Quick answer: hearing aid battery prices in NZ depend on the battery size, brand, pack quantity, shipping threshold and whether you buy a compare pack, a single-brand bulk box or a subscription. For the best value, we recommend buying the correct size in bulk from live product pages, starting with Shop Hearing Aid Batteries, then checking the matching size collection or product page before checkout.
If you already know your battery size, the fastest path is to choose it now: Size 10 hearing aid batteries, Size 312 hearing aid batteries, Size 13 hearing aid batteries, Size 675 hearing aid batteries or Cochlear 675 batteries. If you are buying for a parent, partner or first-time user, a compare pack can reduce the guesswork before you commit to a larger repeat order.
Why hearing aid battery prices vary
Two people can search for hearing aid battery prices and need very different products. One person may use a small size 10 battery in a discreet aid. Another may need size 675 or cochlear 675P for a higher-power device. Price also changes by brand, quantity and whether you are buying one size or mixing several sizes for a household.
Before comparing prices, check the battery number on your current tab or packaging. The usual colour guide is size 10 yellow, size 312 brown, size 13 orange and size 675 blue. If you use a cochlear implant processor, do not assume a normal 675 battery is the right option. Check your device instructions, then start with Zenipower Cochlear Implant Size 675P or the Cochlear 675 collection if that is the size your device requires.
Bulk buy hearing aid batteries options
Bulk buying is usually the easiest way to reduce repeat ordering, avoid emergency purchases and keep spare batteries in the places you actually need them, such as a handbag, bedside drawer, carer kit or travel bag. The key is to bulk buy the right size, not simply the cheapest listing.
Option 1: Compare packs for first-time buyers
Compare packs are useful when you know the size but want to try more than one brand before choosing a regular bulk order. HearNZ has compare packs across the common sizes:
- Compare Pack Size 10 PowerOne Rayovac and ZeniPower
- Compare Pack Size 312 PowerOne Rayovac and ZeniPower
- Compare Pack Size 13 PowerOne Rayovac and ZeniPower
- Compare Pack Size 675 PowerOne Rayovac and ZeniPower
We recommend compare packs when you want confidence before buying a larger quantity. They are also practical for families helping someone reorder, because you can test what fits the routine without changing the battery size.
Option 2: Bulk buy by size
If you know the size, shop by battery number first. This keeps price comparison simple and reduces the risk of buying a great deal that does not fit your device.
| Battery size | Best place to compare prices | Popular product pages |
|---|---|---|
| Size 10 yellow | Shop Size 10 | Power One Size 10, Rayovac Size 10, Zenipower Size 10 |
| Size 312 brown | Shop Size 312 | Power One Size 312, Rayovac Size 312, Zenipower Size 312 |
| Size 13 orange | Shop Size 13 | Power One Size 13, Rayovac Size 13, Zenipower Size 13 |
| Size 675 blue | Shop Size 675 | Power One Size 675, Rayovac Size 675, Zenipower Size 675 |
Option 3: Bulk buy by brand
Some customers prefer to stay with one brand once they know it suits their device and routine. You can compare live options by brand here: Power One hearing aid batteries, Rayovac hearing aid batteries and Zenipower hearing aid batteries. Where a product page shows mix-and-match bulk buying across a brand range, use that page to build a practical order for more than one battery size.
Option 4: Subscription or repeat ordering
If you know the exact size and you replace batteries regularly, a repeat order can be easier than waiting until the last card is opened. Start with Subscription Products or read HearNZ Subscriptions. This is especially useful when a carer, family member or clinic administrator helps keep supplies topped up.
How to compare hearing aid battery prices without wasting money
We suggest comparing price by correct size first, then by brand and quantity. The lowest listed price is not the best value if it is the wrong battery, too small an order, or a product you will not use before you need a fresh sealed card.
Use this buying checklist
- Confirm the battery number from your existing tab, old packet or hearing aid manual.
- Choose the matching size collection, such as Size 312 or Size 13.
- Compare the product page for your preferred brand, such as Rayovac Size 312 or Power One Size 13.
- Check whether a compare pack or bulk option gives better value for your household.
- Consider adding a Rayovac Hearing Aid Battery Tester if you often wonder whether the aid or the battery is the problem.
Best picks by buying situation
I want the safest first order
Choose a compare pack in your size. This is ideal when you are helping a loved one and do not want to guess between brands. Start with Compare Pack hearing aid batteries, then reorder the brand and size you prefer.
I already know my battery size
Go straight to the product page and choose the quantity that suits your routine. Common repeat-order paths include Zenipower Size 312, Rayovac Size 13, Power One Size 675 and Zenipower Size 10.
I use batteries quickly
Look at bulk or subscription-friendly options rather than buying one small quantity at a time. The main shop page, Shop Hearing Aid Batteries, is the simplest place to compare sizes, brands and live product pricing in one view.
Battery life, storage and safety
Hearing aid batteries are small zinc-air button batteries. Keep the tab on until you are ready to use the battery, then give it time to activate before inserting it. Store spare batteries in a cool, dry place, away from loose metal objects, children and pets. Open the hearing aid battery door overnight when appropriate for your device, because this can help reduce drain and moisture build-up.
Button batteries can be dangerous if swallowed or placed in the nose or ear. Product Safety New Zealand advises that a swallowed or inserted button battery can cause serious irreversible damage quickly. If this happens, seek urgent medical help immediately. This safety point matters even when a battery seems used, because old batteries can still be hazardous.
FAQs
What is the best way to compare hearing aid battery prices in NZ?
The best way is to compare the correct size first, then compare brand, quantity, shipping threshold and any bulk buy option shown on the product page. A cheaper listing is not good value if the battery does not match your hearing aid.
Should I buy hearing aid batteries in bulk?
Bulk buying makes sense when you already know your correct battery size and use batteries regularly. It can reduce repeat ordering and help you keep spares at home, while still keeping unopened tabs sealed until use.
Which hearing aid battery size should I buy?
Buy the size printed on your current battery tab, packet or hearing aid instructions. Common colour codes are size 10 yellow, size 312 brown, size 13 orange and size 675 blue.
Are compare packs worth it?
Compare packs are worth considering when you know the size but want to try Power One, Rayovac and Zenipower before choosing a repeat bulk order.
Can I mix sizes in a bulk order?
Some product pages show mix-and-match bulk buying across the same brand range. Check the live product page for the current quantity rules before checkout.
How should I store spare hearing aid batteries?
Store spare batteries sealed, dry and away from heat, moisture, children, pets and loose metal objects. Do not remove the tab until you are ready to use the battery.
What should I do if a hearing aid battery is swallowed or inserted?
Seek urgent medical help immediately. Button batteries can cause serious harm quickly, even if the battery is small or partly used.
