Key Features – RESTART Lithium Motorcycle Battery

• Most Advanced Lithium Battery on the market.
• World’s First Battery with Built-in Jump Starting, using our RE-START Technology.
• World’s First Powersport Battery with a FULL Battery Management System (BMS) including Over-Discharge, Over-Charge*, Thermal Protections and Cell Balancing.
• RE-START TECHNOLOGY: The RE-START Battery intelligently monitor its status; if it senses over-discharge it will put itself into a sleep mode, yet saves enough energy to allow you to RE-START your vehicle. Simply press the RE-START button on the battery.
• LONGER LIFE: Up to twice the lifecycle of lead/acid, and other Lithium batteries due to a full Battery Management system.
• HI-POWER: Up to 2 Times the Cranking Amps of similar sized lead/acid batteries. Better Starting and higher voltage at start-up.
• ULTRA LIGHTWEIGHT: Up to 70% lighter than equivalent lead/acid battery. Up to 15 lbs in bikes or 40 pounds in some Race Cars. Carbon Fiber costs thousands to lose a pound of weight; with our LiFePO4 battery, a few hundred dollars will lose roughly 8-15 pounds and offers better starting and handling!
• NEW 4 Terminal Design: allows easy installation in any vehicle. Fits right or left hand Negative or Positive connections. No more looking for the correct Terminal locations in certain bikes.
• LOW SELF-DISCHARGE: The RE-START Batteries do not self-discharge like Lead/Acid Batteries. They can hold a charge up to a year provided there are no Parasitic Drains (accessories that draw power when the bike is off, i.e. alarms, ECUs, GPS, heated grips, and other accessories the vehicle might have).
• DURABILITY: Our lithium batteries are shock and vibration resistant making them perfect for Racing, and other applications requiring a durable battery.
• MOUNTING: You can mount our battery in any orientation, there are no liquids to spill or drain out.
• ENVIRONMENTALLY SAFER BATTERY: No Acid or Heavy Metals such as Lead, Cadmium, or Mercury.

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.

NOCO 12v & 6v Lithium Motorcycle Battery Chargers:

One of the most critical components to get right when you purchase a Lithium Motorcycle battery for the first time is the charger. As lithium batteries need to be charged in a specific way you can not use your standard battery charger. A must is to pick up one of our most powerful, highest-performing, energy-efficient, and compact chargers yet. The NOCO GENIUS range is a 6-volt and 12-volt battery charger and battery maintainer for Motorcycle, automotive, marine, and deep-cycle batteries, including Lithium-ion, flooded, gel, AGM, and maintenance-free batteries.

BEST USES FOR LITHIUM BATTERY

• For replacement of all OEM Lead/Acid Batteries of the same size.
• Excellent for everyday use in bikes up to 1000cc.
• Excellent for Race Motorcycles up to 1400cc.
• Replace YTZ & YTX Models
