Antigravity's RE-START line changed what a car battery can do: if the H5/Group-47 is ever discharged, you press the button on the included wireless keyfob, start the car and drive away. No jump pack, no roadside assistance, and no need to open the hood.
The onboard Battery Management System is what makes that possible. It monitors the pack continuously, and if it senses over-discharge it puts itself to sleep while reserving just enough energy to crank the engine. The same BMS handles over-charge, short-circuit and thermal protection plus cell balancing, which is why Antigravity expects 7-9 years of service depending on use and climate.
This is an exact OEM drop-in for the H5/Group 47 case size, so no tray or modification is needed. At 14.25 lbs it is roughly 70% lighter than the lead-acid battery it replaces, and it still cranks harder: 1500 cranking amps, with starting performance better than a 90Ah lead battery.
