Maximum supply security for critical infrastructure

The Sonnenschein A412/50 F10 is the specialist for standby parallel operation (standby use), where immediate and reliable transfer of energy in case of power failure is vital. Its main areas of application are uninterruptible power supplies (UPS) for computer and server systems, emergency and security lighting systems, fire and alarm systems as well as energy supply in hospitals and telecommunications systems.

Proven Dryfit® Gel Technology

The Dryfit® gel technology, invented and perfected by Sonnenschein, retains the electrolyte in a thixotropic silica gel. This not only makes the battery fully leak-proof and maintenance-free, but also ensures excellent cycle stability and a very low self-discharge rate. The internal gas recombination protects against capacity loss and ensures particularly safe and efficient operation, without the need for water refilling.

H2: Developed for longevity and reliability

The A400 series was designed for maximum cost-effectiveness throughout its entire service life. Its extremely long service life of 12 years or more significantly reduces the necessity for costly and tedious battery replacements in permanently installed systems. The high manufacturing quality and the usage of highly pure materials ensure consistent performance and contribute to the high operational safety of the overall facility.

FAQs about the Sonnenschein A412/50 F10 lead-gel battery

What is the main advantage of Dryfit® Gel Technology?

The decisive advantage lies in the combination of total maintenance freedom, highest cycle stability, and extreme longevity. Compared to AGM batteries, gel batteries are often even more resilient against deep discharges and provide a very consistent level of performance over a long time, making them the premium solution for critical standby applications.

What does the "Eurobat Long Life" classification mean?

Eurobat is the association of European battery manufacturers. The "Long Life" classification means that this battery is designed for an expected service life of 12 years or longer under defined standby conditions (typically 20°C ambient temperature and correct standby charging).

What is the difference between the F10 and the A connection?

Both are internally threaded connections. The F10 connection has an M10 thread, while the A connection (or G6) generally features a smaller M6 thread. The F10 connection is designed for applications with higher currents and larger cable cross-sections.

How should this lead battery be disposed of?

Lead batteries contain substances that are harmful to the environment and must not be disposed of in household waste. You can return your old battery free of charge to any retailer selling new batteries or to municipal recycling centres to ensure proper recycling.
