How to change a watch or button battery
Most button batteries can be changed at home in a few minutes.
1. Find the size
Open the battery cover and read the code printed on the old battery, such as LR44, SR626SW or CR2032. Type it into our battery guide to find the equivalents. Our talking wristwatches use L1131F (also sold as LR1130 or AG10).
2. Open the case
Some watches have small screws on the back, others a back that twists or pops off. Use a small screwdriver or a case knife, and work over a towel so nothing rolls away. If the back is pressed on tightly, a watch shop can change the battery quickly.
3. Swap the battery
- Note which way up the old battery sits. The flat side marked + usually faces up.
- Handle the new battery by its edges. Skin oil can shorten its life.
- Press it gently into place and close the case.
4. Check it works
For a talking watch, press the button to hear the time, then set the time again if needed.
5. Recycle the old battery
Don't put button batteries in the bin. Put tape over both sides and take them to a battery recycling drop-off. Many supermarkets and hardware stores have one.
Warning: keep button and coin batteries away from children. Swallowing one can cause serious injury within hours. If you think a battery has been swallowed, get urgent medical help straight away.
