    Marine electrical systems place unique demands on battery technology, requiring reliable cranking power alongside resilience to vibration, moisture and deep discharge cycles. The Optima Blue Top 8006-252 is a 12V 50Ah AGM starter battery engineered specifically for boats, personal watercraft and recreational vehicles where high-draw electronics and trolling motors create conditions that defeat conventional flooded batteries. Optima's proprietary Spiral cell AGM construction winds pure lead plates into a tight cylindrical cell, eliminating free electrolyte and producing a battery that is both spill-proof and highly resistant to vibration damage. The absorbed glass mat design maintains close plate separation under load, sustaining the 815A cold cranking output that defines the 8006-252's starting capability even after repeated deep-discharge events. The 8006-252 measures 254mm x- 175mm - 200mm (L x- W x- H) and weighs 18.4kg. It is fitted with dual SAE post and stud terminals (DT terminal type) with standard polarity (positive right, configuration code 1) and uses a B00 hold-down system. No direct cross-reference codes are listed; fitment should be confirmed against vehicle manufacturer specifications.
