Highlights at a glance

• Superior Dryfit® gel technology: Absolutely maintenance-free throughout the entire service life, maximum reliability and leak-proof.
• Extreme longevity: Classified as "Long Life" (12 years and longer) according to Eurobat for maximum investment security.
• High cycle stability and deep discharge protection: Offers excellent recovery even after deep discharge.
• Robust construction: Reinforced, impact-resistant housing for use under demanding conditions.
• Low self-discharge: High storage capability and always ready for use in emergencies.

Maximum security of supply for critical infrastructure

The Sonnenschein A412/120 F10 is the specialist for standby parallel operation (standby use), where immediate and reliable power transfer is crucial during a power outage. Its main areas of application are uninterruptible power supplies (UPS), telecommunication and IT systems, emergency and safety lighting systems, as well as power supply in power stations, substations, and railway systems. Wherever a power failure would have serious consequences, this battery provides the necessary reliability.

Proven Dryfit® gel technology

The Dryfit® gel technology invented and perfected by Sonnenschein binds the electrolyte in a thixotropic silica gel. This not only makes the battery 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 the operation particularly safe and efficient without the need to refill water.

Developed for longevity and reliability

The A400 series has been developed for maximum cost-effectiveness throughout its service life. The extremely long service life of 12 years and more significantly reduces the need for expensive and time-consuming battery changes 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 overall system.

FAQs about the Sonnenschein A412/120 F10 lead-gel battery

What is the main advantage of Dryfit® gel technology?

The decisive advantage is the combination of absolute maintenance-free operation, maximum cycle stability and extreme longevity. Compared to AGM batteries, gel batteries are often even more robust against deep discharge and offer very consistent performance over a long period, making them a 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 trickle charge).

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 (trickle charge) and rarely needs to deliver energy. A starter battery is designed for short periods of high current. A solar battery (cycle battery) is optimised for daily deep discharges and recharging.

How should this lead-acid battery be disposed of?

Lead-acid batteries contain environmentally harmful substances and must not be disposed of with 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.
