Highlights at a glance

• Superior Dryfit® Gel technology: Absolutely maintenance-free over the entire lifetime, 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: Provides excellent recovery even after deep discharges.
• Robust construction: Reinforced, impact-resistant housing for use under demanding conditions.
• Low self-discharge: High shelf life and always ready for use in an emergency.

Maximum security of supply for critical infrastructure

The Sonnenschein A406/165 A is the specialist for standby parallel operation (standby use), where immediate and reliable energy transfer is crucial in the event of a mains failure. 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 stations, substations and railway installations. 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 capacity loss and makes the operation particularly safe and efficient, without the need to top up with water.

Developed for longevity and reliability

The A400 series was developed for maximum cost-effectiveness over the entire service life. The extremely long service life of 12 years and more significantly reduces the need for expensive and laborious battery replacement in fixed installations. The high manufacturing quality and the use of high-purity materials ensure consistent performance and thus contribute to the high operational safety of the entire system.

FAQs about the Sonnenschein A406/165 A lead-gel battery

What is the main advantage of Dryfit® Gel technology?

The crucial advantage is the combination of absolute maintenance-free operation, 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 classification "Eurobat Long Life" 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 maintenance charging).

What is the difference between a standby battery and a starter or solar battery?

A standby battery like this one is optimised for standby parallel operation. It is permanently kept at a constant voltage (maintenance charge) and only rarely needs to supply energy. A starter battery is designed for short-term high currents. A solar battery (cycle battery) is optimised for daily, deep discharges and recharges.

How must 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 to any retailer selling new batteries or to municipal recycling centres free of charge to ensure proper disposal.
