Humminbird 859hd di and battery drain

Went fishing this afternoon and had an issue I never had.
After playing with my new terrova and down image transducer, I had a notice come up on the bird saying low voltage. I went and tried the motor and it cranked fine. Went back to fishing and it happened again. This time motor turned over and over but would not start. Then wouldn't turn over at all

Batteries were all fully charged. 1 is for cranking and electronics and live well ( it has timer). The other 2 are for 24 v terrova.
Just curious if y'all experts think the bird could have used that much voltage ?

Any and all suggestions are welcomed.

bad battery

I think you have a battery problem

Yep, what those two Geezers said!!!!!!!!!!

They're crazy you don't have a battery problem its the 859 I buy scrap depth finders give you $50 bill for it.

Sounds like a bad battery to me too. I've run two, and sometime three fish finders along with the live well and minnow well for hours and hours with no problem.
You know where the Exide place is in Pearl? That's what I use..

It's a 3 year old interstate battery. Gonna take a spare exide tomorrow. It's a 31 series and the interstate is a 29 series. Never had a problem before but I figured battery. Thanks for all responses.

Most local auto stores will check your batteries for no charge. They can test for battery drain, low voltage, and bad cells. The bad thing is most all marine batteries only have a 1 year replacement warranty.:twocents

Some batteries will get a memory to them as they age. You drain them so much each time you use them and then recharge. After a while when they get to that drain point they will act dead. Wire a light to them and let it drain completely, leave the light on it another 24 hours. Then put them on a slow charge for 24 hours or more.

Charge the batteries before you take them to an auto parts store. If they don't show a full charge when you get to the store you'll know of a problem. They will put a charger on them for testing.

A 3 year battery is showing it's age. The longest I've had a battery to last is about 40 months.
