The Antigravity ATZ-7-RS is a premium, ultra-lightweight lithium-ion (LiFePO4) motorcycle battery engineered to directly replace the heavy lead-acid YTZ7S and YTZ5S batteries found in over 90% of modern enduro and off-road motorcycles. Weighing a mere 1.3 pounds, this battery sheds significant high-up weight from your motorcycle while delivering 150 cranking amps for faster, more reliable starts.
The defining feature of the ATZ-7-RS is Antigravity's proprietary RE-START Technology. The battery features a full internal Battery Management System (BMS) that actively monitors voltage. If you accidentally leave your ignition or an accessory on, the BMS will automatically put the battery into "sleep mode" just before it drains completely. This reserves just enough residual energy to start your motorcycle one last time. By simply pressing the RE-START button on top of the battery, it wakes up and provides the necessary power to fire the engine, entirely eliminating the need to carry a separate jump-pack or wait for a rescue on the trail.
RE-START Technology: Built-in jump-starting capability. The battery puts itself to sleep before draining completely, saving enough power to start your bike at the push of a button.
Ultra-Lightweight: Weighs only 1.3 lbs, offering up to a 70% weight reduction compared to an equivalent lead-acid OEM battery.
Full BMS Protection: Advanced internal circuitry prevents over-discharge, over-charge, and thermal damage while actively balancing the lithium cells for maximum lifespan.
High Cranking Power: Delivers 150 Cranking Amps (CA) to spin high-compression single-cylinder motors faster and easier than standard batteries.
4-Terminal Design: Features positive and negative terminals on both the left and right sides for universal fitment and easier accessory wiring.
Zero Maintenance: LiFePO4 chemistry holds a charge for up to a year without a trickle charger (provided there is no parasitic draw from the vehicle).

Direct OEM Replacement: This battery is the direct size replacement for these common lead-acid models: YTZ5S, YTZ7S, YTZ8V, YTX4L-BS, YTX5L-BS, and YTX7L-BS.
Common Applications: Widely used in the Gen 1 Yamaha Ténéré 700, Honda Africa Twin, KTM 690, 890, 1290... and many other makes and models.
Charging Requirements: Only charge with a lithium-specific smart charger like the Antigravity Super-Chargers. Never use a standard lead-acid trickle charger or a charger with a "desulfation" mode, as this will damage the internal lithium cells.
Cold Weather Wake-Up: Lithium batteries perform differently than lead-acid in near-freezing temperatures. If you go to start your bike on a cold morning and the starter feels sluggish, do not panic. Simply leave your headlight on or tap the starter button for 10-15 seconds. The internal current draw will physically warm up the lithium cells inside the battery. Once warmed up, the battery will deliver its full 150 cranking amps and start the bike normally.
