About this battery
OPTIMA BlueTop is the marine / RV version, adding threaded marine terminals alongside the standard posts. Depending on model it works as a starting battery (like RedTop) or a dual-purpose deep-cycle battery (like YellowTop) — suited to boats, trolling motors and campers. Its AGM SpiralCell construction makes it maintenance-free, spill-proof and vibration-resistant.

Key terms
