Default Do all ATV batteries have the same cranking amps?

When I buy a replacement battery for my sled or ATV I just measure the dimension to make sure it fits in the battery cage and off I go to Wall mart. Both my sled and ATV are easily pull start with one hand however.

My friends 660 Grizzly with no decompression and almost takes two people to pull on the rope handle to turn it over needs a battery now.

Would a ATV like that need a battery with more cranking amps ?

I never paid attention to cranking amps on these small batteries like I do with automotive ones.

Well I do know you can get 12v batteries in different amps for 'powersports'. Weither or not they would all fit in the quad is another matter. How many amps is his current battery?

Batteries for different ATV's are indeed different capacities.

The stock battery for a 500 Foreman FM is rated at 12 amp hours and 200 cold cranking amps, and the stock battery for a 680 Rincon is rated at 18 amp hours and 250 cold cranking amps, for example.

Regarding amp hours, if a battery can deliver an amp of current over one hour, then it's capacity is 1 amp hour. Since a battery will deliver more amp hours if it is discharged more slowly, amp hours are rated on a time scale.

Starting batteries are generally rated on a 4 hour scale. A 20ah battery would deliver 5 amps for 4 hours before being fully discharged (down to 10.5v). RV batteries are generally rated on a 20 hour scale.

Battery type is also an important consideration. The stock battery is an AGM type, for absorbed glass mat. Cheaper batteries are often flooded cell.

Compared to flooded cell batteries, AGM's have a longer service life, resist freezing better, resist vibration better, and most AGM's can be run at any angle and won't spill if tipped or even if broken. Flooded cell batteries often require a vent hose in motorcycle applications....


Bottom line, unless you are really broke, I'd go with a good brand name AGM of at least the amp hour rating of the stock one.

I saw a thread somewhere that Honda had a part kit for a bigger battery that will fit in the Rincon that would improve starting in extreme cold weather (like Alaska in the winter). Yuasa apparently builds a battery of higher amp hours/cca, but the terminal locations are different, so the kit comes with longer battery cables...


You may be able to find a larger capacity battery that will fit in your battery compartment by browsing through Yuasa's web page.

Thanks for the battery info, we went to this site found this Yuasa,s for a 660 grizzly

They state

<div class="FTQUOTE"><begin quote>This is the High Performance version of this battery offering a whopping 310 CCA. </end quote></div>

So the it has 310 cranking amps I guess.

I quess I was just getting lucky at Wal Mart when I just bought the cheapest Battery that had the correct demention. They all had the vent hose BTW.

Will stay away from those kind from now on .

Thanks.[img]i/expressions/face-icon-small-smile.gif[/img]

Looking in their application guide, it looks like a SP 500 takes a YTX14AH-BS, and the YTX20HL-BS isn't much different, size wise...

It looks like it would also fit in a Rincon.
