For FishingMagician.com, I'm Eric Granstrom. On my last few trips out with the boat, I've noticed I've had to crank my bowmount trolling motor up a few more notches to maintain a proper trolling speed. I began to worry that it might be malfunctioning. But then I noticed a different colored indicator on my trickle charger for the batteries serving the bowmount. After checking the connections and making sure they were corrosion-free, I began checking dates. Sure enough, the deep cycle batteries were about two months past their 36-month life expectancy. My downriggers were also starting to sound sluggish on the return and checked the batteries in the stern serving them, and the batter was 3-years past its due date. Anyone who's purchased deep cycle, RV batteries knows they're not cheap. Much to my chagrin, I had to replace all four batteries in the boat. Now, the wiring hookups at mid-ship and in the stern were not my doing. One tip I'd suggest if you find yourself with a puzzle of wires is to grab your cell phone and snap a few pictures of everything and where the wires go before unhooking anything. Fully charged, I'm ready for more fishing. Until next time, Good Fishing!
