These batteries are marine grade, sealed and maintenance free. Manufacturer estimates a 5 to 10 year life cycle. With a daily discharge of 50% the manufacturer projects 3600 cycles which give you just shy of 10 years of operational life.

The Firefly MicrocellTM Carbon Foam (MCF) batteries is the technology behind this extraordinary performance. It easily recovers from being stored in a partially discharge state and they are manufactured in the USA.

Currently available only in a group 31 size.
