Best C7 Corvette Battery Replacement | Size & Reviews

2014 to 2019 C7 Corvette AGM Style Battery

The very Best C7 Corvette Battery Replacement fixes an issue for battery leakage problems.

The last thing you want is battery acid leaking onto your fiberglass car and destroying the structure!

Optima Yellow Top DH6 and other batteries of this type are built using AGM construction.  This type of battery  construction uses saturated (Absorbent Glass Mats) rather than gelled or liquid electrolyte. AGM batteries will not leak acid.  They are also less susceptible to vibration since the lead plates are not free to move in the electrolyte. 

In our quest to find the Best C7 Corvette Battery Replacement we compared an Optima battery against an OEM Delphi and Odyssey to see how well they match up.  At the end of the day any of these three batteries are a winner.  All 3 are AGM construction.  We will not recommend any other type of battery due to the lesser construction technology.  It's AGM or nothing!

What are the Best C7 Corvette Battery Replacement features and why these 3 battery brands are in our top 3 recommendations:

• AGM construction
• Durability
• Proven record of performance
• Leak proof
• Vibration resistant
• Modern looks
• 36 month warranty

What Batteries We Own

We've owned the Optima brand of batteries for over 15 years. We have found them to be very reliable, durable and constructed very well.  Early on we did accidentally discharge them too many times (because we did not own the charger) and they ultimately died early.  We relied on disconnecting the battery when the car sat, major pain in the but!  Since we starting use the battery tender all has been good!

We have the AC Delco still in service in our 2015 Corvette Z06 but suspect its on its last legs after 5 years and 33k miles.  If cost was a factor we would buy the upgraded AGM AC Delco instead. 

The Best Battery for C7 Corvette is?

Ultimately we will be changing to the Yellow Top DH6 when the Delphi finally quits.

Why Do C7 Corvette Batteries Go Dead?

Your Corvette most likely sits for more extended periods than other cars. Most of us Corvette owners are particular when we drive, so weeks can go by without starting or charging the battery by driving the vehicle.

The onboard computers draw energy from the battery 24/7.   This draw comes from chassis items such as running the door lock key FOB receiver waiting for a request to unlock.   

Every late model Corvette needs a battery charger.  The newer cars have so much parasitic draw from all of the computers a perfectly new battery can be dead in less than two weeks!  The Factory realized this and started providing this as an RPO option in late 2010 for Corvettes.  Get the same charger here!
