Optima 34M BlueTop is designed as a starting battery for people
who need a sure-starting, strong cranking, and maintenance free
power source for their boat or RV, even in harsh conditions. The
unique SpiralCell design provides a strong and clean power source,
ensuring the safety of you, your family and the environment. The
higher reserve capacity gives you a longer shelf-life to give you
the power when you need it, where you need it.
