Optima Yellow Top D31A - 12 Volt - 75Ah - 900CCA - Spiral Cell AGM Deep Cycle Battery (D31A)
High power, dual purpose engine start and deep cycle
2 Year Warranty
The YELLOWTOP high-performance AGM battery is one of the few true dual-purpose automotive batteries available. With premium cranking power and impressive cycling capability, this heavy-duty battery is also perfect for modern accessory-loaded vehicles. Low internal resistance also provides more consistent power output and faster recharges.
Features:
| Repetitive reserve capacity | Optima batteries have the ability to withstand signficantly more discharge/recharge cycles with lower degradation of overall capacity over time than other AGM battery alternatives. This means more running time, faster recharge, and up to twice the life of traditional Marine and RV batteries. |
| Massive starting current | Optima spiral cells have more surface area per cell than any other lead acid battery design and are linked together with huge heavy duty cast-on bus bars. This allows Optima batteries to deliver a higher level of power to the starter in the critical first 10 seconds of the vehicle starting cycle. |
| 15 times more vibration resistance | Optima’s patented Spiral Cell construction delivers more than 15 times the vibration resistance of a traditional lead acid battery. This all but eliminates the possibility of damage from vibration, which is a leading cause of battery failure. |
| Safety, on any angle | Traditional batteries will spill acid after a rotation of 45-degrees. Optima batteries can be rotated up to 180-degrees with no acid spill. |
| Corrosion free terminals | Optima’s unique approach to cell construction and fully spill proof design ensures zero maintenance is required and that corrosion does not form on the positive and negative terminals. |
| High purity lead grids & AGM separators | Glass separator hold the electrolyte like a sponge immobilising the internal components of the battery. This enables Optima batteries to deliver more power for longer, and over more cycles, than other AGM type alternatives. |
| Resealable pressure relief valves | Advanced pressure relief valves allow the battery to vent under extreme conditions, but remain sealed under general use. This resealable valve design dramatically extends the service life of the battery while minimising the risk of explosion during severe overcharge or discharge, and under other adverse conditions. |
