What is an LR44 battery used for?

An LR44 is a round, flat, 1.5-volt button-type battery used for watches, digital thermometers, and calculators. You also find them in some flashlights, laser pens, security system panels, and home medical equipment like blood glucose monitors. When changing an LR44 battery in your device, line up the negative side—which usually has a small circular protrusion on it—with the negative marking on the device. The positive side of the battery is usually flat.

Can you replace an LR44 battery with a 357?

These two batteries are the same size, so they can sometimes be used interchangeably, but the performance may be different. The LR44 is an alkaline battery designed to last longer in low-use devices like a watch. A 357 battery is silver oxide battery designed for devices that need a constant voltage, such as precise calipers. For best results, choose the type of battery specified by the device manufacturer.

How long does an LR44 battery last?

An LR44 battery has a shelf-life of six to eight years. Once you install it in your device, its lifespan will be determined by how much it's used. In a watch, the battery should last one to two years.
