YUASA Standard Battery with Acid

Put acid in, charged battery and it works well.

The Yuasa battery was a good replacement for the original one that came with the Yamaha when I bought it used. It was the right size which is important because you have to take off the seat to change the battery. The battery arrived when Rocky Mtn. said it would, so I didn't wait long.

I looked for the best battery I could find. I had a Yuasa in my 1986 Honda Fourtrax that I replaced after 5 years because I thought these small batteries didn't last long. I was wrong. I put the 5 year old battery in my lawn mower and it was good for a total of 11 years. The average lawn mower battery only lasts 2-3 years, so I felt that this brand is the best.

I am a loyal customer of Rocky Mountain and as always, received my order in less than a week. The battery was installed in my atv and I was riding it same day. Excellent quality and very affordable

I have had my Cat for 17 years and I have to say the YUASA fired it right up and it's running fine. Highly recommend this battery.

Good so far but not long unuf to review. Has more starting power than the tusk ever did. I dunno. Have to see thru winter.

Good battery, these will last a couple of years with no problems. I just picked up a lithium battery and may never go back to the acid ones.

I really like this battery, this purchase was actually my 2nd. However, I was quickly reminded of the two things I really don't like about it:
1. The "fill line" is very difficult to see properly. Which on most batteries isn't a problem because the acid will settle before you charge. However, with these it doesn't very much. Which causes "bubble over" when charging for the first time. And in my case, that meant a ruined kitchen counter thanks to the acid splatter. Not a problem if you can see through it, just make sure you take your time!
2. I really don't like the terminal screws compared to other batteries. On my Polaris 570, it's hard enough to get under to connect it - let alone trying to hold those bottom nuts in place while inserting the post screws. Having a permanent thread on that post (or a square nut that held in place) would be a vast improvement.
Other than those things - the battery is the best I've used over the years in all my machines. Starts fast for years.

Pretty decent battery. Added the provided acid, charged for the recommended time on a trickle charge. Installed in my 1998 Yamaha Big Bear 350 4x4, it cranked up, worked well on my wife and I's 40 mile ride.

You can't beat a Yuasa battery. I have used others but none last nearly as long. Most will last 8 years if used regularly. Spend the few extra bucks.

Great deal for a good battery.

One of the best acid type batteries out there.

Just follow the instructions that come with the battery and you won't have any problems. I had to detour from them a bit because I only have a 2amp trickle charger and it call's for a 1 or 1.5, but it should work just fine. With my battery on a 1 amp charge it is supposed to take 15 hours after filling it with acid.

Good battery for the price

I bought this battery because it beat all local shops in price. Can't say enough about RMA; have used them for years, always great service and delivery!

Once I received the battery, I was unaware that it was not a sealed battery. Battery comes with acid, but not a tube to fill the battery. This battery is a maintenance battery which requires water every few months, assembly, and charging. I took this to a local shop for which they did for $8. For ATVs where the battery is not easily accessible; or you tend to roll your bike a lot, look at a sealed battery.

Overall, the fit and strength of the battery can't be beat for the price!

This was the stock oem battery. Fit perfectly at a great price.
