills infrequent.
Points In Its Favor
- Engineered specifically for cochlear implant power demands rather than generic hearing aid use.
- Strong reputation among implant wearers who depend on sustained, high-drain output.
- 60-cell bulk pack reduces the reorder frequency for daily users.
- Stable voltage curve supports consistent audio processing throughout the day.
Small Caveats
- Cells tend to cost more per unit than general-purpose hearing aid batteries.
- Packaging is functional but not designed for travel convenience like the ZeniPower keychain kit.
Feature Card
Who Should Grab It
Cochlear implant wearers who need cells rated for sustained high-drain output rather than general hearing aid use.
Not Your Match When
Standard hearing aid users without an implant will likely do just as well with the cheaper PHILIPS bulk pack earlier in this list.
VARTA’s Power One cells come with the kind of measured specifications most hearing aid batteries skip: a stated 1.45V nominal voltage and a typical capacity of 650 mAh. For users who want to compare cells on real numbers rather than marketing language, that data point is genuinely useful.
At 11.6mm in diameter and 5.4mm tall, these cells match the standard size 675 form factor used across most aids. The 60-pack makes sense for heavy users, and the zinc-air chemistry has the flat discharge behavior that keeps volume adjustments to a minimum throughout the day.
A Favorable Mix
- Published 650 mAh capacity gives a real benchmark to compare against generic cells.
- Standard size 675 dimensions fit mainstream behind-the-ear and high-power aids.
- Zinc-air flat discharge keeps volume consistent from fresh cell to depletion.
- 60-pack format means months of supply for typical daily wearers.
A Few Limitations
- Capacity rating is “typical” rather than guaranteed, so individual cell life will vary.
- Tab and packaging are functional but not as grip-friendly as the Duracell EasyTab design.
Spec Overview
Perfect Match For
Power-hungry hearing aids with continuous wireless streaming who want a cell with a documented capacity rating.
Reach For A Different Pick When
Cochlear implant wearers may prefer the Power One implant-specific cells earlier in this list, which are tuned for even higher drain.
Size 13 is one of the most common formats for behind-the-ear hearing aids, sitting between the larger 675 and the smaller 312. The PHILIPS 60-count here delivers the same 1.45V zinc-air stability as the size 675 variant earlier, but in a slightly smaller physical cell.
If your audiologist prescribed size 13, this is the format you actually need, since 675 cells won’t fit a size 13 compartment. The bulk packaging keeps the per-cell cost down for daily wearers, which matters over a full year of use.
A Few Strong Suits
- Bulk 60-count pack lowers per-cell cost for long-term wearers.
- 1.45V zinc-air chemistry supports stable daily output across streaming and standard modes.
- Cross-compatible with A13, 13A, ZA13, and PR48 size designations.
Honest Caveats
- Only fits size 13 compartments, so it is not interchangeable with the 675 cells earlier in this list.
- Newer product listing means less long-term user feedback than legacy brands.
Whose Shelf It Belongs On
Behind-the-ear hearing aid wearers who use size 13 cells and want a bulk supply to keep on hand.
Skip It When
Size 675 aid owners should stick with the PHILIPS 60-count earlier, since size 13 cells are physically smaller and won’t fit.
Size 10 is the smallest standard zinc-air cell, designed for the most discreet hearing aids: mini RIC (receiver-in-canal) and CIC (completely-in-canal) models that sit almost invisibly in the ear canal. Tiny aids need tiny power sources, and that’s exactly what this format delivers.
Compared with the larger 675 cell earlier, size 10 has less capacity per cell, which means shorter runtime between swaps. The 60-count bulk pack is a sensible move because daily wearers of mini aids go through these cells quickly.
What Earns Its Place
- Compact size 10 format fits the smallest, most discreet hearing aid models on the market.
- Bulk 60-count format suits frequent replacement needs typical of size 10 wearers.
- 1.45V zinc-air output supports wireless features found in modern mini aids.
- Cross-compatible with A10, 10A, ZA10, and PR70 size designations.
Things To Weigh
- Size 10 cells have the shortest runtime per cell of any standard hearing aid battery size.
