The brand
OPTIMA: the spiral cell battery that is unlike any other
OPTIMA does not manufacture flat-plate batteries: each cell is a spiral roll of two sheets of 99.99% pure lead. That SpiralCell architecture is what gives it its recognizable six-cylinder shape and explains its durability: it can withstand up to fifteen times more vibration than a conventional battery.
When sealed and with the electrolyte absorbed in glass fiber (AGM), it does not spill, does not require maintenance, and can be mounted in almost any position. It belongs to the Clarios group, the world's largest manufacturer of starting batteries, just like VARTA.
The range
OPTIMA BLUE TOP
Apply the pure lead SpiralCell technology to the marine environment: sealed and waterproof, resists waves, vibration, and deep discharges from onboard consumption. It does not leak even when the boat tilts and requires no maintenance.
The OPTIMA BLUE TOP is the spiral cell marine battery: starts the boat engine and powers the onboard services. It is recognized by its blue cover and usually has double terminals.
