FAQs about the VARTA lithium battery CR2450

What does the designation CR2450 mean?

The designation provides information about the features and size of the cell. "C" stands for lithium chemistry, "R" for the round shape. The numbers "2450" correspond to the dimensions: 24.5 mm in diameter and 5.0 mm in height.

Is this battery rechargeable?

No. This is a lithium primary battery. It must never be recharged under any circumstances. Attempting to charge it is extremely dangerous and may cause fire or explosion.

What is the advantage over smaller coin cells such as the CR2032?

The main advantage of the CR2450 is its nearly three times higher capacity. It contains significantly more energy and therefore enables much longer operation in devices with higher energy consumption or in cases where particularly long maintenance intervals of several years are desired.

How should this battery be disposed of?

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