battery ?

[jhef]

need a battery for a trolling motor only project, motor is a 55 lb endura max , wot is 50 amps ..looking at batteries and some have the reserve minutes some just have the amp hours...im thinking reserve minutes is the best to go ..so say a battery with 200 reserve minutes divided by 50 amps= 4 hours of running at full speed???/ right? just dont want to paddle ...am i on the right track...so far i found a duracell ultra for 99. bucks it has 225 reserve minutes ..

That Duracell with 225 minutes reserve is at 23 amps.

ok academy exide stowaway battery 182 reserve minutes 105 amp hours at 20 amps.. my trolling motor at max pulls 42 amps.. so double the 20 amps so are they saying this battery will last 52 hours or so pulling 40 amps? if so i call bs...ive seen some batteries with amp hours showing some with reserve minutes but this battery shows both lol... just want to fish all day with no worries and having to baby the throttle on my troller

With 20A load should last 5H 15M with 40A load should last 2H 35M...Thats on paper..Realistic probably 20% less.. Just been rough numbers from my exp.
