Description
Maxell SR920SW Bulk Batteries
Button Cells for Watches
Maxell SR920SW button batteries are sold in bulk quantities and are exclusively available for sale to US original equipment manufacturers, or OEM, for inclusion within their products' packaging. These button-type cells use silver oxide as the positive active material to create a flat discharge rate that stabilizes the voltage. When you power your electronics with silver oxide batteries, you will receive continuous and steady power, unlike with alkaline cells, which typically drop off over time. These Maxell 371 button batteries are ideally meant for use within watches; however, they are also compatible with many other low-drain electronics, such as some calculators and medical instruments.
Features:
- Flat discharge curve powers your electronics for the duration of the battery's life.
- High energy density is suitable for precision electronic devices - double the capacity of alkaline.
