What if I use a 24V 100W Alternator to charge a 12V 36W battery?

I'm trying to figure out a power source for the lights on my MB. I found a 24V 100W electric motor that will be turned by the MB Engine, then used to charge a riding lawn mower battery (12V 36W), will it charge it correctly?


I'm running 12 V lights, and all together 8 Amps. I'm actually using a Motorcycle battery, which is 12V 26W and 8.6 Amps
