Does any one else find the new Humminbird Onix 10" slow to boot up (1.5 minutes)? I have the biggest blue top battery that you can get and when running both of my 10" humminbirds (1197 & Onix), they would ran my battery down to 9.4 volt after 4 hours. Got the battery load tested and it is fine. It would interesting to here from other boat owner inputs.

Thanks
Chris

The ONIX 10 takes a 5A fuse and the 1197 takes a 3A fuse. That should give you an idea of the power requirement difference.

Yes the ONIX takes a while to boot up, it does a lot of stuff. Notice how much thicker the unit is than the 1197? The mapping card makes a difference too. One of my 1198's has a Navionics Platinum card and the other has a Navionics Premium. The one with the Platinum card takes longer to boot up.

You need a better battery with more reserve capacity than a Optima for starting/deep cycle or a true deep cycle battery if the units are the only load.

I run Deep Cycle batteries and have no power issues.

Do you have a fifth battery for your electronic only? Or you saying to use a deep cycle battery for my cranking battery ? The blue top battery I have is the largest reserve capacity optima made.

Thank you for your input Wayne.

Yes, when I fish electric only waters, I use the group 24 DEEP CYCLE battery for the ONIX and 360 only. I use two group 27 batteries for my bow 24V motor and two group 27 batteries for my transom 24V motor.

When I fish waters using my outboard, I use one of the group 27 batteries for engine starting and the electronics and the same two group 27 batteries for the bow trolling motor.

For several years, I used a 36V bow trolling motor and that involved another group 27 DEEP CYCLE battery.

The BRAND of battery you are using may be the issue. Get one that can handle the task, obviously the one you have cannot. What a lot were doing with the issue you have if they have a large outboard is use a Sears PM-1 size 31 which is a Dual Purpose for starting and deep cycle use for electonics, pumps, lights, etc. That battery is no longer available so a similar one is used OR two batteries parallel for the task.

This is my setup when using the outboard:



That lake is why I changed to a 24V bow motor to lighten the boat so stumps would not be as much of an issue.
There are thousands just below the surface. Been getting hung up on them for 20+ years.

One more thing is the power connection you use for the units. Each power cord should be extended directly to the battery with at least 14 gauge for the 1197 and 10 gauge for the ONIX. If you used the boat wiring harness, that is typically not enough for the load over distance. It's that resistance thing.

To run your Onix 10 and your 1197 at the same time your power draw will be aprox 3.8 amps (depending on brightness settings) If you intend to runs this setup for 10 hrs on battery only, you'll need a Deep Cycle battery or batteries in parallel with aprox 82 Amp Hrs of storage. The amount of discharge you draw this battery setup down to will greatly affect the total life cycles. The farther you draw it down the fewer the cycles. There are a lot of batteries out there that are not worth buying and doing your home work up front will save you $$ and a lot of headaches.

Wayne and Pelican,

Thank you both for your inputs. I have a 225 verado outboard that required a 1000 cranking battery. What I have is a Optima Blue top D31M (cranking and deep cycle) battery for my Motor, livewells, and electronic. The Onix is wire directly to the battery with a 10 gauge wire. The battery have a 155 minutes reserve capacity (25 amp discharge). Sound like the both of you have do some research on battery. Could you please let me know with brand of battery works best for your both? Again, thank you for sharing you input with me.

Best Regard
Chris

AA93, I fish from a kayak 95% of the time running a HB 999 which pulls just under 1 amp so I'm battery only, no charging system. Prior to getting the 999 I was running a HB798 so I've been fighting this problem for about 5 years. One of my problems has been the weight of a lead acid battery or batteries that are big enough to run my set up 12-16 Hrs in the summertime. The other big problem for me has been getting enough charge/discharge cycles from the batteries I've tried. I have yet to find a battery that will last me more than about 10 months and I never discharge below 12 volts. A big part of this was caused by not using a high quality battery. Some of the higher quality batteries that I have researched are names like US Battery, Concorde, Crown, Rolls and Trojan, there are several other companies to consider. These batteries are not cheap and the flooded lead acid is the less $ than the Gel or AGM.
I finally decided to go with a StarkPower 12V-30Ah Lithium-ion battery and so far have been very pleased with this choice.
With that said this battery was VERY expensive and probably not a good choice for most people but it solved both of my battery problems. This is a true deep cycle battery and not to be used for cranking.
Being that you are fishing from a boat I think your issue will be much easier and less $ to solve.
I'm sure Wayne P will have more useful information.
