thanks ive seen that one but the ah on that battery is 12 the one the owners manual is 10 does it make a difference? also was told to get a yuasa battery

 

I was told by the bike shop and have since learned that Yuasa was bought out by another company. As far as the AH, 12 is better than 10 as long as it fits, and it should.

 

that amp-hour rating is simply that.. how mny amps per hour it will produce.
that batter can flow 12 amps at 12 volts for 1 hour, OR 1 amp at 12 volts for 12 hours..

no big deal.. never undercut yourself, tho.. treat that a/hr rating as a minimum rating for a battery.. then again, try not to exceed another 60% or so as you'll stress the charging system when the battery is a little low...

welcome to KF!!!

 

Car and bike batteries are usually rated at a 10 hour rate.

THat means that a 12AH battery will be able to deliver, when fully charged, 1.2A for 10 hours. If you try to draw 12A from it it will stop delivering well inside the hour as the battery becomes 'tired', although it won't have delivered it's full charge. After a rest it will be able to resume. This is because of the chemical acvrtivity wiothin the battery.

Starting current exhausts the battery very much faster. For a bike, look at the figure for cranking amps. This is a measure of how much current it can deliver to the starter motor and is probably the most important thing that you need.

Too big a battery, in capacity terms may not fully charge from the bike's alternator and there is a theoretical risk of damage to the alternator and regulator over time - very unlikely though, in the real world.


10, 12 or 14AH batteries are all good to use as long as they fit physically.
