Maxell Silver Oxide Battery

329 SR731SW Button Cell

The Maxell silver oxide battery is available for sale in a variety of sizes to accommodate your varying power needs. This 329 button cell provides a 36mAh capacity that is ideally meant for use in low-drain electronics, such as an analog watch or a key-less entry remote for a car. While the 36mAh capacity is quite low, when compared with other household power sources, this specialty-sized battery is designed specifically for these smaller-sized electronic devices that we may otherwise take for granted. What sets this silver oxide battery apart from others is its flat discharge rate. Disposable alkaline cells, on the other hand, have a gradual, sloping discharge curve where the voltage lowers over time. The Maxell silver oxide battery provides a stable discharge that maintains the 1.55 voltage throughout the discharge cycle for optimum performance.

Maxell is a worldwide supplier of specialty button cell batteries. With their leak-resistance makeup and mercury-free formula, this 329 battery, or SR731SW button cell, is sure to satisfy your watch-powering needs. This non-rechargeable cell is sold individually; however, it is packaged in tear strips of five batteries. When placing an order, one unit is equal to one battery. For best results, we recommend buying the Maxell 329 SR731SW in multiples of five. For larger orders, the five-piece tear strips are packed in boxes of 100 (20 x five-piece tear strips.)
