Looking to see if anyone knows a part number to get rid of the cheap battery that comes with the coolster 3125r atv it is the 125cc. Looking to find a replacement battery at a local store like walmart or part store if possible. Any help would be greatly appreciated.

 

Part of this may have to do with space allowed,but shows to be a 12v 5 amp battery like on most Chinese/Taiwanese machines.Battery An upgrade would be to a Yuasa as these are what Polaris used on their youth models and are good batteries. If you could fit a slightly larger amperage battery that would possibly even be better. Make sure your charging system is up to snuff also and not the cause.Yuasa YTX5L-BS AGM Fresh Pack 12 Volt Battery YTX5LBS | eBay

 

If it fits, get one or 2 ub1280 AGM batteries, the kind that is commonly
used in burglar alarms. I get them for $16 ea online, and just installed
one in a Kasea 125cc GY6 buggy. More than enough juice to power these
engines (8 Amp-hours). I also used them in several Coolster 250cc
buggies.
