Hey amigo, 9amphr battery doesn't have enough juevos for your HDS. I had to upgrade to a 12v 12amphr battery when I got my HDS5.

A good and fully charged 9ah (or even 7ah, for that matter) is plenty to run an HDS 5 for 8 or 9 hours OTW. The exception being the amount of backlight being used (.4a draw without, .7a with the backlight on). Like RedSled said, buy a $5 volt meter to keep tabs on your batteries instead of just relying on the color of an LED light. A fully charged 12v battery should show something over 13v on the meter when fully charged. For a 6v it should read something over 7v. If they will not charge up to about that, then either they are bad or your charger is bad. Once they are charged up, take them off of the chargers if you don't go out on a regular basis. Another big consideration is to make sure all your connections are still good and waterproof.

A good battery should last 5 years, don't let it sit dead and charge it at 1/10 the amp rating, that means a 1amp charger for a 10 amp 12 volt. Using a 2amp+ shortens the life of it. Your fish finder will likely shut down around 8 volts but your bait pump will run it all the way down.

Kinda figured that, I need to check the back light setting like Greg said, but I had a feeling about the 12amphr...thanks guys

mtnbykr2 I have been running 9ah batteries on my HDS's (both the 1st gen and Gen2) for 3 years now. The longest I've ran them was about 8 hours and they never quit. I never have my backlight on full though, around 6 or 7. Hope this helps.
