Antigravity ATZ-10-HD 12V ATV Battery 525CA (w/ Re-Start)

Antigravity ATZ-10-HD 12V ATV Battery 525CA w/ Re-Start: 50% More Battery in the Sport Quad Case

The YTZ10 case family is the sport quad battery: Honda's TRX 400EX and 400X, Sportrax 250 and 300, Suzuki's QuadSport Z400, Z250 and LT-R450, Yamaha's Raptor 350, Polaris Predator 500 and Outlaw 525. New for 2025, the ATZ-10-HD RE-START puts a 9Ah lithium pack in that case, 50% more than the standard ATZ-10 and up to twice what other lithium brands fit in a 10 size, with 525 cranking amps at 3.15 lbs.

It is a RE-START, so the built-in jump start is there too: the BMS sleeps the battery before a month in the garage drains it flat and keeps a reserve. Press the button on top, hit the starter, ride.

Why the ATZ-10-HD in your sport quad

• 525 cranking amps for 250 to 525cc singles, hot or cold
• 18Ah lead-acid equivalent (9Ah lithium, 115Wh): the largest capacity in a YTZ10 case from any brand
• RE-START reserve and push-button jump start
• 3.15 lbs in the standard 5.9 x 3.46 x 3.62 inch YTZ10 case; sealed, shock and vibration resistant
• Replaces YTZ10S, YTZ12, YTZ14, YTX9, YTX7A-BS, YTX12A-BS and their BTZ / BTX equivalents (12 OEM sizes)
• 4-terminal design fits either terminal layout; full BMS with cell balancing
