my dad used optima batteries in his drag cars (ignition, fuel pump, water pump, gauges ect.) and always had to put the charger on the batteries between runs. otherwise the batteries would die before the end of the day. i always used interstate batteries in my truck and boat and talked him into switching batteries. the interstates would last a whole day of racing without needing to be charged. i run my 46# trolling motor, fish finder and lights off of 1 interstate and can fish all day long without losing power. sometimes i would forget to charge the battery between fishing trips and still be able to fiah all day. and they are under $100. this is just my opinion, but i think optima's are way overrated and their prices are just rediculous.
