Antigravity batteries combine the latest in lightweight Lithium-Ion (LiFePO4) technology with an "OEM size" case for easy weight loss!
This 24-Cell 12 volt battery is the same size as the popular YTX-12 motorcycle battery (6" L x 3 7/16" W x 5 1/8" H), but it offers an incredible 720 cranking amps and weighs just 3.25 pounds. (We offer a high-quality lead-acid YTX-12 battery which delivers about 220 CA and weighs 11 pounds.) It has a similar cranking capacity to a 22Ah lead-acid battery* (our lead-acid YTX-12 has a 12Ah capacity and therefore can't crank as long).
This size is perfect for everyday use in very large motorcycles (up to 2500cc or modified V-Twins up to 96 CID), or race use in cars as large as 5.8L V8s (with alternators). Female M6 terminals offer excellent durability. For direct bolt-in automotive applications, we offer an M6 Female to Brass Post Battery Terminal Adapter Kit (Part No. 4156-102, sold separately). The positive terminal is located on the right side. Made in the USA.
* Pb-Ah Equivalent. This is not to be confused with Amp-hour capacity. Lead-acid batteries deliver a low-amperage current over a long period of time (for example, a 12Ah lead-acid battery can theoretically deliver 12 Amps for an hour). LiFePO4 batteries deliver a brief high-amperage current and then recover quickly (as in starting an engine). This battery is not designed to deliver a sustained current, and it should never be used in a total-loss electrical system. Never use a trickle charger or standard lead-acid battery charger on a LiFePO4 battery.
Note: DOT regulations will only allow us to ship Antigravity batteries via UPS Ground service. UN regulations will NOT allow us to ship Antigravity outside of the 48 contiguous states. USPS will not accept lithium batteries for transport by mail.
