Cranking Battery

[TNBronzeback]

So i guess last time i was out a few weeks ago, i must not have turned off the Master Power switch and something must have been left of. Anywho, dead cranking battery.
I took it out and charged it till my charger read 100% and shut off. Re-installed battery.
Got to long hunter sunday morning and upon lowering the motor, i knew it didnt sound right. Sure enough, that all famous "click" when i turned the key. No biggie, i took a trolling battery, swapped it and no problems.
Got the cranking battery out and its in fact a Deep Cycle battery.
Any reason why it would be a deep cycle as opposed to a cranking battery? Console Garmin and everything on the dash runs off that battery, lights, livewell, ect. Is that why its a deep cycle?
Im guessing i should replace it with another deep cycle?

I think with to days electronics and starting needs I would recommend a dual purpose marine battery. Here is a quick google search. I hope this helps.

Defiantly Deep cycle with everything you are running off of it and like AlanRay stated Dual purpose for a single battery ... In fact I would run two batteries in parallel if you have the room ... Same voltage but doubles your amperage (staying power).... The best battery for the money are Walmart Batteries ... They are made by Johnson Controls, when I was guiding I was sponsored by a number of Battery Manufactures but These batteries gave me the best performance with a good warranty... Just my opinion ...<'TK><:)

Thanks guys.....i will certainly look into fitting 2 batteries in there. Deep cycle.
Random follow up question....my TM is a 12 volt but im running 2 batteries in tandom.....if i could fit 3 batteries in there, would that work or would it put too much strain on something electronically?

Google search the difference between wiring your batteries "parallel" vs. "in series". Heck - Here is a quick link to save you the search. https://www.batterystuff.com/kb/articles/battery-articles/battery-bank-tutorial.html

If you wire them up parallel, you could have 75 batteries in your boat if they would fit and it wouldn't hurt any of your electronics. Wiring nmultiple batteries together parallel doesn't increase your voltage. It's kind of like making 1 HUGE 12V battery if you wire it up that way. However, if you wire 2 or more 12V batteries in series, you'll damage all of your 12V electronics, including your trolling motor as each battery you add increases your overall voltage by an additional 12V. Putting 24,36,48 etc volts to your 12V electronics will ruin all of them.

Hope this helps!

JK is correct... Now, what he didn't say is when you run batteries in series (Like a flashlight) your' increasing your voltage by 12 VDC for every battery added but you are also reducing your amperage (staying power, opposite from parallel) .. I had a 24 VDC TM ... I ran four batteries.. two in series to achieve my 24 VDC and ran two more in series and then paralleled them for staying power .. I also ran three batteries in parallel for start/on board electrical and electronics/and a large bait tank .... 12 VDC....almost tripled my amperage ... <'TK><:)
