A 675 hearing aid battery is 11.6 mm by 5.4 mm, the largest of all hearing aid batteries. This is one of the most common hearing aid battery sizes on the market, used primarily in BTE (behind-the-ear) hearing aids and cochlear implants.
Hearing Aid Battery Color Codes – What Color is Size 675?
Manufacturers will often place letters before or after the size of a hearing aid battery. DieHard, for example, labels their size 675 batteries as PR675. Because remembering the dimensions and different makes of hearing aid batteries can be difficult, there is an industry standard color code for consumers to follow. The main hearing aid battery sizes and their corresponding colors are:
You can find these color codes on the product packaging, and on the air tab of the hearing aid if applicable. This tab keeps the battery fresh until you are ready to use it.
How Long Will Size 675 Hearing Aid Batteries Last?
A 675 hearing aid battery will usually last nine to 20 days, or an estimated charge of 300 hours. Since it is the largest hearing aid battery available, it tends to have the longest lifespan. The brand of battery, device, amount of time it is worn, amplification, and environmental factors can all play a role in how long your batteries will last. If your battery life is noticeably and consistently low, the culprit is more likely to be the device and/or usage rather than the battery itself.
How to Make Hearing Aid Batteries Last Longer
Even the best effort to extend the life of a hearing aid battery will only go so far. The fact of the matter is that you will need new batteries for your hearing aid often and regularly. However, there are a few things you can do to ensure you’re not wasting battery life:
- Do not remove the tab prior to use.
- Store hearing aid batteries at room temperature. It is not recommended to refrigerate or freeze them.
- Avoid storing batteries in extreme environments.
- Keep your batteries away from other metal objects.
- Purchase only fresh, quality batteries.
