How to get the best price
1. Compare cost per battery
A cheaper pack is not always better value. Divide the total price by the number of batteries to find the real cost.
2. Buy in bulk
Larger packs often reduce the per unit price significantly, especially if you use your hearing aids daily.
3. Consider reliable alternative brands
Premium brands are not always necessary. Many users find mid range brands perform similarly for everyday use.
4. Avoid expired or near expiry stock
Cheap batteries are not a good deal if they lose charge quickly. Always buy from reputable NZ suppliers.
Tips to make your batteries last longer
- Let the battery sit for 1 to 2 minutes after removing the tab before inserting
- Store batteries in a cool, dry place
- Turn off your hearing aid when not in use
- Keep batteries away from metal objects
Common mistakes to avoid
- Buying the wrong size due to colour confusion
- Choosing based only on pack price
- Storing batteries in humid environments like bathrooms
