## Long description

The Energizer 384/392 is a single-use silver-oxide button cell that provides a nominal voltage of 1.55 V in a compact 7.9 mm × 7.9 mm × 3.6 mm housing. Designed for devices that require stable voltage and long shelf life, this battery combines silver-oxide chemistry with a multi-drain performance profile to suit both low-drain and high-drain applications. With a rated capacity of 45 mAh and a silver-coloured finish, it is intended for reliable short- and medium-duration powering of small electronic devices.
Advantages
Silver-oxide chemistry ensures a consistent voltage output over most of the discharge cycle, supporting accurate timekeeping and predictable device operation. The multi-drain design offers balanced performance in both low-drain devices, such as simple watches, and higher-drain gadgets that occasionally demand more current. Its small coin form factor and modest capacity make it suitable for compact assemblies where space is limited and reliable single-use power is required.
Suitable for
 Wrist and pocket watches (analog and some digital models)
 Calculators and basic handheld electronic tools
 Small medical devices and measuring instruments (e.g., glucose monitors, thermometers)
 Key fobs, remote controls for small devices, and small LED lights
 Other compact electronic gadgets requiring a 1.55 V button cell

How to use
Install the battery into the device following the manufacturer's polarity markings and the device user manual. Ensure the battery sits flat and that contacts are clean and free of corrosion before closing the battery compartment. For devices with spring or clip contacts, apply gentle pressure until the battery makes secure contact. Do not attempt to recharge single-use cells; they are not designed for recharging and attempting to do so can cause leakage or rupture.
Usage recommendations
Store unused batteries in a cool, dry place away from direct sunlight and metal objects that could short them. Replace batteries in pairs when a device uses multiple cells and dispose of used cells according to local battery recycling regulations. If a battery shows signs of leakage, remove it carefully using protective gloves and clean the compartment before inserting a new cell.
