Which type of battery do I have to buy for my pen type thermometer when the battery is empty?

If you use the thermometer for home use, you need not worry about battery exchange probably because the installed battery may last for 3 to 5 years!

If you need a new battery, we recommend you ask for a 'SR41' round cell battery. "41" is a code for the battery size; 'LR' batteries are also suitable but have a shorter lifetime. We recommend that you take the old battery with you so you purchase the right one.
