997+787=dead battery
Guys, I sent Greg at Hummnibird an email on this but I wanted your thoughts. Yesterday was my first full day I had to go out with my two new toys...a 787 and a 997. Both are linked to the same battery. After 4 hours I got low voltage warnings on both units almost simotaneously. Shorty after that both units shut off. When I got home and put the charger on the battery it was, indeed, low. Do these units draw too much power to have them on one battery for a full days fishing or could this just be a bad battery?

Brand new battery...new onboard charger. I charged all 3 bats (battery in question plus 2 trolling motor bats)the previous evening and had a green light on all three when I unplugged the charger.

Cane Pole: Im not sure I understand you question. I'm new with these units. Whatever the alarm voltage is would be what it is set on when it came out of the box which I assume to be the default setting. How do I check this and what do I change?

Carp,
I have the exact same setup as you. I also have an interlink box connecting the two units together. I also fished yesterday from around 7:00 to about 4:00 in the afternoon running both units all day. It sounds like you have a bad battery because when I came home I hooked my battery charger up and only took about an hour and a half to top the battery off. (@ 2amps) The same thing was happening to me with my last battery which was practically new but since I exchanged it, I've had no problems at all.
Hope this helps.
