When it's time to replace your Yamaha ATV battery there are a few things you'll need to know. The model and year of your Yamaha ATV are usually enough. It's not a bad idea to have the serial number handy just in case there was a mid-year change.
If you're not sure of the model and year you can look at the battery and note the model number on it. It's always a good idea to measure the battery so you can make sure it will fit. Don't forget to check which side the positive and negative posts are on.
These days you'll have a choice between a conventional water filled battery and the newer maintenance free sealed batteries for a few dollars more. We like the sealed batteries because in case your Yamaha ATV gets in some position other than rubber side down - they won't leak acid like the regular batteries would.
The best deals we've found for a Yamaha battery are at Ebay Motors. You can find just about any battery you want there. We have tried some of the cheaper imported batteries (Chinese) and they may be OK for light use. But for the way most of us ride our ATVs - we think it's a better idea to stick with the name brands like Yuasa.

For the longest life from any ATV battery we recommend one of the "smart" battery chargers. They all work about the same way.
The main thing is to keep the battery charged to peak capacity instead of letting it discharge to the point that it won't start your ATV. Every time a battery discharges it shortens its' life.
We promise you a charger is one of the best investments there is. The Battery Tender brand is the most well known but there are others on the market now too. Check 'em out at the link below.
