YT4L-BS 12 volt high performance battery by Scorpion. These are no ordinary replacement batteries, but a true high performance AGM battery that is designed to meet and even surpass the standards set by your vehicle’s OEM manufacturer.

Scorpion is dedicated to manufacturing only the best replacement batteries, to uncompromising standards. Manufactured specifically for BatteryStuff by one the largest makers of ATV and Honda motorcycle batteries in the world. While these batteries are ‘new’ to the US market, they have become one of the largest powersports battery manufacturers in the rest of the world simply because they build only quality products.

By continually updating and modernizing their manufacturing process, the makers of Scorpion batteries have achieved a position in the Powersports industry that is unrivaled around the world. Scorpion is the ONLY battery in the U.S. to currently offer a real MANUFACTURER backed warranty on their products. What does this mean to you? This means that Scorpion is confident enough in the quality of their batteries that they are not afraid to stand behind them. The rest simply ask their distributors to ‘ante up’ and cover the failure. This confidence alone is why BatteryStuff is excited to offer this new battery.

Be assured that with the YT4L-BS High performance battery you are buying quality, at an affordable price.

Excellent product so far
Needed this battery for an Eton 90 Thunder quad. Battery packaged well for shipping. Installed upon arrival and battery was a perfect fit. Battery has been operating well.

Excellent value says repeat customer
Being AGM means NO vent hose so no corrosion! AGM or LiFePO4 are the only way to go these days. AGM for a super value or LiFePO4 if you need more cranking amps and/or light weight. Fast shipping and top quality for you smaller battery needs. My second Scorpion battery from BatteryStuff. A++

Replacement for OEM Z125 Battery
I've been using Scorpion replacement batteries for quite a few years now in various machines. Top quality and very reasonable prices. I recommend them to all my riding friends.

Product tested at 0 volts when received. After a couple hours on a trickle charger, volts rose to 12.87. Voltage has been good since the original customer re-charge.
Product has performed as anticipated.
