Batteries for Health Devices

Hearing aids, thermometers and blood pressure monitors all stop working when the battery runs out, usually at the least convenient moment. This range brings together Duracell hearing aid batteries in sizes 10, 312 and 675, coin cell batteries such as 2032 and 2430, and AA and AAA batteries for home health devices.

Hearing aid batteries are colour coded, so size 10 has a yellow tab, 312 a brown tab and 675 a blue tab, matching the colour on your hearing aid packaging. They are zinc-air batteries, which start working once the tab is removed, so peel the tab off and wait a minute before fitting. Coin cells and AA or AAA batteries are listed in your device's manual or on the battery cover. Keep spare batteries in their packaging and out of reach of children, as button and coin batteries are dangerous if swallowed.

All batteries here are stocked at Leahy's Pharmacy, a family-run Irish pharmacy in Tralee, Co. Kerry. Recycle used batteries rather than putting them in household waste. If you look after a hearing aid, see our ear care range.

Frequently Asked Questions

Which hearing aid battery size do I need? +
Check the size printed on your hearing aid, its manual or your previous battery pack. Sizes are colour coded across brands: size 10 is yellow, 312 is brown and 675 is blue. Size 675 is usually used in larger, more powerful hearing aids, while 10 suits the smallest models. Your audiologist can also confirm the right size.
Why should I wait after removing the tab? +
Hearing aid batteries are zinc-air batteries, which use air to power up once the coloured tab is removed. Waiting about a minute before closing the battery door gives them time to activate fully, which can help them last longer. Only remove the tab when you are ready to use the battery, as it starts to run down once exposed to air.
Which battery does a thermometer or blood pressure monitor use? +
Digital thermometers often use a coin cell such as 2032 or 2430, while blood pressure monitors usually take AA or AAA batteries. The exact type is listed in the device manual or printed inside the battery cover. Replace all batteries in a device at the same time, and remove them if the device will not be used for a long period.
Are button and coin batteries safe at home? +
Button and coin batteries can cause serious internal injuries if swallowed, so store spares in their original packaging, out of sight and reach of children, and dispose of used ones promptly. If you think a child has swallowed a battery, seek urgent medical help straight away. Used batteries should be recycled rather than thrown in household waste.
