FAQs about the VARTA Lithium Battery CR2025

What does the designation CR2025 mean?

The designation gives information about the properties and the size of the cell. "C" stands for lithium chemistry, "R" for the round shape. The numbers "2025" denote the dimensions: 20.0 mm in diameter and 2.5 mm in height.

Is this battery rechargeable?

No. This is a primary lithium battery. Under no circumstances should it be attempted to recharge it. Charging attempts are extremely dangerous and may result in fire or explosion.

What is the advantage over alkaline or silver oxide button cells?

The main advantage is the high voltage of 3 volts in a single cell, while alkaline and silver oxide cells provide only 1.5 or 1.55 volts. In addition, lithium cells offer a significantly longer shelf life and a wider temperature range.

How must this battery be disposed of?

Batteries must not be disposed of in household waste. Please dispose of the empty battery at the designated collection points in stores or municipal recycling centres for environmentally friendly disposal.
