Antigravity batteries combine the latest in lightweight Lithium-Iron (LiFePO4) technology with an "OEM size" case for easy weight loss!
This 20-Cell 12 volt battery is the same size as the popular YTX-20 motorcycle battery (6 7/8" L x 3 7/16" W x 6 1/8" H), but it offers a whopping 680 cranking amps and weighs just 3.8 pounds. It has a similar cranking capacity to a 20Ah lead-acid battery*. Re-Start technology automatically shuts down the battery in the event of a parasitic drain. Simply press the restart button on the top of the battery to start your vehicle!
This size is perfect for everyday use in very large motorcycles (up to 2200cc or modified V-Twins up to 96 CID), or race use in cars as large as 5.0L V8s (with alternators). Two sets of terminals put a positive terminal on both the left side and 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.
Note 1: This battery should NEVER be used in a total-loss electrical system. This battery will not deliver a sustained current.
Note 2: This battery will not work on a modern vehicle with a stop-start system or a "smart" charging system. These systems are specifically set up to drain the battery down below the 12.4V shut-off point, which will trigger the Re-Start system to turn the battery off.
Note 3: Never use a trickle charger or standard lead-acid battery charger on a LiFePO4 battery.
Note 4: 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.
