sneak_e_pete Posted May 26, 2014 Report Share Posted May 26, 2014 So I dont hijack the other thread.... Heading on a fly-in at the end of July and would like to bring my sonar to help learn the lake. Have a Humminbird 500 series (dont exactly remember model right now) black and white unit. Really want something inexpensive as this will likely be the only use for it and need it to be chargeable. Not planning on running it all day...just to find structure to fish. Thanks in advance! Link to comment Share on other sites More sharing options...
bushart Posted May 26, 2014 Report Share Posted May 26, 2014 If your biggest concern is weight---I knew a guy who used to haul a small 12v motorcycle battery on trips-----not meant to drain and charge all time---but for a short fly in---may get ya by Maybe somebody else here has tried them can chime in---I never have personally Link to comment Share on other sites More sharing options...
Sinker Posted May 26, 2014 Report Share Posted May 26, 2014 Go to an electrical supply shop and get a 12V Gel Cell. Rechargeable, cheap, and very effective. Should cost about $25. S. Link to comment Share on other sites More sharing options...

sneak_e_pete Posted May 26, 2014 Author Report Share Posted May 26, 2014 One more question...can you charge a gel cell with a regular battery charger? Link to comment Share on other sites More sharing options...
davey buoy Posted May 26, 2014 Report Share Posted May 26, 2014 One more question...can you charge a gel cell with a regular battery charger? Not the smaller ones I believe.They sell you a seperate charger color coded readout and tells you what state it's in. Link to comment Share on other sites More sharing options...
BillM Posted May 26, 2014 Report Share Posted May 26, 2014 One more question...can you charge a gel cell with a regular battery charger? Whats a regular battery charger? Like a Battery Tender or similar? If so, then sure. Link to comment Share on other sites More sharing options...
Sinker Posted May 27, 2014 Report Share Posted May 27, 2014 I charge my gel cell with my deep cycle charger, and have been for 5 or more years. I cant believe it still holds a charge....i use it in the boat and on the ice. Just use the lowest amp setting. S. Link to comment Share on other sites More sharing options...
adempsey Posted May 27, 2014 Report Share Posted May 27, 2014 The 12V AGM SLA battery is the ideal choice. However, if you need to, you can use 8 AA- or D-cells [or two 6V lantern batteries]. Might consider installing an inline fuse as well if it's not a portable unit. I can't say how risky it is without it, but the manual will indicate you need a 1A or 3A [or XA] fuse between the battery and the unit. For my soon to be portable sonar, I picked up an inline blade fuse holder and some 1A blade fuses from Canadian Tire for a few bucks each. I will hook that up to an AA battery pack and will be using rechargeable NiMH batteries. Haven't put it all together yet though. Of course, I may not even bother with the AA batteries because I am not sure it's even worth it just to save a couple of pounds. Link to comment Share on other sites More sharing options...
Old Ironmaker Posted May 27, 2014 Report Share Posted May 27, 2014 I have a 19 year old Eagle Ultra 2 portable that has two 6 volts that fit in the box it's mounted on. Lasts an entire week of 5 hr days on 1 set of batteries. Still have it and still works I think. It's b&w, I think the coloured screens with loads of info on the screen kill batteries faster. Yes, no?

porkpie Posted May 27, 2014 Report Share Posted May 27, 2014 I run a colour humminbird 597 off of a 12 volt gel cell battery. I just find it easier to keep the bird on its own battery in the boat, and the gel cells weigh next to nothing anyhow. My unit will last a couple of trips on one charge. It's probably the best way to go! Link to comment Share on other sites More sharing options...

Fisherpete Posted May 27, 2014 Report Share Posted May 27, 2014 I was at SAIL yesterday and they have a Humminbird 12v 7a gel cell battery & charger kit for $60. I think Lebaron carries the same kit. Your 500 series Humminbird will last a long time off it, I ran a 525 with the same battery and used it for four or five long days of fishing before charging.

adempsey Posted May 27, 2014 Report Share Posted May 27, 2014 My HB565 portable runs for about 40 hours off a 7AH 12V SLA AGM. I had to replace the original battery and purchased a 9Ah battery instead which gives an additional 10 hours. I actually had a lot of problems with the various 7Ah batteries/chargers that I bought. No problems when I switched to the Vexilar branded 9Ah battery/charger combo... so far. Link to comment Share on other sites More sharing options...
