Yuasa Maintenance Free Battery YTX9-BS


Absorbed Glass Mat (AGM) Technology is an advanced battery design used in Yuasa's Maintenance Free Batteries that eliminates water loss. Once it's filled with acid the battery is permanently sealed - so you'll never need to fill it with water or check the acid level.

Long Life Because of its lead calcium design, the AGM battery will hold its specific gravity more than three times longer than conventional lead antimony types. This means much longer periods between charges when the battery is used in a standby mode, like winter storage.

And to remain factory-fresh the AGM battery is shipped dry along with its own pack of high-gravity acid that's added at the time of installation.

Sealed, Non-spillable Once filled with acid from its special packs, the AGM battery is virtually maintenance free. It's totally sealed and all of the acid is absorbed in the special plates and separators, so there is no need to worry about acid leaks on valuable vehicle parts and accessories.

  • Comes with pre-measured acid tubes that need to be added prior to installation
  • Includes a seal that is then placed across the top of the battery to create a sealed, spill-proof battery
  • Never needs refilling, but may need periodic charging
  • 1-year manufacturer's warranty

Prior to installation, it is advised that the user read and carefully follow the manufacturer instructions included with the battery. This battery ships with a container of battery acid that must be added to the battery prior to use. Battery acid is a highly corrosive strong mineral acid that reacts with metals, flesh and eyes that can lead to chemical burns and serious injury. When handling battery acid, it is advised that great care is taken when filling and maintaining your battery to avoid injury. If you are unfamiliar with the process of filling and or maintaining lead-acid batteries, it is recommended that you seek the assistance of an experienced professional.

The new Yuasa battery replaced a 9 year Yuasa battery that finally died. Easy setup along with the correct hardware, and it had the stated CA that made for easy starting.

Yuasa battery

By   on  Verified Purchaser

The battery that came put of my Honda Goldwing was a YAUSA, had a date on it of 5/14, and it died this spring. I figured if it last 10 years I'd go with the same brand. Was exactly what I needed.

A superb battery that lasts a long time.

By   on  Verified Purchaser

Wasted $200 buying a lithium battery only to have two of them fail spontaneous in 12 months. Had Yuasa in my bike as the OEM battery and they lasted at least 5 years. This is a quality product that is built extremely well, lasts a long time and costs half what the worthless lithium batteries cost. And frankly its a safer product since you never have to worry about it overheating and burning, or not working in extreme temps. Should have just got this from the start as I could have saved $100.

Best battery for my Harley

Excellent products competitively priced. Great battery for my Harley. Lots of power to start my bike.


Kuddos to Parts Giant

By   on  Verified Purchaser

I've only had the battery for a short period of time, and it works, so, it's too early to give it an honest rating, because I would expect any battery to last at least that long, and so, my rating is paper, not gold. I was impressed with the packaging that my battery arrive in! Best I've ever seen! Thank you for the extra care you took to protect my merchandise!


Very good quality!

By   on  Verified Purchaser

Always had great results using Yuasa batteries! This was the original equipment battery on my bike.


Holding power so far

By   on  Verified Purchaser

This is holding power so far, but not cold enough yet to check how the CCA holds and did not go for a long ride, battery is installed to a 2004 motorcycle that has more than 270k miles.


Great price

Battery was exact replacement of old battery and great price.

Totally satisfied

The battery fit my bike and connectors were same as original so no problem installing. I charged the battery for a short time to reach full charge and it starts the engine much faster than the previous battery did. I am totally satisfied.

Off road

By   on  Verified Purchaser

A great battery, have been using them for years. Tried others but none matched up. I used to add fresh acid to them when I was a kid and could even get an extra year out of them. That’s when they had the yellow caps.

Standard battery. Easy setup and charge. Hope it lasts a long time.


Excellent Battery

By   on  Verified Purchaser

I’m glad I bought this battery. I was really surprised how much cranking power it has. This battery is better than the ones I’ve been buying.


Yuasa battery at Parts Giant

By   on  Verified Purchaser

Excellent battery since once its received you add the acid.


Fit perfect

By   on 

The battery is delivered dry with the acid in a plastic container. Adding the acid was simple and fool-proof. Simple to install. Fit for my bike was spot on.


Easy Fill

By   on 

The batteries that are out there that are suppose to do things better and easier etc do not support their claims some times. Adding the battery acid into the battery before use is a smart thing to do as that battery starts its life as soon as air and acid hit the plates. A battery that has been sitting on a shelf already filled has lost a year of its life.


The best all around battery

By   on 

Excellent products as always. This battery was a perfect fit for my bike. After trying numerous batteries, I decided on this tried and true legend.


As good as it gets.

By   on 

My '05 Triumph Bonneville came equipped with one of these batteries. It finally died last week but only after I left the ignition on overnight. It didn't die itself, I killed it.

Questions & Answers


I have a EU 3000 IS Honda Generator, it came with a Yuasa YTX9-BS battery. I'm worried about the size. is all the YTX9-bs the same dimensions?

Yes, a YTX9-BS will be the same no matter where/when it is purchased from. Yuasa doesn't change the size of their batteries.

By Andy

Does the acid comes with the battery or do i have to buy it separated?

All of Yuasa's Maintenance Free Batteries ship with a pre-measured acid pack in the box. There's no need to buy any battery acid in order to charge and use the battery. Best of all, because the acid pack is pre-measured, there's nothing left over to dispose of and you don't need to bother measuring fluid level. Just add the acid, put the permanent acid port cove on, charge as directed and you're good to go!

By Staff

Is this a brand NEW, not reconditioned battery ? How about the warranty ?

All Yuasa batteries we sell, and everything else that's available in our store, is brand new. We don't sell reconditioned batteries or any other parts. Ass Yuasa batteries are covered by a one year manufacturer's warranty. If, at any time during that period you have a problem, just let us know and we'll be happy to get you sorted out.
