About this battery
OPTIMA YellowTop is a dual-purpose (deep-cycle + starting) battery — strong engine starting plus the ability to be drained flat and recharged over and over. Ideal for heavy electrical accessories (audio, winch, lighting), start-stop use, or vehicles that sit unused for long periods. Its AGM SpiralCell construction makes it maintenance-free, spill-proof and vibration-resistant.

Key terms

• CCA (Cold Cranking Amps) — cold-start power; higher means a stronger start in the cold
• Ah — capacity / energy reserve
• L+ / R+ — terminal polarity (which side the positive post is on); important for correct fitment
