Long lasting performance and good price Yuasa is the first name in power sports batteries for a reason, they perform well and last long so why buy anything other that Yuasa for your atv, sled or dirt bike? May 19, 2014
Good battery Hey for the money you definitely can't get a better battery I have a Scorpion, Battery Tender, Garmin GPS, and a PCv so I had to go to the hardware store because the stock bolts were not long enough to reach the blocks at the bottom of the +/- terminals. A little annoying it wasn't a problem with my last battery but an easy fix. The top seals very tightly. Best parts are that it doesn't get any fresher than make at home, and it's made in the USA that makes a difference to me and US & German batteries seem to be the best. Watch the video on YouTube gives information on immediate usage etc. June 9, 2014
Complete garbage and a waste of my money Fresh out of the package the battery was dirty and looked used or damaged, even though everything was still sealed. The instructions are as simple as it could be. Take off the tab, open the electrolytes, gently but firmly push them down until the seal puncture. Wait 20 minutes. There is literally no way of messing up, short of dumping acid on yourself. The problem is, after puncturing the seal, the electrolytes WILL NOT come out. After waiting 15 minutes nothing happened. So i sat there and gently tapped the top for about 20 more minutes, 3 tubes on one side drained slightly, the other 3, not at all. Even though I'm outside, there's a horribly strong gas smell that makes me want to vomit. After leaving it alone for another 30 minutes to see if it will drain (now that it's started) it has literally done nothing. Even if it finishes draining (it still hasn't moved after another 10 minutes) I'll be too afraid to use it. At this rate it's probably going to fail or blow up on me, no thanks. 0/10 absolute garbage. Have never be so disappointed in an item before. June 4, 2014
Hey! It's Yuasa! Revzilla service was typically quick and accurate. I ordered the battery on Monday and it arrived less than 48-hours later Wednesday. Unlike my battery purchase last year from another seller, this one arrived on time and in brand new, unopened condition. The battery fit exactly like it's supposed to, and it produced a nearly full charge after I activated it; the Battery Tender showed "green" within 15 minutes of connection. Typically solid Yuasa performance and typically solid Revzilla service. May 19, 2014
Great quality battery Got this battery as a replacement for my sv650, always good to go with a well known brand with a good warranty. they always put out a good product as long as you take the proper steps to prepare the battery it will last a long time and never leave you stranded. May 8, 2014
cant go wrong with oem eqp. my battery was giving me a low charge reading so i bought a new one. i was looking at the cheaper ones but after reviews saying there cheaper ones lasted 2 years i decided to go big and not go home. lol. it keeps a full charge at 12.8 volts. easy to install the acid and charge. yes you have to charge. if you dont have a charger just fill the acid and take it to autozone. they will charge it. but this style is better than sealed battery that comes charged from factory. they sit on the shelf and lose the charge life. this battery life does not start till you put the acid in. so you get a NEW battery. also once the acid is in you put a seal over it and never need to fill again. overall i am glad i went with a real battery not cheap. everytime i go cheap i end up having to buy the cheap one than the better one because the cheap one breaks out fast. get your money worth and invest over buying. hope this helps someone..

Brian M: Yuasa is the best, that's it, hands down. Apr 28, 2014
john e: I chose this battery beause it is the original model from my 2011 KTM 300 XC. I noticed that your list of models that fit this battery did not include mine. After measuring my old battery it would appear that they are identical. This may cause confusion to anyone that can't read a tape measure. Apr 15, 2014
