Car battery OPTIMA RTR-4.2 12V 50Ah 815A

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 RED TOP

Use OPTIMA's SpiralCell technology: six 99.99% pure lead cells wound in a spiral and sealed in AGM. That construction gives it a very high cranking current, vibration resistance up to fifteen times higher than a conventional battery and the ability to be mounted in almost any position without spilling.

The OPTIMA RED TOP is a pure starting battery: delivers the maximum cranking current to start the engine powerfully, even in cold or with the battery slightly discharged. It is recognized by its red cover.
