I make sure it matches the device I’m using, whether it’s a watch, calculator, thermometer, toy, or small electronic gadget.

Understanding the LR44 Battery
The LR44 is a small alkaline button cell battery that delivers 1.5 volts. I’ve found it is commonly used in compact devices that need steady, low-power energy. It may also be sold under other names like AG13, A76, 357A, or L1154, so I always double-check the label before buying.

My Tips for Storage and Use
