The three common 6 volt flooded lead acid batteries compare as follows:
145 125 105 Battery (US or Trojan)
530 488 447 Res Min @25 Amps
145 132 115 Res Min @75 Amps
205 197 189 6 Hour Rate (AH)
71 66 61 Weight (lbs.)
10&3/8 same same Length (in.)
7&1/8 same same Width (in.)
11&5/8 11&3/16 11&3/16 Height (in.)
625 650 754 Lab Cycles
The numbers are about the same for the US Battery's and the Trojans. The 145's weigh more, are taller, have more capacity, and have a shorter cycle life.
Which is best probably depends on the range you need. I am currently using the 145s but I may switch to the 125s for my next set. I went with the 145s because I was not sure my truck would have enough range with the 125s.

Lawrence,
The US 145s are slightly taller. When I did my calculations a couple years ago I came up with a better power to weight ration on the 145s than the other models. I also concluded they had a lower internal resistance and better peukert. I think the later was something that was based on reading the US literature but I don't remember now.

I saw on the US Battery website that all their 2200 thur 145s have the same case. There is an eleven pound difference and greater amps in the heavier units. Do the heavier units also last longer? Is there one model that has the longest life? There must be some reason for the slight differences. They must save money by using one case. I am interested because I need to put batteries in the Laher. Lawrence Rhodes....
