Sonnenschein A612/100 A Lead-gel battery 12V 100A

The Sonnenschein A612/100 A is an absolutely maintenance-free lead-gel block battery developed for high operational reliability and long service life in professional standby and light cyclic applications. As part of the globally proven A600 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, signalling systems, and medical technology.

Highlights at a glance

• Superior Dryfit® gel technology: Absolutely maintenance-free throughout its life, maximum reliability, and leak-proof.
• High reliability: Classified as "General Purpose" according to Eurobat for a long service life of 6 to 9 years.
• High cycle stability: Offers good cycle stability and excellent recovery even after deep discharges.
• Robust construction: Reinforced, impact-resistant housing for use under 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 A612/100 A is a versatile specialist for standby-parallel operation (standby use) and light traction applications. Its main areas of application are uninterruptible power supplies (UPS), telecommunications and IT systems, emergency and safety lighting systems as well as the power supply in hospitals, railway installations, and in marine technology.

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 provides excellent cycle stability and very low self-discharge. The internal gas recombination protects against loss of capacity and makes operation particularly safe and efficient, without the need to top up with water.

Developed for longevity and reliability

The A600 series was developed for maximum cost-effectiveness over the entire service life. The long service life of up to 9 years reduces the necessity of expensive 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 overall system's high operational reliability.

FAQs about the Sonnenschein A612/100 A lead-gel battery

What is the main advantage of Dryfit® gel technology?

The key advantage is the combination of absolute maintenance freedom, high 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.

What does the "Eurobat General Purpose" classification mean?

Eurobat is the association of European battery manufacturers. The "General Purpose" classification means that this battery is designed for an expected lifespan of 6 to 9 years under defined standby conditions (mostly 20°C ambient temperature and correct float 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 (float charge) and only rarely needs to deliver energy. A starter battery is designed for short-term, high currents. A solar battery (pure cycle battery) is optimised for daily, deep discharging and recharging.

How should this lead battery be disposed of?

Lead batteries contain environmentally hazardous substances and must not be disposed of with household waste. You can return your old battery free of charge to any retailer that sells new batteries or at municipal recycling centres to ensure proper disposal.
