Buy one or two?
 

One of my 24V trolling motor batteries has died on me. Any advantage to replacing both, or just the bad one? Big Momma 27's both originally bought at same time.

Buy 2.....

It's a good practice to replace your batteries at the same time.

Costing me money!! Thanks

Mosslake, how long did your big mama's last? Thinking about getting Gel batteries from Academy for my trolling motor, they are on sale at Academy right now. Anyone have any imput on Exide gel batteries?????

Had looked at receipt the other day and seems like it was about 5 years on the first set. Actually only one is bad now, but i replaced both of them. Not sure if it was just coincidence, but the one that crapped out is the one I had my stereo wired into. Have an onboard charger that stays plugged in when not in use. For reference, just payed $125 each for the Big Momma 27 at Jerrry's Marine.
