ACDelco Automotive AGM Battery

ACDelco stands for quality. Get the performance you need with ACDelco products. ACDelco Automotive AGM Batteries have high cycling capabilities, are remarkably charge-receptive, and are necessary for ‘start/stop’ vehicle applications. The Absorbed Glass Mat design is 100% leak and spill proof because the electrolyte is permanently held in the glass mat separator instead of free flowing within each cell. Oxygen recombination reduces water loss and reassures maintenance-free performance. ACDelco Automotive AGM Batteries have longer life expectancy in traditional vehicle applications, due to a maintained pressure on the plates which significantly reduces the amount of active mass lost from the grid. ACDelco products are developed to exceed your performance expectations and deliver the durability you expect.


• Maintenance-free Absorbed Glass Mat (AGM) technology - no water required, no spills, no leaks, and no maintenance.
• Valve regulated-gas recombinant technology, can provide up to 3-times the cycle life of conventional auto batteries in traditional vehicle applications.
• Calcium positive and negative, full-frame power path grids provide higher cranking amps and lower self-discharge rates for off season storage (compared with antimony and calcium flooded technology).
• Leak-proof pressurized valve system is engineered for safety and long life. Prevents dry-out and acid damage to the terminals.
• High density plate oxide provides for maximum power-per-pound and dependable ‘high cycling’ service.
• Heavy top lead and large through-partition connections increases power output, durability, vibration resistance and auto battery life.


• 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: How can I tell how much reserve capacity my battery has?
A: This should be on the label right under the CCA rating of the battery.

Q: Does this battery perform well in cold weather?
A: It is important to have the right battery for your vehicle. Refer to OEM specifications in your Owner's manual or an OEM driven supplier such as ACDelco.

Q: How long does this battery last without losing its charge?
A: All batteries need to be maintained. Parasitic drains in a vehicle can deplete a battery in 2-4 weeks. To be safe, vehicles should be started once a week or once every other week and idled for 5 minutes to ensure that the battery retains a reasonable state of charge.

Q: What is the difference between an Accessible Maintenance-Free Battery and a Filler Cap Battery?
A: Batteries that are Accessible Maintenance Free or Sealed Maintenance Free have a Calcium Additive in the plate material inside the battery that helps to prevent the gassing off of electrolyte. These types of batteries should never need to have water added. Vent caps on these batteries should not be removed at any time as this breaks the seal and could allow seepage or water loss. Low electrolyte in these batteries is an indication of overcharging. Filler Cap batteries have an additive in them that requires the checking and refilling of the battery with distilled water.

Q: If my car has a "start-stop" feature, does this affect what type of battery my car has?
A: In the case of GM vehicles, AGM batteries are required for start-stop vehicles. Use of a flooded battery will result in the life only being about 4-6 months. Most other vehicle manufacturers are using AGM for these vehicles as well.
