About this product

ACDelco Silver Vehicle Batteries are a quality, high value alternative for General Motors vehicles as well as most makes and models and are backed by General Motors. When you start noticing slow engine cranking, clicking noises, or dashboard dimming when turning the key, it is time to replace an aging power source before an unexpected breakdown occurs. Acting as the primary power source before the alternator takes over, these batteries deliver a strong initial charge to crank your motor and ensure dependable cold starts even during freezing winter mornings or severe summer heat. They are built to handle the demands of frequent short city trips and daily commuting, storing electrical energy to keep multiple cabin accessories and electronics running smoothly. By working alongside the alternator to maintain a stable electrical system, they stabilize voltage fluctuations to protect sensitive onboard computer modules. Designed and rigorously tested to meet strict performance standards, this replacement battery provides the reliable daily starting performance needed to give drivers lasting peace of mind. ACDelco Silver parts are a good choice for many vehicles on the road today.

Good Maintenance Practices:

  • Check the auto battery as part of regular vehicle maintenance.
  • Keep auto battery terminals clean and free of corrosion. To remove corrosion from terminals use a terminal brush.
  • Check the alternator and make sure that it is not charging too high or low - if the alternator is not charging properly it will cause the battery to not charge correctly and cause deterioration.

Signs that a battery may need to be replaced are:

  • Engine will not crank
  • Battery runs down easily
  • Battery will not recharge
  • Corroded terminals
  • Cracked/Broken cover or container
  • Frequent slow speed or short distance driving
  • Faulty battery connections
  • Low voltage/open circuit
  • Long-term vehicle storage
  • Frozen battery

Certain automotive parts can be recycled and remanufactured for future use. These parts have a "core charge" that is used as a deposit on the portion of the part that can be reused. The reason for this charge is to encourage the return of your old part. When the recyclable component from your old part is returned to us, the charge is refunded to you.

Frequently Asked Questions

The Cold Cranking Amps (CCA) test is the number of amps required to crank an engine for 30 seconds at 0 degrees Fahrenheit. Due to lower viscosity engine oils, gear reduction starters and smaller engines having the right amount of CCA is required but not too much. More CCA will not start your car faster. The Reserve Capacity test is the number of minutes that a battery will last with the headlights left on or at a 25 amp draw. Due to the increased electronics in a vehicle, having as much Reserve Capacity as possible is now more important than having the excessive CCA.

Most battery manufacturers put the 'CCA' rating right on the label of the battery. Be careful when shopping for batteries as some manufacturers put on the label a reference to 'CA'. This is a reference to 'Cranking Amps' this test is done at 32 degrees Fahrenheit and not at 0 degrees Fahrenheit like the Cold Cranking Amp (CCA) test.

This should be on the label right under the CCA rating of the battery.

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.

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.

Batteries that are Accessible Maintenance Free or Sealed Maintenance Free have a Calcium Additive to 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.

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.
