How do you measure a button battery?
To measure a button battery, you will need a digital caliper. A digital caliper is a tool that measures the thickness, diameter, and length of an object with high accuracy. To measure a button battery, follow these steps:
1. Turn on your digital caliper and set it to measure in millimeters.
2. Place the button battery on a flat surface and press it down with your finger.
3. Use the caliper to measure the diameter of the battery at its widest point.
4. Measure the thickness of the battery by placing the caliper on the side of the battery and closing it until it touches the other side.
5. Finally, measure the length of the battery by placing the caliper on the top of the battery and closing it until it touches the bottom.
What size is a 1.5V button cell?
A 1.5V button cell battery is commonly known as an LR44 or AG13 battery. It is used in a variety of devices, including calculators, watches, and toys. The dimensions of an LR44/AG13 battery are 11.6mm in diameter and 5.4mm in thickness.
In conclusion, understanding the different sizes of button batteries is essential to ensure that your device works correctly. By using a digital caliper to measure the diameter, thickness, and length of the battery, you can choose the right size and type of battery for your device. Remember to always check the battery size and type indicated on your device’s manual or label before making a purchase.
