Hearing aid batteries are colour-coded: size 10 (yellow), 312 (brown), 13 (orange) and 675 (blue). Match the colour and number on your current battery or check your hearing aid manual. Browse the full Batteries range.

Battery life depends on size and how much your hearing aid is used, but smaller sizes generally last fewer days than larger ones. Streaming audio and higher amplification settings shorten runtime.

Zinc-air cells need air to activate. Waiting about a minute after pulling the tab lets the battery reach full power before use, which can improve overall battery life compared with inserting it immediately.

Once the tab is removed, the cell begins activating and re-applying the tab won't fully stop the process. It's best to remove the tab only when you're ready to use the battery to avoid wasting it.

Keep them at room temperature with the tabs on, in a dry place away from coins, keys and other metal that could short them. Avoid the fridge, as condensation can harm the cells.

No, like other small button cells they're a swallowing hazard. Store them out of reach of children and pets, and dispose of used batteries safely rather than leaving them within reach.
