Product Description
Reliable Starting Power for Your Ride
Nothing ruins a planned ride faster than a clicking starter. When it is time to replace your old battery, the YTX9-BS AGM Maintenance Free Battery provides the dependable power you need to get back on the road or trail. This 12-volt battery is designed to fit a wide variety of motorcycles, ATVs, and scooters, offering a perfect balance of performance and value.
The "AGM" in this battery stands for Absorbed Glass Mat. For you, that means a much simpler experience than older style batteries. This unit arrives as a sealed, spill-proof system. You won't have to worry about messy acid leaks damaging your chrome or paint, and you will never need to check or add water. It is a "set it and forget it" solution that stands up to the vibrations of the open road.

Whether you are cruising on a Suzuki, tackling trails on a Honda, or navigating city streets on a Vespa, the YTX9-BS is engineered to meet or exceed original equipment standards.
Safety and longevity are at the core of this design. The leak-proof construction allows the battery to be installed at various angles without risk, and the lead-calcium alloy plates help the battery hold its charge longer during the off-season.

Frequently Asked Questions
Does this battery come pre-charged?
Most AGM batteries arrive charged, but we always recommend putting any new battery on a dedicated smart charger before the first use. This ensures the battery is at 100% capacity and helps maximize its overall lifespan.
Will this battery fit my specific vehicle?
The YTX9-BS is a very common size (6.00" x 3.44" x 4.19"). It replaces many popular part numbers, including the YTZ9-BS, CTX9-BS, ETX9-BS, and PTX9-BS. Please check the "Cross Reference" tab or compare your current battery's dimensions to ensure a perfect fit.
Do I need to add acid to this battery?
No. This is a maintenance-free AGM battery. It is factory-sealed or comes with a permanent sealing strip, meaning the acid is absorbed into glass mat separators. Once sealed, it stays sealed.
How do I maintain this battery during the winter?
Because it is a lead-calcium battery, it holds its charge well. However, if your vehicle will be sitting for more than a few weeks, we recommend using a battery maintainer or "tender" to keep the voltage at an optimal level and prevent sulfate buildup.

Customer Reviews
GREAT
The stock battery on my Royal Enfield Hunter 350 wouldn't be able to crank the motor at start up despite being fully charge. This battery was a perfect replacement and came almost fully charged. Zero issues so far.
Had to replace a 6 year old battery in my 2007 Suzuki DR650 as it would not hold a charge any longer.
Battery fits perfectly and the bike fires right up now.
We'll see if I can get another 6 years, but even just a couple is good for the price.
Easy to install. Perfect fit. Battery arrived in 2 days with free shipping. My factory Kawasaki battery lasted 5 years. I can't comment on how long this one will last. But so far, so good. The price was right, the 2 day delivery was fast, and the fit was perfect for my 2019 Z400.
Have purchased three products, at least half price of what O'Reilly asked
At roughly half the cost of other batteries, it seems like solid value since reviews seem to suggest that average battery life is 4 years. I bought it in Mar 2019 and it died in Dec 2023. I'm now back to buy another one.
Purchased to replace original BMW battery. Perfect fit for my 2019 G310R.
Arrived with 12.7 volts so I did the supplemental charge as recommended, with a Battery Tender Jr., for 3 hrs. Came up to 12.9 and I installed. It took longer to set the time and date than to install the battery. Fired right up, as expected.
Two day shipping included and no tax for Florida.
