Sonnenschein A412/100 A lead gel battery 12V 100Ah

The Sonnenschein A412/100 A is an absolutely maintenance-free lead-gel block battery that has been developed to meet the highest demands for operational reliability and an extremely long service life in professional standby applications. As part of the globally proven A400 series with Dryfit® gel technology, this battery offers exceptional reliability. With a nominal voltage of 12V and a capacity of 100 Ah, it is the ideal energy source for fail-safe emergency power supplies in telecommunications, industrial plants and safety-relevant systems.

Highlights at a glance

• Superior Dryfit® gel technology: Absolutely maintenance-free over 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: Provides excellent recovery even after deep discharges.
• Robust construction: Reinforced, impact-resistant housing for use in demanding conditions.
• Low self-discharge: High shelf life and always ready for use in an emergency.

Maximum security of supply for critical infrastructure

The Sonnenschein A412/100 A is the specialist for standby parallel operation (standby use), where an immediate and reliable power supply is crucial in the event of a mains failure. Its main areas of application are uninterruptible power supplies (UPS), telecommunications 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 security.

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 operation particularly safe and efficient without the need to top up with water.

Developed for longevity and reliability

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

Battery features

FAQs about the Sonnenschein A412/100 A lead-gel battery

What is the main advantage of Dryfit® Gel technology?

The decisive advantage is the combination of absolute freedom from maintenance, maximum cycle stability and extreme longevity. Compared to AGM batteries, gel batteries are often even more robust against deep discharges and offer very constant 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 trickle charging).

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

A standby battery such as this one is optimised for standby parallel operation. It is permanently kept at a constant voltage (trickle charge) and only rarely has to release 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 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 to any retailer that sells new batteries or to municipal recycling centres free of charge to ensure that it is recycled properly.
