The best battery for C5 Corvettes fixes an issue for battery leakage problems.

When this battery leaks, it  leaks onto the:

  • computer
  • wiring harness
  • frame
  • vacuum hoses for the A/C controls. 

Yikes! When the traditional lead acid battery fails and leaks, the battery tray directs the acid straight onto your powertrain computer! 

Optima Redtop Part # 8004-003 34/78  (fits 97-00) 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 Battery for C5 Corvettes, we compared two different Optima batteries, one OEM brand and one of the leading competitors to see how they match up.  At the end of the day, any of these batteries are winners. 

All batteries are AGM construction.  We will not recommend any other type of battery due to the lesser construction technology.  It's AGM or nothing!

Key features of why these 3 battery brands make our top 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 accidentally discharged them too many times (because we did not own the recommended Corvette battery tender) and they ultimately died early.  We relied on disconnecting the battery when the car sat, major pain in the butt! 

Anyways lesson learned! Since we starting use the safest battery tender we could find all has been good!

Why Do C5 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 that 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!  

There is great info on Lead Acid Batteries at Battery University if you want to learn more about battery technology!
