Sonnenschein A512/140 A lead gel battery 12V 140Ah

The Sonnenschein A512/140 A is an absolutely maintenance-free lead-gel block battery that has been developed for the highest demands on operational safety and an extremely long service life in professional standby applications. As part of the globally proven A500 series with Dryfit® gel technology, this battery offers exceptional reliability. With a nominal voltage of 12V and a high capacity of 140 Ah, it is the ideal energy source for fail-safe emergency power supplies in telecommunications, in industrial installations, and in safety-relevant systems.

Highlights at a glance

• Superior Dryfit® gel technology: Absolutely maintenance-free throughout the entire service life, maximum reliability and leak-proof.
• Extreme longevity: Classified as "Long Life" (12 years and longer) according to Eurobat for maximum investment security.
• High cycle stability and deep discharge protection: Offers excellent recovery even after deep discharges.
• Robust construction: Reinforced, impact-resistant housing for use in demanding conditions.
• Low self-discharge: High shelf life and always ready for use in an emergency.

Maximum supply security for critical infrastructure

The Sonnenschein A512/140 A is the specialist for standby parallel operation (standby use), where immediate and reliable power takeover is crucial in the event of a power outage. Its main areas of application are uninterruptible power supplies (UPS), telecommunications and IT systems, emergency and safety lighting systems, as well as power supply in power plants, substations, and railway facilities. Wherever a power failure would have serious consequences, this battery provides the necessary security.

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

Developed for longevity and reliability

The A500 series was developed for maximum economy throughout the entire service life. The extremely long service life of 12 years or more considerably reduces the need for costly and complex battery replacements in permanently installed systems. The high manufacturing quality and the use of highly pure materials ensure consistent performance and thus contribute to the high operational reliability of the overall system.

FAQs about the Sonnenschein A512/140 A lead-gel battery

What is the main advantage of Dryfit® gel technology?

The crucial advantage is the combination of absolute freedom from maintenance, highest 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, making them the premium solution for critical standby applications.

What does the "Eurobat Long Life" classification mean?

Eurobat is the association of European battery manufacturers. The "Long Life" classification means that this battery is designed for an expected service life of 12 years or more under defined standby conditions (usually 20°C ambient temperature and correct trickle 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 (trickle charge) and only rarely needs to release energy. A starter battery is designed for short-term, high currents. A solar battery (cycle battery) is optimised for daily deep discharge and recharging.

How should this lead-acid battery be disposed of?

Lead-acid batteries contain substances that are harmful to the environment and must not be disposed of in household waste. You can return your old battery free of charge to any retailer who sells new batteries or to municipal recycling centres to ensure proper recycling.
