Re: Looking for a non bulky 12v battery for my MB
12 volt, 7 to 10 amp hour batterys are the way to go. They're small, easily mounted, rugged and will give you good light for well over an hour. Recharge with a small trickle charger and you're ready for another night of cruising. I did learn something from an engineer from a major battery manufacturer. He said mounting the SLA (sealed lead acid) style on their sides and subjecting them to vibration and shock can shorten their life. I mount all mine vertical and have no problems. I typically run a 30 watt sealed beam headlight and one bike has a 55 watt.
