Dirt Bike Battery

When you’re ready to ride at the motocross track or on a scenic trail, nothing beats the convenience of a good battery that is ready to go. So if your battery is on the decline, make life easy again with a new dirt bike battery from Rocky Mountain ATV/MC. We carry a variety of dirt bike batteries to suit every style and budget.

We have traditional lead-acid batteries, lithium ion batteries and gel cell batteries. We carry leading brands like YUASA, Ballistic, Shorai, Antigravity, Bike Master and more. All you need to do is enter your bike’s make, model and year, and we’ll show you exactly which batteries will fit your motorcycle. (If you prefer to stick with the OEM battery, just click the OEM button at the top of the page.)

Even if your existing battery is still going strong, there are plenty of reasons to replace it with a better aftermarket one. For example, a maintenance-free battery can remove the headache (and risk) of continually checking and adjusting acid levels. And if you’re looking for a lightweight motocross battery, there’s nothing better than lithium ion! It’s one of the fastest (and cheapest) ways to shave a pound or two off of your motorcycle’s weight.

    Awesome Battery

    Have had this battery for a few years now and have not once charged it. It fires up every time, even after a long winters nap in the garage. Have this battery for both quads and the dirt bike.

  • YUASA No Maintenance Battery with Acid

    YUASA No Maintenance Battery with Acid

    Tom in ME

    It's a fine product.

    Original Yuasa lasted 6.5 years. This is dead as a doornail after sitting for two days after its first ride. It worked after the ride, maybe it needs a tender at all times.On the tender, needs a miracle. It did charge enough to make a click, then nothing. Battery seems to really like the battery tender to stay charged. Will update as time passes. I was reluctant about the acid coming separate, but all well. And the price is right. Would I love to have a $200 battery? Not $200 worth. If you do not have e-start, I'm sorry.

    Battery leaked, i couldnt verify if it was a sealed battery from the details. Battery seaped acid from breather. Ultimately lasted 1 year or less. I should have returned it and purchaed a sealed unit.

  • Ballistic EVO2 Battery

    Ballistic EVO2 Battery

    Phil in IN

    Great Battery - major change from the lead junk

    Works great, the only issue I had was the smaller size - compared to the original overseas junk (I ALWAYS BUY MADE IN THE USA - WHEN I CAN - too bad I ended up with a KLR for the commute to work), called you guys - came up with the solution of my manufacturing a hardwood spacer (or shell) with vent holes for heat reduction. Also I will add baffled plastic around the Blallistic battery to cushion it - that should do it. VERY HAPPY with your produces and Website.
