Engangsbatteri Varta V301

The Varta V301 is a single-use SR43 silver-oxide battery that delivers stable 1.55 V power for small electronic devices. Presented in a single-piece blister, this button/coin cell is engineered for applications where compact size, consistent voltage and low self-discharge are required. Its chemistry and construction provide reliable output throughout the discharge cycle, making it suitable for precision devices that demand steady performance.

Advantages

The silver-oxide chemistry of the Varta V301 offers a flat discharge curve and predictable voltage under load, which helps maintain device accuracy. The compact SR43 form factor fits a wide range of watches, calculators and compact electronics. Supplied in individual packaging, the battery is protected from shorting and humidity until first use, ensuring shelf stability and ease of handling.

Suitable for

• Wristwatches and watch movements
• Calculators and small handheld devices
• Small medical devices with button cell requirements (non-rechargeable)
• Key fobs, small sensors and backup memory modules

Key specifications

• Nominal voltage: 1.55 V
• Size designation: SR43
• Quantity: 1 piece per package

How to use

Confirm the SR43 battery size and 1.55 V requirement in your device's manual before installation. Ensure correct polarity when inserting the battery: the positive side is typically the flat, marked face. Avoid forcing the battery into the compartment; if it does not seat easily, re-check orientation and compatibility. Dispose of used batteries according to local regulations for single-use silver-oxide cells and replace with the same size and chemistry to preserve device function.

Recommendations

Store unused batteries in their original blister at room temperature, away from direct heat and metal objects that could cause short circuits. Keep out of reach of children and do not attempt to recharge, puncture, or heat single-use silver-oxide batteries.
