Cranking Amps: 480
Amp Hours: 16Ah (PbEq)
Weight: 2 Pounds 15.2 Ounces
The NEW Antigravity AT12-BS-HD-RS battery is built with our groundbreaking RE-START Technology (built-in jump-starting) so you won’t ever get stranded with a dead battery again! This is the HEAVY DUTY version of our standard duty AT12-BS-RS and offers more capacity/cranking power for those who need it.
The new AT12-BS-HD-RS is an extremely lightweight and high-power Lithium-Ion replacement battery for the heavy lead/acid YT12-BS battery found in many Motorcycles and Powersport Vehicles. The AT12-BS-RS 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. The new AT12BS-HD-RS also comes in a STANDARD DUTY VERSION (AT12BS-RS) if you don’t need the extra power and capacity.
(*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.

For replacement of all OEM Lead/Acid Batteries of same size.
Excellent for every day use in bikes up to 1500cc.
Excellent for Modified motors, Adventure Bikes and applications where extreme power and larger Amp Hour capacity are needed.
Great for use in Race Cars up to 600 Horsepower.
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!
Keep in mind that we have a Lithium Ion battery for just about ANY application!
