Product Description

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.

2, Superior leakage* resistance
Featuring HUGE'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.
Product list

* Nominal capacity indicates the duration until the voltage drops to 1.2V when discharged at a nominal discharge current at 20 deg. C.

3,Principle and reaction:

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.

4, Applications:

Film Cameras
Medical Instruments, Cash Registers
FA Instruments (Measuring Instruments, Onboard Microcomputers, Sensors)
