How Long does battery last in hand held on co pilot?

I have had Powerdrive 12 volt v2 with co pilot for a couple of months now, and been Long lining and trolling cranks about 2 months. 15 minutes into trolling crank baits, motor would spin and only way to stop it was un plug it and then plug it in and start moving again and it did it a second time freaking me out alittle as well as tangling lines up, figured it was battery getting weak so switched remotes as I had a spare, and it never did it again. Both hand helds are brand new, so just curious as to how long the batteries last as I will change them out, carry small screw driver and spare batteries with me also, I figure I have used the remote about 160 hrs or so.

Don't think that was your problem. That usually happens when it looses it's GPS signal. Mine is 4 years old and still going. Carry a spare.

I have only changed mine one time in six years.....I carry a spare also. I agree with cray you temp lost your satelite signal for gps

Anyway to avoid this from happening again? Or should I contact min Kota about this?

Not really....can be caused by sun spots or cloud cover.....Mine has only done it one time in six years.

Mine did it 3 times this morning over a 400 yd. run trolling bandits in the middle of a 1700 acre lake. Bright sunny morning and I have run the same line a dozen times in the last 3 weeks. Trolling motor wanted to completely go round and would have snapped the wiring if I hadn,t quickly unplugged it. All happened in 15 minutes. When I swapped hand controls, never happened again over next 4 hrs. Really screwed up mess for about 20 minutes. I had fishing lines and bandits rapped around trolling motor and the big motor prop at the same time. LoL. Had to unplug the motor 3 times as had absolutely no way to control it from the hand held control.

Change the battery to be sure. I've seen all kinds of brand new batteries bad fresh off the shelf.

My guess is a stuck contact inside the remote. As far as I know that remote only sends a signal to the board and yours kept sending a signal. It could be a corroded contact inside the board of the TM but then the other remote should not have fixed the problem.

I have v2 co pilot remote and a spare remote. They are both 7 years old and still work. Not used much though.

My Ipilot remote was 5 years old when I sold my War Eagle. I keep spare batteries in my black Crown Royal bag that I carry the remotes in. Billbob gave me the bag, so it is a special bag to tote stuff in.

I have changed the batteries once in about 5 years...and I fish....A LOT. You have something interfering with your signals.
