Highlights at a glance

• Superior Dryfit® gel technology: Absolutely maintenance-free throughout the entire service life, maximum reliability, and leak-proof.
• Extremely high cycle stability: Designed for daily, deep charging and discharging in solar installations.
• High capacity: 130 Ah (C100) for reliable and long-lasting energy buffering.
• Deep discharge resistant: Excellent recovery even after repeated deep discharges and robust against acid stratification.
• Low self-discharge: Perfect for seasonal use or periods of low solar radiation.

Maximum supply security for autonomous systems

The Sonnenschein S12/130 A is the specialist for cyclical applications where the battery is charged and discharged daily. Its main areas of use are off-grid solar systems for holiday homes, mountain huts, motorhomes, boats and yachts. It is also excellent for professional applications in telecommunications or signalling systems that require autonomous and maintenance-free power supply.

Proven Dryfit® gel technology

The Dryfit® gel technology invented and perfected by Sonnenschein binds the electrolyte in a thixotropic silica gel. This makes the battery not only 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 guarantees excellent cycle stability and a very low self-discharge rate.

Designed for durability and reliability

The SOLAR series was developed for maximum economic efficiency over the entire service life. The extremely high cycle lifetime significantly reduces the need for costly and time-consuming battery replacements. High manufacturing quality and the use of high-purity materials ensure consistent performance and thus contribute to the high operational reliability of your autonomous energy supply.

FAQs about the Sonnenschein S12/130 A lead-gel battery

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

In cyclical 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 with AGM or wet batteries in this application.

What do the capacity indicators C10 and C100 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 more common here. C10 (discharge over 10 hours) is relevant with faster discharging.

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

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

How should this lead-acid battery be disposed of?

Lead-acid 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 who sells new batteries or to municipal recycling depots to ensure proper recycling.
