Maximum supply security for critical infrastructure

The Sonnenschein A412/50 G6 is the specialist for standby parallel operation, where immediate and reliable energy transfer is crucial in the event of a mains failure. Its main areas of application are uninterruptible power supplies (UPS) for computer and server systems, emergency and safety lighting systems, fire alarm and security systems, as well as power supply in hospitals and telecommunications systems.

Proven Dryfit® Gel technology

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

Developed for longevity and reliability

The A400 series was developed for maximum efficiency over the entire service life. The extremely long service life of 12 years and more significantly reduces the necessity for costly and extensive battery replacements in fixed installations. The high manufacturing quality and the use of highly pure materials ensure consistent performance and thus contribute to the high operational reliability of the entire system.

FAQs about the Sonnenschein A412/50 G6 lead-gel battery

What is the main advantage of Dryfit® Gel technology?

The decisive advantage is the combination of absolute maintenance-free operation, highest cycle stability, and extreme longevity. Compared to AGM batteries, gel batteries are often even more robust against deep discharges and offer very consistent performance over a long period of time, making them the premium solution for critical standby applications.

What does the classification "Eurobat Long Life" 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 more under defined standby conditions (usually 20°C ambient temperature and correct float charging).

What is the difference between a standby battery and a starter or solar battery?

A standby battery like this is optimised for standby parallel operation. It is permanently maintained at a constant voltage (float charge) and only rarely needs to deliver energy. A starter battery is designed for short-term, high currents. A solar battery (cycle battery) is optimised for daily, deep discharging and recharging.

How must this lead-acid battery be disposed of?

Lead-acid batteries contain environmentally hazardous substances 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 disposal.
