Optima batteries

[Tightline11]

I had a set (3) of batteries on my boat that were from NAPA and they were deep cycle batteries. Trolling motor was slower than normal took all batteries to NAPA had them checked and it was one that was bad. The batteries were dated bought in 2006 which was what the white writing was on the batteries. Left NAPA with one battery cause the salesman said the rest were good. These batteries stay on a battery maintainer at all times and have lasted this many years and have never went dead on an all day fishing trip. Just giving you my experience with NAPA batteries and the cost is not bad either right at 90 dollars.
