Save me some money and educate me.

I was told by an old guy that knows just about everything that 2 years is about it on a trolling motor battery so i figured my casual approach was OK.

Same me some dollars with some advice.
You need to recharge the battery as soon as possible after a discharge. This will help prolong the life of the battery. Also, as mentioned earlier check the water levels. Put some of the Minn Kota Battery Equaliser fluid in for good measure.
