The SOLAR (S) series (e.g. S12/85 A) uses grid plates and is also very cycle-resistant (approx. 800 cycles), but the SB series offers even higher durability in high-performance cyclic operation.What is the main advantage of Dryfit® gel technology in solar operation?In cyclic solar operation, avoiding acid stratification is crucial. In gel batteries, the electrolyte is bound, preventing stratification and making the battery more resistant to deep discharges. This results in a significantly longer life than with AGM or wet batteries in this application.What do the capacity specifications 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, as slow discharges over several days are more common here. C10 (discharge over 10 hours) is relevant for faster discharging.How should this lead battery be disposed of?Lead batteries contain environmentally harmful substances and must not be disposed of in household waste. You can return your old battery free of charge to any retailer selling new batteries or to local recycling facilities to ensure proper recycling.
