Ulterra draining batteries

[Grumpa]

Does anyone else have that problem? I have an 80lb 24V and the batteries only last a little over3 hours. They are less than 2 years old. I think they should last longer that that. I was mostly spot locked with some wind but not what I would call heavy winds.

Are both batterys the same group size and the same age ?

I have the same TM and have no battery issues. I'm running 2 grp 27 batteries. I can slow troll all day on a full charge. If just using spot lock I can go 3-4 trips without recharging

You need to pull batteries and have them load tested. Have you checked the water in them? Something wrong like a bad battery drawing other one down.

Thanks for the replies, both batteries are the same size and age, they were bought in the fall of 2018 and are always on a charger if not on the lake. I will have them tested. Thanks

Check the water...charge them....then load test them

How are you using the motor? Continuous or on/off?

I have 80lb Terrova and use fastest setting moving between spots and occasionally to use side scan and have no battery issues. When was the last time you serviced batteries? I had a similar issue several years ago and discovered that my charger was only charging on 1 circuit to trolling motor batteries.