- Very small dimensions make handling harder without a steady grip or fine motor control.
Built With In Mind
Wearers of mini RIC and CIC hearing aids who rely on the smallest cell format and swap cells frequently.
A Better Fit Elsewhere
Users with arthritis or shaky hands will likely find the Duracell EasyTab option earlier easier to handle, even at the cost of fewer cells per pack.
What To Know Before Restocking Your Size 675 Cells
Match The Cell Size To The Aid
The single biggest mix-up is grabbing the wrong format. Size 675 cells are blue-tabbed and physically larger than size 312 (brown) or size 13 (orange), so they will not seat in a compartment designed for a smaller cell. Check your audiology paperwork or the inside of the battery door for the printed code before reordering.
Read Voltage As A Stability Signal
Most hearing aid cells list 1.45V, which is the standard nominal voltage (the average operating voltage the cell maintains under typical load). What matters more in practice is how flat the discharge curve stays as the cell drains. A cell that sags early will cause distortion before it dies, leaving you thinking the hearing aid is broken when really the battery is on its way out.
Check Capacity When It Is Published
Some manufacturers, like VARTA’s Power One line, publish a typical capacity in mAh (milliamp-hours, a measure of how much energy the cell stores). Higher numbers mean longer runtime per cell under similar load. When capacity isn’t listed, you are relying on real-world user reports to gauge longevity.
Size Up The Tab And Packaging
For anyone with limited dexterity, the tab length and pack design matter as much as the cell itself. The Duracell EasyTab option is a good reference point for what grip-friendly looks like, and a keychain holder like the ZeniPower kit keeps spares from rattling loose in a bag.
Picking The Right Pack Without Overthinking It
Common Shopping Slip Ups
The most frequent mistake is buying a larger or smaller cell than the aid actually needs, since the color coding on the tab is the only reliable size identifier. Another trap is assuming the cheapest bulk pack is always the better deal: per-cell cost only matters if the cells actually perform in your specific device. For heavy streamers, a low-grade cell that sags early will cost you clarity, not just money.
What The Higher Tier Buys
Premium cells, like the Power One cochlear implant line, cost more because they are tuned for sustained high-drain output rather than intermittent use. If your hearing aid streams audio all day or runs a cochlear implant, the upgrade pays for itself in fewer mid-day cell swaps. For quieter devices with lighter drain, a standard zinc-air cell in a 60-count pack is usually enough.
Frequently Asked Questions
How Long Does A Size 675 Hearing Aid Battery Typically Last?
Most size 675 cells last between 5 and 14 days depending on streaming hours, output level, and wireless feature use. Heavy streamers at high volume see the lower end of that range.
What Does The Color Of The Tab Mean?
The tab color is the industry-standard size code, and blue means size 675. Brown is 312, orange is 13, and yellow is 675 for cochlear implants in some markets. Always match the tab color to your device, not just the printed number.
Can You Reuse A Zinc-Air Cell After Removing The Tab?
Once the tab is peeled, oxygen enters the cell and activation begins, so it cannot be resealed and stored indefinitely. The cell will keep working until its charge is spent, but it cannot be revived by reattaching the tab.
Do All Size 675 Cells Work In Cochlear Implants?
Cells designed for standard hearing aids will technically fit a cochlear implant, but cells engineered for implant-level drain, like the Power One implant line, hold voltage more reliably under heavy current draw. For daily implant use, the dedicated cells are the safer pick.
How Should You Store Spare Hearing Aid Batteries?
Keep spare cells at room temperature in their original sealed packaging, away from humidity and direct sunlight. A bedside drawer or a small keychain holder like the ZeniPower kit works well for short-term carry.
Closing Remarks
The right size 675 hearing aid battery comes down to matching the cell to your specific device and use pattern. Heavy streamers and implant wearers benefit from premium cells with documented capacity and high-drain engineering, while occasional wearers can lean on bulk 60-count packs for the best per-cell value. Pick based on how your aid actually gets used day to day, and you’ll spend less time swapping cells in awkward moments.
