Antigravity H8/Group-49 Car Battery

Awesome weight savings and retailer

Have always wanted to try the AG and shave 40 lbs off the F Type like reviewer George H. As my MB's battery no longer held charge and luckily I could simply repurpose the Jag's still-good OEM battery to it, combined with the terrific price WDL had during Black Friday (lowest anywhere by a long shot), I pulled the trigger. The AG is well made, direct drop in (H8/Group49) and so light at 19 lbs it's carried with 2 fingers! It started the supercharged V8 right up and the engine auto start/stop worked again to boot. Even in my car pushing 640HP, acceleration is more brisk, particularly evident going low city speeds in higher gears. Looking forward to see its long-term reliability and its startup performance during the East Coast winter. Purchasing from WDL was GREAT. They responded quickly to my questions and the battery arrived direct from AG within 8 days of ordering. Other retailers I checked were also out of stock but either had no ETA or said several weeks.

Super Battery

Battery was purchased primarily for weight savings which for me meant 42 less pounds and the added plus of a stronger battery. WDL was just great in providing me with advice and they followed through with excellent communications and super fast delivery. I would like to especially thank Mel for her help and assistance in this purchase. An absolutely excellent company to do business with!

Worth the upgrade

Arrived very quick, double boxed and ready to install. Last 8-10 years (3 times longer than a standard AGM), 1/3 the weight (losing 40 lbs is a lot), and more useable power…. It’s well worth the price. Add in the “restart”, jumpstart capability and it’s a huge convenience when you need it.
