Antigravity batteries use the latest in lightweight Lithium-Ion (LiFePO4) technology to pack huge power into the smallest possible size.
This 16-Cell "small case" 12 volt battery measures 4 5/8" L x 3 1/4" W x 5 1/4" H. It is smaller than most OEM batteries, but it offers a huge 480 cranking amps and weighs just 3.5 pounds. (We offer 2 lead-acid batteries that are close to this size, but they each deliver about 230 CA and weigh 11 pounds.) It has a similar cranking capacity to a 16Ah lead-acid battery* (our equivalent lead-acid batteries have 12Ah capacity and therefore can't crank as long).
This size is perfect for everyday use in large motorcycles (up to 1600cc modified and 96 CID V-Twins), or race use in motorcycles up to 2000cc. It can even power racecars as large as 3.5 liters (with alternators). It also makes an excellent and easy-to-carry jumper battery for cars without 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). 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.
