These are the First Motorsports Batteries with built-in RE-START technology & a Battery Management System (BMS) The New 4 Terminal Design means DUAL POLARITY!
The NEW Antigravity ATZ-7-RS battery is built with our groundbreaking RESTART Technology (built-in jump-starting) so you won’t ever get stranded with a dead battery again! This compact, lightweight Lithium-Ion battery directly replaces the OEM YTZ7S and YTZ5. 90% of off-road bikes use this size as well as some street bikes.
The new ATZ-7 Re-Start Battery is an extremely lightweight and high-power Lithium-Ion replacement for the heavy lead/acid battery found in many motorcycles including most every Enduro bike on the market. Additionally, the new ATZ-7 offers the first FULL Battery Management System (BMS) found on a Powersport Battery and includes low-voltage cut-off, over discharge, over-charge, and thermal protections with real time lithium-ion cell balancing.
(*Over-Charge protection will not protect from a faulty/old Voltage Regulator spiking Hi-Voltages to Battery. If you have a Pre-1990s Motorcycle replace your voltage regulator; it is over 25 years old and most likely broken by now.)
***USE A LITHIUM ION CHARGER TO AVOID DAMAGING THE BATTERY***
Please Note: For custom V-twin applications over 103 cubic inches or when a higher compression, modified motor is being used we do not recommend RE-START batteries due to the extremely high current draw of larger V-twin motors.

Please Note: if you own an older classic bike from mid 1980s and earlier you must update the charging system to a modern solid-state voltage regulator. Damaged or excessively old voltage regulators can over-charge and damage lithium batteries and cause smoking and melting of battery. This is NOT a fault of the battery!
