| Product Safety Data Sheet |
|
|
|
| Maxell is the first company in Japan to successfully market button-type silver oxide batteries. Based on many years of experience and
know-how in various fields, the SR battery is suitable for precision electronic devices such as quartz watches, where high-energy density
per unit volume and a stable operating voltage are required. Various product lineups are available to meet the growing need for supplying
power to various types of watches, ranging from large to compact, thin models.
Zero-mercury, zero-lead added types are also available. For more information, please contact Maxell. |
| The button-type silver oxide battery uses silver oxide (Ag2O) as its positive active material and
zinc (Zn) as its negative active material. Potassium hydroxide (KOH) (W-type) or sodium hydroxide (NaOH) (SW-type)
is used as an electrolyte. |
| • |
Flat discharge characteristics
A flat discharge curve during discharge supplies a stable voltage until the end of the discharge life. |
| • |
High-energy density
High-energy density per unit volume provides approx. twice as the amount of energy capacity as button-type alkaline
batteries. |
| • |
Excellent discharge load characteristics
Employing an alkaline electrolyte, the SR battery features excellent discharge load characteristics. Depending
on the composition of the electrolytes, two models are available; (1) a low-drain type for analog watches,
and (2) a high-drain type for multi-function watches incorporating an alarm, illumination light, etc. |
| • |
Superior leakage* resistance
Featuring Maxell's original leak-resistant processing, the SR battery has excellent leakage resistance, which
suppresses the electrolyte from rising up and seeping out — a basic phenomenon of alkaline electrolytes.
(* Leakage is defined as an unintended escape of liquid from a battery.) |
