Using our answers
We take battery sizes and specs from the makers’ datasheets and check them carefully, but mistakes can happen. Always check your device’s manual or the old battery before buying, especially for medical devices.
Safety
Coin and button batteries are dangerous if swallowed. Keep them away from children and pets, and follow the safety advice on each page and on the pack. Our emergency page is general guidance, not medical advice.
