Antigravity ATX20 12V Jet Ski Battery 680CA (w/ Re-Start)

Antigravity ATX20 12V Jet Ski Battery 680CA w/ Re-Start: The Battery Under Nearly Every Sea-Doo and WaveRunner Seat, With a Jump Start Built In

Almost every personal watercraft on the water starts on a YTX20L: Sea-Doo's GTI, GTX, RXP, RXT, Fish Pro and Spark, Yamaha's WaveRunner FX, VX, GP and EX, Kawasaki's Ultra and STX. The ATX20 RE-START drops into that tray at 3.8 lbs with 680 cranking amps, then adds the thing lead acid never could: a jump start built into the battery.

A ski sits on the lift for a month, then has to start on the water with nobody around to give it a jump. The RE-START BMS sleeps the battery before it goes flat and keeps a reserve. Press the button on top, hit the starter, ride. No cables, no tow back to the ramp.

Why the ATX20 in your ski

• 680 cranking amps spins a 1000 to 1600cc triple or four hard, hot or cold
• RE-START reserve with a push-button jump start: never stranded on the water by a drained battery
• 3.8 lbs replaces a lead-acid brick that weighs close to 14; sealed, vibration resistant, no acid to spill in a hull
• Replaces YTX20, YTX20L-BS, YTX20H-BS, YTX20HL-BS, YTX15L-BS, YIX20HL and the GYZ20 family (15 OEM sizes)
• 4-terminal design fits left- or right-hand positive trays; mount in any orientation
• Full BMS: over-charge, over-discharge, thermal protection, cell balancing
