what batteries to get and where

[JUST-IN-TIME]

difference between a car battery and a marine battery
is the cold cranking amps (CCA)and size of the plates and outter casings
marine CCA is at 32F
car is at 0F

DEEP CYCLE vs CRANKING
cranking batters are meant to give a short burst of amps
deep cycle are meant to give low amps for a long period of time

also deep cycle casings are taller, due to the fact they can go dead and be recharged, do that to a starting battery and u will kill it

for anybody who owns a boat and only has 1 batt, invest in a switch and another, or at least have a jump pack


2 good readings

oh
1 more thing
with optima batteries, once a cell breaks down it is dead
unlike flooded batteries which u can replace the water in it

i also noticed optima need a charge more and lower amps

I with ya on the extra battery. It’s just such a small expense for the added peace of mind. We chill out in the middle of the lake listing to tunes and with all the extra power demands of ballast pumps, bilge pumps, audio amps and such a single battery just doesn’t cut it anymore.

i got alot of helpful info from this thread, but are to marine cranking batteries deep cycle as well? I'm confused that if i get a cranking battery on a perko off, 1, 2, both switch w/o an isolater if 1 goes dead i cant start with 2. is that right?

[WakeSlayer]

as I have learned from this thread: Marine cranking batteries are cranking batteries, not deep cycle. They have extra terminals and a handle.... Functionally, they are the same as auto cranking batteries with a couple little features, and a heftier price tag. Deep cycle batteries are completely different. I will leave the rest to the electrical guys.

I find it funny the guy who posted the thread is still confused.

[gride300]

you mean you find it funny i'm still confused? I did alot of reading on the links but i'll just call secc tomorrow.

[WakeSlayer]

I think I may be un-confused now.

[jaybird]

Can anyone say TO MUCH INFORMATION ! LOL But yes if you have a switch with 1, 2 or both you can switch to both and crank if you kill one.........
I think we have exhausted this thread......

only 2 types of batteries

CRANKING or DEEP CYCLE, then the marine vs auto

DEEP = long drain little amps = stereo
CRANKING = short drain ton of amps = starting a motor

isolators or crap!!! get an acr switch, blue sea system sells them

[jaybird]

Now guys you know either deep cycle or starter will start you engine fine, if the deep cycle wont start your engine you need a tune up........ And no better money spent than a charging relay if you have two batterys. And Blue Sea also has them too..................
I vote we kill this thread

[Chris4x4Gill2]

someone want to explain the difference in an ACR switch VS an Isolator now?

[JUST-IN-TIME]

ACR vs ISOLATER

isolater will charge batteries even though they do not need it

ACR is an electrical switch, it senses what needs what and sends it to them

[hyperwake]

So after all this anyone have a recommendation on CCA or CA for an 01 SAN? I need to replace mine also. When I bough the boat it had a Deep Cycle and a Cranking set up with a perko switch. I dont like it and want to get 2 new batterys.

No problem Andrew, you must be Ok if you’re from Alabama and a Nautique fan :-)
Its just a bit insulting "everything jaybird said is horribly wrong" after 30 years of electrical engineering design I would like a wee bit of respect.
I’m just trying to help a fellow Nautique fan so lets keep this civil and not personal.

I just wanted to make it clear to anyone reading that they should never connect 12v batteries in a series circuit when ALL of their electrical components are 12v! Your "helping" could have cost some poor reader quite a bit of money in damaged stereo equipment! Unless my reading comprehension is rusty, you have gone through some sort of double talk throughout the entire thread.... I won't even bother pointing out the errors in that post, because you have already done so in some confusing 'round-about way :???:
