If you are looking for cochlear implant batteries 675 in New Zealand, the key step is to confirm your exact sound processor and battery module before you buy. Many cochlear implant users rely on high-power size 675 zinc-air batteries, often called implant plus batteries, but not every processor uses the same setup. We recommend matching the battery type to your processor guide, then choosing a trusted 675 option that suits your day-to-day routine.
For a quick starting point, browse our cochlear 675 collection or compare a dedicated implant option such as Zenipower cochlear implant size 675P.
What this page is for
This guide is for adults, family members, and caregivers who need help choosing cochlear implant batteries 675. It is especially useful when you know your device uses a disposable battery module, but you want to double-check size, understand what the 675 label means, and avoid buying the wrong pack.
What 675 means for cochlear implant batteries
Size 675 is a common battery size for high-power hearing devices. In many cochlear implant setups, a 675 battery refers to a high-power zinc-air button battery designed to handle the drain demands of certain sound processors. You may also see labels such as PR44, A675, or implant plus depending on the brand and packaging.
The most important point is that size alone is not the full compatibility check. Two packs can both say 675, but one may be a standard hearing aid battery while another is intended for cochlear implant use. That is why we suggest checking your processor manual or the battery recommendations from the manufacturer before ordering.
Who usually needs cochlear implant batteries 675
You are more likely to need this size if your processor uses a disposable battery module rather than a rechargeable pack. Some users keep 675 batteries as a backup even if they normally run a rechargeable system, especially for travel, long days out, or emergency use.
If you are not sure where to start, our broader guide to cochlear implant batteries in NZ can help you compare the main options before you choose a pack.
How to confirm your device size before you order
1. Check the processor model
Look at the exact name of the sound processor and its battery module. The model is usually printed on the processor, the battery holder, or the original packaging.
2. Check the user guide or manufacturer support page
This is the safest way to confirm whether your device uses disposable 675 zinc-air batteries, a rechargeable module, or another accessory setup. We recommend following the device maker's guidance rather than guessing from battery colour alone.
3. Check whether it specifies implant or implant plus
Some cochlear implant processors need high-power batteries intended for implant use. If your guide mentions implant, implant plus, or high-power 675 zinc-air batteries, choose a product made for that purpose.
4. Match the quantity to your routine
If you use disposable batteries every day, it often helps to keep extra cards at home, in a bag, and in the car. Families and caregivers often prefer a larger order so they are not caught short.
Colour codes and labels to watch for
Battery colour tabs help identify size, and size 675 is commonly associated with a blue tab. Even so, we do not recommend relying on colour alone because branding and labelling can vary. Always confirm the printed size code and the device guidance.

How long should a 675 cochlear implant battery last?
Battery life varies a lot by processor model, wireless use, streaming, program settings, and daily wear time. In practice, some users may get roughly a day from a set of disposable batteries, while others may see a shorter or longer result depending on the device and how hard it is working. The best guide is your processor manufacturer because expected run time can differ significantly across models.
If your batteries seem to be draining much faster than usual, check for a lifted tab before use, older stock, moisture exposure, or a processor issue. A sudden change in run time can also be a sign that it is worth reviewing your setup with your hearing professional or device support team.
Tips for swapping and storing 675 batteries
- Wash and dry your hands before changing batteries.
- Remove the tab only when you are ready to use the battery.
- Let a new zinc-air battery activate briefly after tab removal if your device maker advises this.
- Store spare batteries in a cool, dry place.
- Do not keep loose batteries in a pocket or bag where they can contact keys or coins.
- Keep both new and used batteries out of reach of children and pets.
Signs you may have bought the wrong battery
You may have the wrong product if the battery door does not close properly, the processor does not power up reliably, run time is unusually poor from the start, or the pack looks like a standard hearing aid battery when your processor guide calls for an implant version. In that situation, stop and re-check the processor documentation before using more of the pack.
When a rechargeable option may suit you better
Some cochlear implant users prefer rechargeable systems for convenience, while others prefer disposable 675 batteries for backup reliability, travel, or simpler replacement. There is no one best option for every person. We suggest using the setup that matches your processor, daily routine, and comfort level.
FAQs
Are all size 675 batteries suitable for cochlear implants?
No. Size 675 refers to the physical battery size, but some processors need a high-power implant-specific version. We recommend checking your exact processor guide before you buy.
How long should a 675 cochlear implant battery last with typical use?
It depends on the processor model, streaming, settings, and daily wear time. Some users may get around a day from a set, but the manufacturer's guidance for your device is the best reference.
Is the blue tab enough to confirm I have the right battery?
No. A blue tab is a common identifier for size 675, but you should still confirm the printed size code and whether your processor calls for an implant or high-power 675 battery.
Can I keep 675 disposable batteries as a backup if I mainly use rechargeables?
Often yes, if your processor supports a disposable battery module. Many users keep disposables for travel, emergencies, or long days away from a charger, but compatibility depends on the device setup.
