| I have a question on one of my trolling motor batteries. How fast have you guys seen a battery go bad. Please bear with me on this. I put a 24 volt EM on my boat and ran it with no problem for the first two time out. Bought one new battery and left in one of my older batteries. The third time out the motoer would not run. I took it in and the repair center told me the armatur burned out they fixed it and it ran fine. I then figured I would replace the older battery with a new one. Now I have two new batteries about a month apart head out for a tournment first day motor runs great plug the boat in that night second day the motor is barley turning. That was the end of the season so the boat got put away until this weekend. So I was about to pull the motor off and take it back to the service center, but first started to play with the batteries, cleaned the terminals, charged the batteries, and figured give it a try, nothing. I noticed that the first battery I bought seemed to not be taking a charge while watching the meter on the charger. So on a whim I still had one of my older batteries charged that battery and low and behold the motor screamed to life. So my question is has anyone ever seen a new battery go bad after only two charges or could my on board charger have screwed the battey up? I do have two differnt series batteries, which I did by mistake. It is the smaller series 27 that crapped out. |

| If you let the battery get too low, some on board chargers will not charge them. You need to get it started with a portable charger, then plug in the on board. Sometimes this is all it takes, sometimes the dead battery cannot be charged. Sometimes you just get a bad battery, ot it gets damaged of broken during use. Boats are hard on everything, batteries included. Did you check the water level in the battery before trying to charge it? The plates need to be covered for a full charge.
I advise using batteries of the same size, but it is not a requirement. You battery life will basically be that of the smallest one, is the biggest deal. |
