Question

What is the lifetime of a 12v battery if it is going to be used on a 30lbs thrust trolling motor?

Answer 1

I have a GM Deep cycle that is 10 years old and it is still going strong.  If you keep it clean and charged after using it, and bringing it in the house during cold weather.  It should last a very lonnnnng time.  I recharge and clean mine after every use, and in the winter I bring it inside into the basement and put a small trickle charger on it, it shuts down after battery is charged, and comes back on when it needs it.

Answer 2

If you are talking about how long will it run the motor on one charge, Divide the amp hours of the battery by the amps of the motor. The result will be the number of hours the battery should last.

If you are talking about the actual lifetime of the battery, there are too many factors involved for anyone to give you a correct answer.
