Sonnenschein SOLAR BLOCK SB12/100 A lead-gel battery 12V 100Ah

The Sonnenschein SB12/100 A is an absolutely maintenance-free, premium-class lead-gel block battery developed for the most demanding cyclic applications in professional solar systems. As part of the SOLAR BLOCK series, it combines proven Dryfit® gel technology with an extremely robust tubular plate construction. With a nominal voltage of 12V and a capacity of 100 Ah (C100), it offers the highest cycle life and reliability for self-sufficient energy systems.

Highlights at a glance

• Superior tubular plate technology: Offers the highest cycle life and durability in demanding solar and traction use.
• Dryfit® gel technology: Absolutely maintenance-free throughout its entire service life, with maximum reliability and leak-proof design.
• Extremely long cycle life: Designed for thousands of charge and discharge cycles (approx. 1200 cycles at 60% DoD).
• Deep discharge proof: Excellent recovery even after repeated deep discharges and absolutely robust against acid stratification.
• Low self-discharge: Perfect for seasonal use and long periods of self-sufficiency.

Maximum security of supply for self-sufficient systems

The Sonnenschein SB12/100 A is the specialist for large and critical cyclical applications. Its main areas of use are medium- to large-scale off-grid solar systems, self-sufficient telecommunications stations, signalling systems, and demanding marine applications. Wherever the battery is the only energy source and is deeply discharged on a daily basis, this battery provides maximum service life and reliability.

Proven Dryfit® gel and tubular plate technology

The combination of Dryfit® gel and tubular plates (positively armoured) is the key to the extreme robustness of this battery. The gel binds the electrolyte, prevents acid stratification, and makes the battery maintenance-free. The tubular plate construction protects the active mass from decay during deep discharge cycles and ensures unrivalled durability compared to standard grid plate batteries.

Developed for durability and reliability

The SOLAR BLOCK series was developed for maximum cost-effectiveness throughout its entire service life. The extremely long cycle life significantly reduces the need for costly and time-consuming battery replacements and lowers the system's total cost of ownership (TCO). The high manufacturing quality ensures consistent performance and maximum operational safety.

FAQs about the Sonnenschein SB12/100 A lead-gel battery

What is the difference between this SOLAR BLOCK (SB) and the SOLAR (S) series?

The SOLAR BLOCK (SB) series (this model) uses a tubular plate construction. It is designed for an extremely high number of cycles and the toughest daily use in large off-grid systems. The SOLAR (S) series (e.g. S12/130 A) uses grid plates and is also very cycle-resistant, but the SB series offers an even longer lifespan in high-performance cycling operation.

What is the main advantage of Dryfit® gel technology in solar operation?

In cyclic solar operation, avoiding acid stratification is crucial. In gel batteries the electrolyte is bound, which prevents stratification and makes the battery more resistant to deep discharge. This results in a much longer service life compared to AGM or wet batteries in this application.

What do the capacity ratings C10 and C100 mean?

The capacity of a battery depends on how quickly it is discharged. The C-rate specifies the discharge current. C100 (discharge over 100 hours) is the standard for solar applications, as slow discharges over several days are more common here. C10 (discharge over 10 hours) is relevant for a faster discharge.

How should this lead battery be disposed of?

Lead batteries contain environmentally harmful substances and must not be disposed of in household waste. You can return your old battery free of charge to any dealer who sells new batteries or to municipal recycling centres to ensure proper disposal.
