Motosport Maintenance-Free Battery with Acid

Pops right in, great inexpensive battery.

Ordered this battery, installed it and it had a hard time starting the bike. Put it on a charger and it read as fully charged after just a few minutes but would not start the bike, cranked way to slow. I called Rocky Mountain and they shipped me another one. I put that one on a charger first, read as fully charged immediately. Put it on the bike and cranked super slow. Load tested both batteries, one read as “bad” the other as “weak”. The first one had a date stamped on it that was a year and a half ago and the second one a date that was a year ago. Customer service at Rocky Mountain was excellent, battery not so much.

Did not last a year in my grandsons 90CC quad. Always stored on a battery tender.

Some how I got mixed up when I ordered the battery for my quad When it arrived i saw it was a Honda battery. ..The cost was way over priced for what I got. And only 6 month warranty .but what can i say . It fit great and i was ready to do the desert .I hope it stands up HONDA standards

Would definitely recommend this battery. Fits perfectly,works great! A good price, cheaper than I could buy locally.

needed a battery for the dirt bike, a 2014 KTM 350xcf-w six days basically i was a dee dee dee and didn't put it on a trickle charger when sitting and the battery died a horrible death. it was so dead it couldn't even let the bike run when you kick started it! so i ordered this one, and figured id put a charger pigtail on it so i could plug it in when it sits in the garage. So far so good. it had a full charge when it arrived, no acid bottles or anything! put it in, and after a few long cranks, it fired right up! i didn't review reliability because i haven had it that long, and performance for the same reason. will let you know how it works out.

The battery came ready to put in the bike. I didn't have to mess with any chemicals and it had a 80% charge on it when it arrived. I did charge it to 100% before I installed it but I think it would have been ok to instal it right out of the box

Battery was easy to fill with acid, and installation was a perfect fit. Whole installation took maybe five minutes.

Battery was missing on my ktm300 xcw with electric start. Added a dual sport kit and needed a battery to power the lights when the engines off. I don't use my electric start so it's purpose is only for powering the lights. It does that fine seems to hold a charge fairly well but it doesn't exactly have a hard life. I'd recommend it for a cheap replacement where you have a backup starting option such as a kickstarter.

I use this battery in my toys. I also work on atv's and its the battery I use for replacement. Never had a complaint. Easy install because its sealed and ready to go.

This was the mid priced battery. I haven't got to use it yet but it's correct and the service was efficient

low cost battery. perfect for trail riders where performance isn't a huge issue. had it about a year and it still starts my bike (which i store on a battery tender) but starts it slow, especially if it's cold outside. when doing dead engine start hare scrambles i really wish i had spent the money to get the lithium. starts faster easier and is a third of the weight. at the end of the day it always starts my bike and is fine for trail riders though.

Good battery, it fit just fine. It started my bike right up and has been holding charge.

Great battery for the price. Does everything it's suppose to.

i was in a bind, and needed a new battery quick. i called my local KTM dealer, and they wanted over $100 for this SAME battery. nuts right?
so, obviously i went on line and found it at Rocky Mountain atv for $37!
it showed up right in time for my race and fit perfectly. set it and forget it.
to be honest, i haven't even used the battery tender on it yet. maybe because i ride every week? not sure, but either way this is again an incredible value on a quality product.

Fully charged out of the box.

Bought this battery as replacement in 200xc-w. Liked the sealed feature in that no acid needed to be added and no chance of leakage in a fall.

-m-2013 KTM 200 XC-W--

I purchased this battery 6 months ago and its still going strong. No complaints at all and a good price

As good as any other $50 battery. If you have the money get the lithium ion battery.

I was worried about how this would ship and what it would look like when it arrived. no worries! gave it a little charge, popped it in and my daughter was off and riding shortly thereafter. Love Rocky Mountain ATV!! Best company around!!!

Bought this battery in January and it worked fine for the first two months, then I always had to hook it up to the battery tender to get to start up again. After about 8 months it started to leak acid all over the swing arm and now, obviously, it doesn't hold a charge at all. 6 month warranty, but after 8 months it is worthless.

The battery seems to be built well and was charged when received, hopefully it lasts. The price was pretty good too.

Worked great for about 2 years. Always on a trickle charger when parked so battery never went dead. Barely starts the bike now.

I needed a battery for a trip to Moab and another popular brand was on back order. I ordered the Motosport battery and I have been very impressed by it. Cranks the bike over quickly and holds a good charge!
