Highlights at a glance

• Superior tubular plate technology: Offers the highest cycle stability and longevity in demanding solar and traction use.
• Dryfit® gel technology: Absolutely maintenance-free throughout its entire lifespan, highest reliability and leak-proof.
• Extremely high cycle life: Developed 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 autonomy.

Maximum supply security for off-grid systems

The Sonnenschein SB12/60 A is the specialist for large and critical cyclic applications. Its main areas of use are medium-sized off-grid solar systems for holiday homes, autonomous telecommunications stations, signalling systems and demanding marine applications. Wherever the battery is the only energy source and is deeply discharged daily, this battery offers 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, ensuring unrivalled longevity compared to standard grid plate batteries.

Developed for longevity and reliability

The SOLAR BLOCK series was developed for maximum economy over its entire lifespan. The extremely high cycle life significantly reduces the need for expensive and time-consuming battery replacement 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 SB12/60 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 cycle count (approx. 1200 cycles) and the toughest daily operation in large off-grid systems. The SOLAR (S) series (e.g. S12/85 A) uses grid plates and is also very cycle resistant (approx. 800 cycles), but the SB series offers even greater longevity in high-performance cyclic 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 discharges. This results in a significantly longer service life than for AGM or wet batteries in this application.

What do the C10 and C100 capacity values mean?

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

How should this lead-acid battery be disposed of?

Lead-acid batteries contain environmentally hazardous substances and must not be disposed of as household waste. You can return your old battery free of charge at any dealer who sells new batteries or at municipal recycling centres to ensure professional recycling.
