I'm also experiencing battery issues. I have a vex fl18, but where I'm seeing more of a problem is with my hummingbird 587 ci hd di unit in the boat. I had a 7ah vex battery I was using that wasn't cutting it, so I bought a Leoch 9ah from national battery in kingston less than 1 year ago. At first the battery would last all day, and I always charge immediately after use and often leave on a trickle charge. Battery is used every weekend all year long (pretty much). I also have issues with batteries I use for the trolling motor. I have a 50lb thrust motor, and I bring 2 large (27 and 29 group) batteries out everytime I go fishing (8 hours or so) and end up killing both. I charge them up religiously after every use and also keep them on a trickle charge often. The 29 group deep cycle is also a national battery brand - its on it's first year too. It used to last all day, but not anymore.
I have to think battery maintenance is playing a role here since both batteries bought this year used to last all day, and no longer do...I'd be interested in hearing what others' do for battery maintenance as I'm really having a hard time keeping power to my gear all day!
What do you guys think...need a better charger? Don't charge 'till dead? The small batteries are just charged with the vex wall-wort deal and the deep cycles are charged with a canadian tire 2-4-6 amp, usually use the 2-amp setting
Hey Dave
try turning the backlight down on your HB, as you know I use the same battery set up as you and mine was set at 10 and I was noticing after a long session it was almost dead, turned it down to 5 and it is still bright enough and no problems with battery life.
As for your TM battery my suggestion would be to not have 500lbs of gear in your 14ft boat and it would be less taxing on the TM
