new charger, on board or external ?

[capt charlie's charters]

so its looking like my 2002 3/bank Triton charger maybe causing my battery problems, okay 14 years old and a beating on the waters, maybe its time.

I've warranty replaced two cabela's AGM's ( trolling mtr ) over the past two years.  toward the end of the season I'd hit the water and be like on low juice right from the get go even though the charger indicated green, charged and when pulling for the winter there was a white powder from one of them ( again trolling mtr ).

so the $64 question, ( okay so they cost more then that ) go "on board" or like more are doing go with an "external" ? and what brand ? what model ?

my fishing is down to maybe once or twice a week in the summer, two to three road trips involving 3 - 5 days on the water.  maybe once or twice in april and again in may.   2 - 3 times in oct, once or twice in nov.

I've been very happy with my Bass Pro Shops on board charger. It's a little slow, but charges my mix of traditional deep cycle and AGM batteries without issues.  I do have a Battery Tender external charger that I use for the spare battery and off-season maintenance charging which has also worked really well.

I have an on board charger and I am going on my 2nd season with it.  Before I toted around an external and really like that the onboard is always there and ready.  I can not say much on brand preference but I have a MInn Kota 315D and it seems to do a fine job, the batteries are always charged the next day.
