Sonnenschein A412/180 A lead gel battery 12V 180Ah

The Sonnenschein A412/180 A is an absolutely maintenance-free lead-gel block battery with very high capacity, developed for ultimate operational safety and extremely long service life in professional standby applications. As part of the globally proven A400-series with Dryfit® gel technology, this battery provides exceptional reliability. With a nominal voltage of 12V and a very high capacity of 180 Ah, it is the ideal energy source for fail-safe emergency power supply in large industrial plants, data centres and safety-critical systems.

Highlights at a glance

• Superior Dryfit® gel technology: Absolutely maintenance-free throughout its entire service life, maximum reliability and leakproof.
• Extreme longevity: Classified as “Long Life” (12 years and beyond) in accordance with Eurobat for maximum investment security.
• Very high capacity: 180 Ah for maximum bridging times during power failures.
• High cycle stability and deep-discharge protection: Offers excellent recovery even after deep discharges.
• Robust construction: Reinforced, impact-resistant housing for use under demanding conditions.

Maximum supply security for critical infrastructure

The Sonnenschein A412/180 A is the specialist for standby parallel operation, where immediate and reliable energy supply in the event of a power failure is essential. Its main areas of application are large uninterruptible power supplies (UPS), telecommunication and IT systems, emergency and safety lighting installations as well as energy supply in power plants, substations and railway installations. Wherever power outages would have serious consequences, this battery provides the necessary security.

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 leakproof 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—with no need to add water.

Engineered for longevity and reliability

The A400-series was developed for maximum economy throughout its entire service life. The extremely long service life of 12 years or more significantly reduces the need for costly and time-consuming battery replacements in permanently installed systems. The high manufacturing quality and the use of ultra-pure materials ensure constant performance and thus contribute to the high operational safety of the overall system.

FAQs about the Sonnenschein A412/180 A lead-gel battery

What is the main advantage of Dryfit® gel technology?

The key benefit is the combination of absolute maintenance freedom, highest cycle stability and extreme longevity. Compared to AGM batteries, gel batteries are often even more robust against deep discharges and provide very constant performance over a long period, 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 lifetime of 12 years or more under defined standby conditions (normally 20°C ambient temperature and proper float charging).

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

A standby battery like this one is optimised for standby parallel operation. It is kept permanently at a constant voltage (float charge) and only rarely releases energy. A starter battery is designed for short-term high currents. A solar battery (cycle battery) is optimised for daily deep discharge and recharge.

How must this lead-acid battery be disposed of?

Lead-acid batteries contain environmentally hazardous substances and must not be disposed of in domestic waste. You can return your old battery free of charge at any dealer selling new batteries or at municipal recycling centres to ensure proper recycling.
