Yuasa YUAM327BS YTX7L-BS Maintenance Free AGM Battery with Acid pack

This is a Genuine Yuasa battery which is the only way to go if you truly need reliability as it is the OEM choice for many motorcycle and power sports manufacturers. That being said these battery’s rarely have any issues with my past experience of the Yuasa brand but the battery I ordered had an issue that caused the acid to all boil out during initial filling of the battery. I reached out to the seller and they promptly sent me a replacement. Can’t go wrong with great customer service and good product. Don’t be fooled by cheaper brands. Trust Yuasa

Perfect fit for 2014 Honda CRF250L. Thought I had an electrical problem because my float chager said my old battery was charged to 100% but it would not start the bike. Just made a noise like a quickly repeated clicking sound. Wouldn’t turn motor over (even while hooked up to the float charger and battery showing 100% charge). Assumed I had a bad electrical connection somewhere. Eventually I put a big charger on the bike and set it at just 2 amp (trickle charge, but more than float charge of 1 amp). Bike started right up. At that point I figured it’s the battery. Had my battery 3 days later. Added the acid (very easy, just be careful, read, and use common sense). Charged for 3 hours then put it on the float charger to top it off. Bike started right up. I’ve bought 4 or 5 of this brand of battery now. They are good quality batteries.

This is the same brand and battery than was original equipment on my Suzuki when it was new and the battery lasted 8 years, so why not go with a proven and reliable product? Note. It seems obvious once its done, but the cap that is over the battery acid container is also the cap used to cover the battery, once the acid is dispensed. Also, the foil on the acid container remains in place and is pierced when placed over the empty battery, filling the cells.

The Yuasa YTX7L-BS battery is the OEM battery for a 2010 Honda Elite NHX110. You will have to add the electrolyte packet to the battery, but it is very easy and quick to do. The battery did not come with any hardware to attach it to my scooter's wiring, so I had to purchase the hardware separately. You will need short M5 bolts and rectangular terminal nuts. Being a Yuasa, I expect the battery to last several years (with proper maintenance of course).

Bought for my Honda CBR250R. It previously had a different brand battery which was too small and had a cell fail after 6 months. A friend recommended this brand. I was torn between this battery and a lithium battery, but this was cheaper (1/4 the cost of a lithium battery) and would serve just as well for my riding conditions. Fits perfectly. Adding the acid was easy, just be careful not to spill it. I let it charge on my battery tender overnight before installing it. It's been totally fine for the past month with no issues whatsoever. Time will tell.

