Yuasa Maintenance Free Battery YTX20L-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

This is my 3rd Yuasa battery

By Miguel A. on  Verified Purchaser

This is my 3rd Yuasa battery that I purchased, I don't ride as much as I used to I do used a tender and this battery last longer than other brands I own before.

Good deal


Killer battery

By Eddie on  Verified Purchaser

I was changing batteries in my Harley and V-MAX like every 18 months, tried a bunch of different makes of batteries. I finally asked a motorcycle dealer mechanic and he recommended YUASA, the first one lasted 5 years, all of them lasted 4yrs at least, the bike is 24yrs old. I use the 20L battery. Spins it over like the plugs are out of it.

Decent Battery/Decent Price

By Richard P. on  Verified Purchaser

Battery was as advertised. Fit perfect and works well. No complaints.


Great deal on great battery.

By Tom VV on  Verified Purchaser

This exact battery is still working fine after at least 9.5 years which is when Iacquired the bike. Could be a few years older than that. Only replacing it out of caution before a 7000 mile trip. Could not be more pleased.


Lasted more than 5 years.

By Len on  Verified Purchaser

These are fantastic, only battery I have ever used that lasted more than five years in my HD Softail.


Great Battery

By Brian on  Verified Purchaser

As described. Great packaging. Battery installation was straight forward, battery has the CA to start the bike very easily.


Great

By B. on 

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.


Worked

By Michael M. on  Verified Purchaser

Worked great. Nice job!


Yuasa battery

By Gary C. 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.

Good battery.


Satisfied

By Stephen L. on  Verified Purchaser

Exactly what I ordered. Couldn't me more satisfied. Will definitely use again, Thanks.


A superb battery that lasts a long time.

By Nathan 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.


Perfect

By David P. on  Verified Purchaser

Perfect fitment!


Battery

By Gregory H. on  Verified Purchaser

Great.


Best battery for my Harley

By Tom on  Verified Purchaser

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


Kuddos to Parts Giant

By Randall M. 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 Jeffery L. on  Verified Purchaser

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


Holding power so far

By Nazareno S. 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

By Bob F. on  Verified Purchaser

Battery was exact replacement of old battery and great price.


Quality

By Robert P. on  Verified Purchaser

Quality part and fair price!


Totally satisfied

By D.G. H. on  Verified Purchaser

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.

Awesome


Yuasa Maintenance Free Battery

By Arthur B. on  Verified Purchaser

I'm very pleased with the purchase of this battery. It was an easy install including adding the battery acid.


Yuasa Battery

By Rocky K. on  Verified Purchaser

Everything very good! Thank you.


As ordered and on time.

By erick n. on  Verified Purchaser

Received the correct part I had ordered. I would be willing to use again.


Off road

By Daniel B. 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.


Yuasa Battery

By Claude P. on  Verified Purchaser

Fit my 2007 KTM 250 XCFW perfectly!


Solid battery!

By Jeffrey A. on  Verified Purchaser

Charged fully w my trickle charger and she’s running like a charm.


I'm very happy with my order

By Marcos A. on  Verified Purchaser

Arrive in good condition I'm very happy with my order.


Great battery

By Donald M. on  Verified Purchaser

Had one in the motorcycle when I bought it. Took it out and someone marked 7-5-12. If it lasted almost 8 years. I said let’s try it again.


Battery

By Peter B. on  Verified Purchaser

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


Excellent Battery

By Earnest P. 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 Hrold on  Verified Purchaser

Excellent battery since once its received you add the acid.


Fit perfect

By Vick 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 kman4900 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 Olly 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 M.C. Loco 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?

By Anon.

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?

By Telmo S.

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 ?

By Ken G.

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.
