2016 Corvette Battery Size

The 2016 Corvette takes an H6 (Group 48) battery, like the OPTIMA H6 YELLOWTOP, which is a direct-fit upgrade for the OE battery. However, Corvette owners may notice the H6 YELLOWTOP is one of the heaviest batteries around at 54 pounds. So why would GM choose a battery that weighs so much in a sports car that might seem to benefit from lightweight components? Because Corvettes use A LOT of electricity, even when the engine is off.

As newer vehicles come with increasingly advanced features, the electrical demand has increase significantly. A 1976 Corvette could use a Group 75/25 REDTOP that only weighs about 33 pounds, but those cars are far more simple from an electrical perspective- no OnStar, no anti-theft systems, no key fobs that activate the onboard computer systems when they get close to the vehicle, etc... GM may also realize many Corvettes don't see regular use and may only get driven a few times per month.

That combination of high electrical demand and infrequent use can quickly discharge any battery. If the battery is physically larger (and heavier), it will take longer to discharge than a smaller (lighter) battery. Perhaps they figured out that extra 20 pounds worth of lead and acid is able to hold enough energy to handle the driving habits of a modern Corvette owner? Either way, if you own any Corvette or any other car that doesn't see regular use, your battery will work better and last longer if you keep it topped off with a quality battery charger, like the OPTIMA Digital 1200 Charger & Maintainer. We're so confident the OPTIMA Digital 1200 will extend the life of your battery, that we'll add an additional year of warranty coverage to your OPTIMA battery, if you buy your OPTIMA battery and a Digital 1200 from us at the same time.
