675 implant plus batteries are high power zinc-air batteries commonly used with some cochlear implant sound processor setups. In NZ, the key step is matching the battery type your processor manual or clinician recommends, because 675 and 675P are not always interchangeable across every system. We recommend checking your processor guide first, then ordering the exact size and type you need.
Who this guide is for
This guide is for people using cochlear implant battery systems that require high power disposable zinc-air cells, along with family members and carers helping with reordering, storage, and day-to-day battery changes. If you want to browse suitable options first, see our cochlear 675 collection or go straight to Zenipower cochlear implant size 675P.
What 675 implant plus batteries usually mean
When people search for 675 implant plus batteries, they are usually looking for the larger blue-tab zinc-air batteries designed for higher-drain hearing devices and some cochlear implant processors. These are often referred to as size 675, PR44, or 675P depending on the manufacturer and product format.
The important part is not just the number. Some processors use a battery module or cartridge designed for a specific disposable battery format, and some brands specifically call for 675 Power Implant batteries. That is why we recommend confirming the exact wording in your user guide, current packaging, or clinician notes before reordering.
How to confirm compatibility
Check your current battery pack or sleeve
If your current pack says 675P, Power Implant, or PR44 high power, start by matching that wording as closely as possible. The blue colour code is helpful, but the printed battery type matters more than colour alone.
Check your processor manual
Manufacturer instructions often state whether your processor uses one or two disposable batteries, and whether it needs a standard 675 or a power implant version. For example, some cochlear implant systems specify 675 Power Implant batteries, while others use two size 675 zinc-air batteries in a dedicated battery module.
Use the battery hub as a cross-check

How size and colour codes work
Disposable hearing device batteries are usually identified by both a number and a tab colour. Size 675 is typically the blue-tab option and is one of the larger disposable formats. That larger size helps support devices with higher power demands.
Still, the same size number does not remove the need for compatibility checks. Battery chemistry, drain profile, housing, and processor design can all affect what is suitable for your setup. We see many shoppers focus on the number first, but the safest route is always matching the exact specification your device already uses.
Practical tips for changing and storing 675 implant plus batteries
Wait briefly after removing the tab
Zinc-air batteries activate once air enters the cell. A short wait after removing the tab can help the battery activate properly before insertion, following the guidance that comes with your processor or battery brand.
Store them in a cool, dry place
Avoid storing disposable batteries in damp rooms, direct sun, or very hot places such as a parked car. Keep the tab on until you are ready to use the battery.
Do not mix old and new batteries
If your battery module uses more than one cell, replace the set together rather than mixing part-used and fresh batteries.
Keep spare batteries sealed and out of reach of children
Even though zinc-air hearing batteries are common in hearing technology, button and coin batteries still need careful storage and disposal. Keep them in original packaging where possible and follow local disposal guidance.
Common reasons battery life feels shorter
- Streaming or higher daily processor use
- Leaving the tab off long before insertion
- Humidity or poor storage conditions
- Using the wrong battery type for the device
- A battery module or contact issue rather than the battery itself
If battery life suddenly changes, it can be worth checking both the battery type and the processor setup before assuming the batteries are faulty.
When to ask for extra support
If the label on your current pack is unclear, your processor has changed, or you are between rechargeable and disposable options, it is sensible to confirm compatibility before buying in bulk. That is especially useful if your sound processor uses a specific cartridge, sleeve, or manufacturer-approved battery format.
FAQs
How do I know which size I need?
Check your current battery pack, processor manual, or clinician guidance. For cochlear implant systems, we recommend matching the exact battery size and type already specified, such as 675 or 675P, rather than choosing by colour alone.
Are 675 and 675P batteries the same thing?
Not always. Some brands and devices use the terms differently, and some cochlear implant systems specifically call for a power implant version. We recommend following the wording in your processor documentation before ordering.
Can I use standard hearing aid 675 batteries in a cochlear implant processor?
Sometimes, but not in every setup. Some processors are designed around high power or implant-specific disposable batteries, so the safest approach is to confirm compatibility with your device guide or hearing professional first.
How should I store spare 675 implant plus batteries?
Keep them sealed, dry, and at room temperature until needed. Avoid moisture, excessive heat, and loose storage in bags or drawers where the batteries can be damaged or accessed by children.
