Optima is a US brand recognised by the six-cylinder shape of its batteries. At baterias.online its range covers cars, boats and motorhomes, and auxiliary uses.

Spiral-cell technology

Each cell contains long, thin lead plates wound into a tight spiral with glass-mat separators. The construction is extremely resistant to vibration, delivers strong bursts of current and allows mounting in many positions without risk of spills.

The three colours

• Red Top: starting batteries, for example RTC-4.2 or RTF-4.2.
• Yellow Top: dual-purpose for vehicles with winches, lighting or audio systems.
• Blue Top: marine batteries, such as BTDC-4.2 or BTDC-5.0, for starting and on-board power.

Choosing an Optima

Search Optima plus the code and look closely at the posts: some models have top posts, others side terminals, or both. Charge with an AGM-compatible charger and avoid leaving the battery deeply discharged.
