    Up to 4 years of shelf life. Will power your hearing aid for 7-14 days once opened.

    How do I know which batteries I need fo my hearing aid?

    Hearing aid batteries come in standard sizes - no matter which make of hearing aid you have (Phonak, Starkey, Widex, Unitron, etc) it will use one of the industry-standard battery sizes. To make things easier to remember, batteries are color-coded, the ones on sale here are ORANGE, also known as size 13.

    If you are not sure which size you need check the packet/card that your current batteries came in, the packaging will clearly show the colour. If you do not have a packet/card then you may have a battery with the "tab" still on, which will also be colored for the size. No packaging and no tab on your battery? Look closely at the battery itself, printed on one side will be the size of the battery - the text will be quite small to read. Once you've found the size of your battery use the chart below to determine the color you need:

    Size 675 Blue
    Size 13 Orange
    Size 312 Brown
    Size 10 Yellow

    We also supply Rayovac size 675 / blue, Rayovac size 10 / Yellow and Rayovac size 312 / brown batteries.

    How long will a battery last for?

    The annoying answer is: it depends. I change my own hearing aid batteries every Monday and they last the 7 days without fail, I have a severe hearing loss so my aids are woking hard for me and draining the battery. You should expect a battery to last between 7-14 days, depending on how long you use them each day.

    How do I change the battery in my hearing aid?

    Battery care.

    If you use a dehumidifier for your hearing aids you should always remember to remove the batteries before putting your aids in to dry out - leaving the batteries in can reduce their lifespan considerably.

    Hearing aid batteries are "zinc air" batteries, which means that they are activated when you pull the tab off of them - they can hold their charge for years if the tab is left on but once you pull the tab off they are activated and their 7-10 lifespan starts ticking down regardless of whether you put them in your hearing aid or not. Putting the tab back on the battery once it has been taken off will not prolong their lifespan, as soon as the tab is off and they are exposed to the air they begin working.
