Ansmann Lithium Battery for Smoke Detector, 9V Block

• Lithium chemistry: Delivers dependable long-term power and a low self-discharge rate, making it well suited to smoke detectors that must remain ready over extended standby periods.
• 9V Block / 6LR61 format: Fits devices designed for the common 9V block battery size, so it is a straightforward replacement for compatible smoke alarms and other electronics.
• 1100.00 mAh capacity: Supports long service intervals in low-drain applications, reducing the need for frequent battery changes in safety devices.
• - 40 / + 60 °C working range: Maintains operation across a wide temperature span, which is useful for detectors installed in colder utility spaces or warmer indoor environments.
• Non-rechargeable design: Provides a simple install-and-use power source for devices intended for primary batteries, without the maintenance routine of charging cycles.

About the Ansmann Accessories Series

Ansmann Accessories covers the brand’s everyday power and support products for common electronic devices. Within the wider ANSMANN range, this series sits around practical battery formats and related essentials intended for household use, portable electronics and routine replacement needs. The family includes familiar sizes used in items such as remote controls, flashlights and other battery-powered equipment, with an emphasis on dependable fit, stable output and straightforward compatibility.

Rather than focusing on one specialist application, the Accessories series is built around broad usability. It spans multiple battery formats, including 9 V versions, so users can match the right cell size to the device without moving outside the same product family. In practice, that makes the series relevant for safety devices, domestic electronics and general-purpose equipment where consistent power delivery matters more than advanced charging features. The result is a range defined by practical replacement power, familiar sizing and a clear focus on reliable day-to-day use.

About the Ansmann Lithium Battery for Smoke Detector, 9V Block

The Ansmann Lithium Battery for Smoke Detector, 9V Block is a primary lithium battery designed for applications where long standby performance and dependable readiness matter more than repeated high-drain cycling. Its 9V Block / 6LR61 format makes it suitable for compatible smoke detectors, where a stable, long-lasting power source helps reduce maintenance intervals and supports continuous operation between battery changes.

With a stated capacity of 1100.00 mAh, this battery is particularly well matched to low-drain safety devices that remain on watch around the clock. Lithium chemistry also brings practical advantages in storage and service life, helping the battery retain useful energy over time instead of losing charge quickly while sitting installed or in reserve. For smoke alarms, that matters because reliability during long idle periods is often more important than short bursts of peak output.

The battery also works across a wide - 40 / + 60 °C operating range, which adds flexibility for detectors placed in cooler entry spaces, loft areas or other environments that may see larger temperature swings than a typical living room. Because it is non-rechargeable, it is intended as a direct fit-and-forget power source for devices built around disposable 9V batteries. That keeps installation simple and avoids the charging routines associated with rechargeable cells.

About Ansmann

Ansmann was founded by Edgar Ansmann in 1991 in Assamstadt, Germany. The company focuses on battery, charging, drive-system and lighting technology, with a product range that covers both consumer and technical applications. In the consumer segment, ANSMANN is well known for rechargeable batteries and chargers in widely used formats such as AA and AAA, giving it a strong foundation in portable power products.

Its battery expertise also includes proprietary developments such as maxE technology for low self-discharge NiMH rechargeable batteries. In 2012, the company opened its own UN test center, underlining a serious approach to battery testing and transport-related compliance. For products such as household batteries and power accessories, that background is relevant because it reflects long-standing specialization in safe, practical energy solutions rather than a broad electronics portfolio.
