Single-use battery Varta CR9V
The Varta CR9V is a single-use 9V lithium battery in a prismatic form factor, designed for reliable long-term operation in devices such as smoke detectors and other low-drain or intermittent-use electronics. It measures approximately 26.5 mm (width) × 17.5 mm (depth) × 49.2 mm (height) and weighs about 36–41 g, providing a compact, lightweight power source with stable voltage output.
This Varta 9V lithium battery contains no mercury, lead or cadmium and offers significantly longer runtime than conventional 9V alkaline or carbon-zinc cells. It can perform reliably at extreme temperatures from -20°C to +60°C and has a shelf life of up to 10 years without leakage. Compared with typical competitor cells, it provides up to 40% better performance and can last up to 5 times longer than standard 9V alkaline batteries.
Install the Varta CR9V battery according to the device manufacturer’s instructions, observing correct polarity when inserting the battery into the 9V compartment. For smoke detectors, replace the battery as recommended by the alarm manufacturer or when the low-battery indication appears. Store unused batteries in a cool, dry place and avoid short-circuiting the terminals during handling.
Use this Varta 9V lithium battery as the primary power source for smoke detectors and safety-critical devices where long shelf life, stable performance in a wide temperature range, and minimal maintenance are required. Do not attempt to recharge single-use lithium batteries; dispose of them in accordance with local regulations.
