ACDelco Marine RV Deep Cycle Battery

ACDelco stands for quality. Get the performance you need with ACDelco products. ACDelco Deep Cycle RV and Marine Batteries’ maintenance-free deep cycle design allows batteries to provide long streams of power for extended periods of time. They have heavier, thicker plates that can withstand the potential damage of continual deep discharging and recharging. Both positive and negative grids are built with lead-calcium alloy to maximize corrosion resistance, increase cycle life and reduce water consumption for battery durability. ACDelco Deep Cycle RV and Marine Batteries also include quick-glance charge monitoring for worry free use. ACDelco products are developed to exceed your performance expectations and deliver the durability you expect.


• Thermoplastic reinforced separators increase protection against plate shorting for improved durability.
• Built-in “Green Eye” hydrometer on certain deep cycle batteries, for quick-glance state of charge monitoring.
• The extreme bond of our reformulated negative paste resists flaking to improve overall performance and increase life.
• Both positive and negative grids are lead-calcium alloy to maximize corrosion resistance, increase cycle life, and reduce water consumption for battery durability.
• Framed positive grid is optimized for conductivity, vibration resistance, and offers superior cycling performance.
• 100% pressure tested to reduce the possibility of future leaks.
• Maintenance free – no water required.
• Strong and comfortable handle for easy portability.


• Recharge battery after each use.
• Use a taper type charger set at 15.0 volts. Taper chargers help avoid overcharge by reducing the charge rate as the battery nears full charge. Follow instructions provided with the charger.
• Determine the charging time that will be required. Check the built-in indicator and charge the battery for at least the number of hours shown in the charging table (located in “Charging Instructions” section). If the green ball is not visible in the indicator after charging, tap lightly on top to dislodge trapped air bubbles that might keep the green ball from floating into view. For the most accurate results allow the battery to rest for 12 hours then measure battery voltage, 12.8 volts is fully charged.
• NOTE: A more definite charging time can be set if an accurate voltmeter is available for reading open circuit voltage.
• DO NOT leave a battery connected to a battery charger after the battery is fully charged. Inspect battery every 2 hours when charging.
• Keep battery in a cool place when storing for long periods (make sure battery is fully charged – a discharged battery’s electrolyte can freeze).
• Keep battery terminals clean and free of corrosion. To remove corrosion from terminals, use a terminal brush.
• For maximum battery life where electrical requirements are high, separate starting and running batteries are recommended.


Q: Can I determine what the Hours of Usable Power (H.U.P.) is for this battery?
A: Yes. By determining the ampere draw of each for the accessories in use, Hours of Usable Power (H.U.P.) can be determined. The following information will give the data necessary to be a specialist when talking "marine" and continuous use. Over time H.U.P. will decrease as the battery ages, H.U.P. will also be reduced if the battery does not start at 100% charge. With the ACDelco built in Hydrometer, a user can see the state-of-charge (SOC) but still cannot plan for the hours of useable power.

Q: Can I tell how many Marine Cranking Amps this battery has?
A: Yes. MCA refers to Marine Cranking Amps, their values are on the top label of the ACDelco Voyager and Voyager II Batteries. MCA equals CA.

Q: Does this RV and marine battery perform well in cold weather?
A: ACDelco supplies Cold Cranking Amp (CCA) information on the label of the battery. This information is valuable if the use is for something other than marine cranking applications.

Q: Can I use the "Green Eye" hydrometer to determine the batteries State-of-Charge?
A: Yes, the Hydrometer (EYE, Green Eye) gives the State-of-Charge (SOC) on one cell and if the eye is ‘Green’ this means that the battery’s State-of-Charge should be greater than 65%. If the eye is ‘black’ the battery requires recharging. If the eye is clear, the acid level is low and the battery must be replaced immediately. Do not recharge.
