(LI) Antigravity Q85/Group 35 Lithium Car Battery 40Ah, RS

Brand: Antigravity Batteries

Antigravity batteries combine the latest in lightweight Lithium-Iron (LiFePO4) technology with an "OEM size" case for easy weight loss!

This 12 volt battery is the same size as a standard Q85 or Group 35 car battery (9" L x 6.85" W x 8.6" H), but it offers an incredible 1500 cranking amps and weighs just 16.5 pounds. It has a similar cranking capacity to a 40Ah 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!

The Q85/Group 35 size fits many Japanese performance cars, including Acura, Mitsubishi, and Subaru.

* 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.
