SLA Batteries

• In terms of technology and performance, SLA batteries are the successor to lead-acid batteries
• Without liquid acid, therefore 100 % maintenance-free and without corrosive vapours!
• Leak-proof thanks to SLA technology, can also be installed horizontally
• Delivered pre-charged - please charge once before first installation
• After lead-acid batteries, SLA batteries are the most insensitive batteries to overvoltage and therefore the first choice for our classic cars with technically simple (in practice imprecise) charging electrics
