Universal precision energy for demanding devices

The Varta V357 is a universally applicable power source for a wide range of devices that require powerful and reliable performance. It is ideal for wristwatches with energy-intensive additional functions such as lighting or alarm. It is also the perfect choice for calculators, digital calipers, laser pointers, toys, and various medical devices such as blood glucose meters.

Superior silver oxide technology

The silver oxide technology of the V357 offers a high energy density and a very stable voltage level. The "High Drain" (W) design is characterised by a lower internal resistance. This allows the battery to supply higher currents for short periods without the voltage dropping significantly, which ensures the reliable functioning of the connected devices.

Efficiency and safety for your devices

Varta batteries undergo the strictest quality controls to ensure consistently high performance and maximum safety. The high-quality processing and sealing of the V357 cell provides reliable protection against leakage, thus safeguarding your valuable devices from damage. Trust in tested quality.

FAQs about the Varta V357 watch battery

What does "High Drain" mean?

"High Drain" means that the battery is designed for devices with high energy requirements. It can supply high current for short periods of time, for example, for display lighting, a signal tone, or a measuring process. "Low Drain" batteries (with the suffix SW), on the other hand, are optimised for devices with very low, constant current consumption such as simple watches.

Can I replace an LR44 alkaline battery with this V357?

Yes, this is possible in any case and represents a significant upgrade. The V357 (SR44W) offers a longer service life and a much more stable voltage than an LR44 battery. This is especially beneficial in measuring devices and medical devices to ensure high accuracy.

What is the difference between a V357 (SR44W) and a V303 (SR44SW)?

Both are high-quality silver oxide batteries of the same size. However, the V357 is designed as a "High Drain" version for devices with higher current consumption (e.g. calculators). The V303 (SR44SW) is a "Low Drain" version specially optimised for the low, constant current requirement of simple wristwatches and provides maximum efficiency there.

How should this battery be disposed of?

Watch batteries must not be disposed of in household waste. Please take the empty battery to the designated collection points in retail stores or municipal recycling centres to ensure environmentally sound disposal.
