Maxell Silver Oxide Watch Batteries for High Drain Devices

The 399, or SR927W, is a popular Silver-Oxide cell commonly used in watches, with a shelf life of 5+ years. Other applications may include calculators, film cameras, medical instruments, cash registers, or FA Instruments (Measuring Instruments, Onboard Microcomputers, Sensors). High Drain batteries are for applications with a continuous, low power consumption and occasional high peaks: Analog and digital watches with extra functions (backlight, alarm), pocket calculators, electronic games, cameras, etc. This is in comparison to low drain batteries, which are best used in devices that use a small amount of power over a long time: Analog watches, TV remotes, alarm clocks, etc.

The 5PK Maxell Silver Oxide SR927W High Drain Watch Battery is a popular choice for various applications. It features a Silver Oxide chemistry, a Nominal Voltage of 1.55V, and a Nominal Capacity of 57(mAh). The Nominal Discharge Current is 100 (?A), and the battery has a Diameter of 9.5 mm and a Height of 2.7 mm.

Some of the key features of the 5PK Maxell Silver Oxide SR927W High Drain Watch Battery include:

Flat Discharge Characteristics: The battery has a flat discharge curve during discharge, supplying a stable voltage until the end of the discharge life.

High-Energy Density: The high-energy density per unit volume provides approximately twice the energy capacity of 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: a low-drain type for analog watches, and 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.

The dimensions of the 5PK Maxell Silver Oxide SR927W High Drain Watch Battery are as follows: Length: 0.1000, Width: 0.3700, Height: 0.1000, Diameter: 0.37. It is compatible with various watch models, including the 399 / 395.
