Motorcycle Batteries and how they affect powering accessories?
Question by baggermike: Motorcycle Batteries and how they affect powering accessories?
Hi I have a bike that I am having a little problem with it powering my heated gear, the bike is rated at 432 watts at 7000 rpm and is a 3 phase 32 amp charging system, but the bike has a 10500 rpm redline and 7000 rpms at cruising is not good and around 4000 rpms feels good for cruising and on the hyway at 70 mph it is running at 4300 rpm so I do not know how many watts are being gennarated at that rpm, is there like a formaler to calcalate watts at that rpm, I have a program that you can put all the power the bike uses and with my heated jacket and gloves I have 35 watts left over. The battery is small and is rated for 200 cca and 12 amp hours, I can get a battery that has more power but do not know the benafites of the battery that puts out 250 cca and 18 amp hours, and if that would make the voltage regulator work more to keep it charged or hurt it, and only know that more amp hours would heat my gear better, so any info would help me allot. thanks Mike

Your battery is a storage vessel and matters very little while the engine is running.
So long as your charging system puts out enough juice, you don’t need ,nor will you benefit from a hotter battery.
The advantage to a more powerful battery is that it will turn over higher compression motors. ( cold cranking amps )
