FAQs about the VARTA lithium battery CR2032

What does the designation CR2032 mean?

The designation gives information about the properties and size of the cell. "C" stands for the lithium chemistry, "R" for the round design. The numbers "2032" stand for the dimensions: 20.0 mm in diameter and 3.2 mm in height.

Is this battery rechargeable?

No. This is a primary lithium battery. Under no circumstances should you attempt to recharge it. Attempting to charge is extremely dangerous and can lead to 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 one cell, while alkaline and silver oxide cells only provide 1.5 or 1.55 volts. In addition, lithium cells offer a significantly longer shelf life, a higher capacity and a broader operating temperature range.

How should this battery be disposed of?

Batteries must not be disposed of in household waste. Please return the empty battery to the designated collection points in stores or municipal recycling centres to ensure environmentally responsible disposal.
