FAQs about the Sonnenschein A506/6.5 S lead-acid battery

What is the maximum load capacity?

The battery can be permanently loaded up to approx. 80 A and delivers up to 300 A discharge current for short periods.

What are the advantages of the dryfit technology?

It offers absolute maintenance-free operation, very low self-discharge, high operational safety and a long service life.

What is the capacity and service life of this battery?

The battery has a nominal capacity of 6.5 Ah (C20) and, according to the manufacturer, is designed for a service life (Design Life) of 10 to 12 years under normal conditions (e.g. 20 °C).

Is the battery maintenance-free and how does it behave in the event of deep discharge?

Yes, the battery is maintenance-free throughout its entire service life, i.e. it does not have to be topped up with water. It is designed to be protected against deep discharge and uses gel dryfit technology with internal gas recombination to minimise gas formation.

How long can the battery be stored before recharging is necessary?

Thanks to very low self-discharge, the battery can be stored for up to 2 years at 20 °C without recharging, without risking major loss of capacity.
