Precision energy for demanding applications

The Varta V357 / V13GS button cell is the ideal energy supplier for all devices that require constant and reliable voltage. It is used in high-quality wristwatches, medical devices such as blood glucose meters or digital fever thermometers, precise measuring instruments like digital calipers, and professional camera equipment. Its stable performance ensures the accurate function of your sensitive electronics.

Superior silver oxide technology

The silver oxide technology used (Ag2O/Zn) is superior to alkaline batteries in several respects. It offers a higher nominal voltage (1.55 V compared to 1.5 V) and, above all, a much more stable discharge curve. This means the voltage remains consistently high over almost the entire lifespan of the battery, which is essential for precise measurements. It also features excellent leak protection and very long shelf life.

Efficiency and safety with system

Varta batteries are subject to the strictest quality controls to guarantee consistently high performance and maximum safety. The V357 / V13GS is designed for a wide temperature range and reliably supplies energy even under demanding conditions. Individual packaging protects the cell from short circuits and environmental influences until use.

FAQs about the Varta V357 / V13GS / SR44 button cell

Can I replace an LR44 battery with an SR44 (V357 / V13GS)?

Yes, in most devices this is easily possible and is often even an upgrade. The SR44 (V357 / V13GS) offers a more stable and slightly higher voltage, which can improve the accuracy of measuring devices or watches. Conversely, an SR44 should not always be replaced by an LR44 if the device requires constant voltage.

What do the designations V357, V13GS and SR44 mean?

These are various designations for the same silver oxide battery size. SR44 is the international IEC code. V357 and V13GS are both Varta model numbers for this cell, representing compatibility and different application fields. All mentioned types are interchangeable.

What is the main difference to Varta V13GA (LR44)?

The main difference is in the cell chemistry. The V357 / V13GS (SR44) is a silver oxide battery, while the V13GA (LR44) is an alkaline battery. The silver oxide cell offers higher capacity, more stable voltage of 1.55 V and is the better choice for precision devices, whereas the LR44 alkaline cell is a cost-effective alternative for general use.

How should this button cell be disposed of?

Button cells must not be disposed of with household waste. Please take the empty battery to the designated collection points in retail stores or municipal recycling centres to ensure environmentally friendly recycling.