It's hard to write a decent, honest review, since this is a long term item, and I just got this one a few weeks ago. I'll do my best based on installation and initial operation, and unless you read otherwise here, feel free to comment to me in 5-7 years or so and I'll try to update my review. My last one, same brand, was reliable for a VERY long time, and that kept me from rating a lower 3 star. The problem I had won't ever get me to rate it a 5-star though, just skip to the end for that. Overall, happy with it so far, with a small difficulty that got my dander up at the end of this review. It's the first time I've ever gotten this kind of battery, where the electrolyte (sulfuric acid) isn't already in the battery, but in a heavy-duty plactic container, almost a type of magazine (like the kind you put bullets in, not the kind you read! You're a very silly person, aren't you?) which they need to do for safety in shipping. I was pretty nervous about it, but I had no reason to be. I had gloves, water, glasses on, etc., which I still recommend having available, as well as someone within hollering-at distance, but I feel really like a dork for freaking out about it, now. It's simple and easy. Just follow the instructions. Look at a video online, too, it'll increase your confidence %100. Don't worry about it to much, it's really hard to mess up. Use a stable surface, sheltered from the weather, well-ventilated and away from people. Your kitchen, bathroom, and bedroom are all bad ideas, in other words. Think garage or shed. Away from kids, or neighbors who may prod at it). Pop off the bits you need to, flip the electrolyte magazine over (it's still sealed like wax bottle candies for now) and pop it on top (each chamber gets punctured by a straw about as thick as a pencil that just barely sticks out of the corresponding cell. It's kind of like punching a bunch of juice boxes at once, only upside down. And with sulfuric acid). Air will start bubbling in to the different acid chambers. If you see one or more not bubbling, gently tap it until they do. Leave it alone, now, until the chambers are all empty. Should take 15-45 minutes. If not, make sure there are bubbles, you may need to tap it again until there are and come back later. Carefully take the empty magazine off (the only drop of acid I spilled, a tiny one, right onto my glove) and dispose of it properly per your local etc. As an example, for my "local etc.," for sulfuric acid that mild, was "rinse carefully with lots of water and recycle empty container." Seriously, acid like that may be nothing to play around with, but it's also nothing to freak yourself out about too badly. Kind of like chlorine for a pool (only, an acid, not a base): respect it but don't worry all that much. Let the battery sit. It's usable almost right away (30 min) if it's an emergency, but give it from a few hours to just overnight. Install it. Which comes to the only problem I had with this. There is nothing, no hardware at all, that comes with it. With small batteries like these, you are expected to tighten tiny bolts in order to hold the leads against the battery's contacts. These contacts are a bit like hollow cubes that have a hole for the bolt, but aren't threaded to accept a bolt. There is supposed to be small, square, nuts inside the contacts that are big enough for the bolts to bite into, but too big to rotate within the contact, ensuring you can get a firm electrical connection without fiddling about too much with tiny tools in cramped spaces. My old bolts and nuts got unintentionally recycled with the battery. THE BATTERY DOES NOT COME WITH THESE 4 TINY BUT ESSENTIAL PIECES OF HARDWARE. This battery is the only thing that can make my vehicle work, understand this. I have no independence without it, it's way too many miles in the Florida sun to anything close by, heat stroke and hospitalization would cost way more than a battery. Which is why I needed to get it through Amazon, it needed to be delivered. But in the end, I had to cajole and bother friends and family until I could get a ride to a hardware store, to get $1 worth of tiny pieces of metal, that still didn't fit until we ground the sides of the nuts down. They should have been included with the battery, it would have been easy and cheap to do, and seeing that those tiny bits are the *only* things that *don't normally come with what you're using the battery for,* not to mention a little hard-to-find if you need to walk everywhere or don't want to wait yet another week for it to come in the mail (shipping probably costing more than the nuts and bolts, which may not fit because the instructions don't tell you what size you'd need). Sorry for the negative rant, didn't mean to write a novel. I had my last Yuasa battery for six years and it worked great until it died, which is impressive enough for me to not rate this three stars. There isn't much they can do to get me to rate it 5, though. EDIT Oct 2017: Has been idle for over a month while I recover from a badly broken ankle. Still working fine, started up at once.

Good battery, a bit expensive, but I got it after I was left stranded by a cheap gel battery that failed after only 3 months and 300 miles. You do have to mix the acid and add it to the battery yourself, but to me it is well worth the hassle to know for sure that your battery chemicals are brand new. UPDATE 13 November 2023 - this battery died after about 5 years. I did not maintain it very well. It was installed in my old motorcycle that only gets ridden a couple of times a year. Many times, I let the battery go several months without being charged. So it lasted for 5 years with poor maintenance. I am pleased with it, and I will buy another one.

I bought this battery July 2019. Today’s date is 6 Jan 2025. Battery still works but has a steady state of charge of 12.2 volts. It is starting to go. So Yuasa still makes great battery’s as of 5 years ago. Hope this info helps.

Good quality and half price of in town.

buen producto de buena calidad

I've never had to put the liquid into the battery before it was interesting but what a great deal for very little work.

Fresh charged very fast at 2A. Rewired signals for over a couple hours playing with the power off and on, not running. Battery held almost full charge. And fires in the first 2 turnovers everytime since. Great quality, fast shipping and great brand. Strongly recommended!

Showed up 2 days after I ordered it, when I selected standard shipping, it was a little sketchy putting the acid in myself (make sure you wear gloves) however I appreciate that I didn't get a box full of leaky battery. Put it in my bike and it worked as expected.
