Sonnenschein SOLAR S12/60 A lead-gel battery 12V 60Ah

The Sonnenschein S12/60 A is an absolutely maintenance-free lead-gel block battery, specially developed for the requirements of cyclical solar and off-grid use. As part of the globally proven Sonnenschein SOLAR series featuring Dryfit® gel technology, this battery provides unrivalled cycle life and reliability. With a nominal voltage of 12V and a nominal capacity of 60 Ah (C100), it is the ideal storage solution for small independent energy systems, signalling installations and mobile applications.

Highlights at a glance

• Superior Dryfit® gel technology: Absolutely maintenance-free throughout its service life, maximum reliability and leak-proof.
• High cycle life: Developed for daily, deep charge and discharge operation (approx. 800 cycles at 60% DoD).
• Compact design: High energy density in a compact and robust housing.
• Deep-discharge safe: Excellent recovery even after repeated deep discharges and robust against acid stratification.
• Low self-discharge: Perfect for seasonal use or periods of low sunlight.

Maximum supply reliability for independent systems

The Sonnenschein S12/60 A is the specialist for cyclical applications where the battery is charged and discharged daily. Its main fields of use are small off-grid solar systems for holiday homes, motorhomes, boats and yachts. It is also highly suitable for professional applications in telecommunications, traffic control systems, parking ticket machines or signalling installations that require an independent and maintenance-free power supply.

Proven Dryfit® gel technology

The Dryfit® gel technology, invented and perfected by Sonnenschein, immobilises the electrolyte in a thixotropic silica gel. This not only makes the battery absolutely leak-proof and maintenance-free, but also effectively prevents acid stratification – one of the main causes of premature battery failure in solar operation. The gel technology provides excellent cycle life and very low self-discharge.

Developed for longevity and reliability

The SOLAR series has been developed for maximum cost-effectiveness throughout its lifetime. The extremely high cycle life significantly reduces the need for costly and labour-intensive battery changes. The high manufacturing quality and use of high purity materials ensures constant performance and contributes to the high operational reliability of your independent energy supply.

FAQs about Sonnenschein S12/60 A lead-gel battery

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

The key advantage is the combination of absolute maintenance freedom, highest cycle life and extreme longevity. Compared to AGM batteries, gel batteries are often even more robust against deep discharges and provide very consistent performance over a long period of time.

What do the capacity specifications 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 since slower discharges over several days are common. C10 (discharge over 10 hours) is relevant for faster discharge.

What is the difference between this solar battery (S-series) and a standby battery (A-series)?

A solar battery (cyclic) like this is optimised for daily, deep discharge and recharge (high number of cycles). A standby battery (A-series) is designed for standby parallel operation (e.g., in UPS systems), is charged permanently and only rarely discharged (long design life in years).

How should this lead battery be disposed of?

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