Good morning everyone. My Auxillary
Battery in a Prado needs replacing. Talking to an Auto Elec yesterday he recommends a replacement with a Marine
battery. They are more expensive but according to him are a far better option. Can anyone advise me on a suitable
battery. Does it need to be a Marine
Battery? Thanks guys.

Our auto electrician does a lot of travelling, camping etc & he uses Bosch marine batteries as auxillarys. I think he quoted me around $210.00, as I am due for a new one in my Prado before our next trip.

And that is what the local auto-elec told us, very happy with the marine batteries now in our van and for the ute auxilliary.
The Bosch cranking
battery has been great too as leaving the lights on is a perennial problem with our LC VJ79, one time over an hour and she still cranked over to start
Cheers, Col

Without taking it out its damned hard to See what brand it is. If you were sitting in the drivers
seat it I located at the front on the right side.I think it's seen better days and needs replacing. Thanks johno

Hi Johno, I went through this dilemma a few years ago and ended up with a Century 100ah "marine "
battery. My aux is in the tray behind the cab and unfortunately it wasn't a good spot for it. Seemed to leak a bit of acid.I wondered if it was getting too much movement even though it was strapped down into a fixed
battery box.I didn't get a good run out of it for various reasons and have replaced it 3 weeks ago with a deep cycle
battery. When I did some googling on the subject I found quite a few references to the Century brand "marine" batteries leaking. You may be ok if its under the bonnet but something to consider anyway. Doc.

Apparently marine batteries are constructed to be much more resistant to vibration and shock than a standard automotive
battery, so they will last longer in a 4WD that goes offroad.

I contacted Century and they said just get standard 4wd
battery that is designed for vibrations and heat .I ended up buying 105ah 680cca Supercharge Allrounder deep cycle aux and for cranking 810cca Supercharge Gold.$380 for both.Gives me 210ah plus can use both to start or power my winch.

I have marine batteries for both cranking and auxiliary in my 120 series Prado. Both have given good service over ~4 years to date, including some offroad. In my opinion, if you plan to take your Prado on to corrugated or unsealed roads or tracks you would be
well advised to install a
battery that is more robust than the standard one.

Marine batteries are similar to cranking batteries, the big difference is the handles. The better AGM batteries are fine in off road use and supply more cycles.

You know,
battery manufacturer's and dealers must be plain stupid.
It is clear from the comments made here and elsewhere that "Marine Batteries" are the Antz Pantz for duty as auxiliary batteries in the off-road application.
So why don't they market the "Marine
Battery" as the be-all and end-all for off-road vehicles? Just put on a different label.

Exactly Allen B .I just replaced 2 batteries that were in vehicle for 6years.Normal lead acid made in Thailand.The previuos owner was builder in outback so served him
well.When I went to replace them
battery dealer told me to go same but the aux
battery 105ah and able to start Hilux if needed .I wanted AGM at higher cost but they said waste of money ..Before that I contacted Century asking them about Marine
battery they told me to buy normal 4wd
battery as designed for under bonnet and vibrations...cheers

Funny how an auto lec would say an AGM batt would be a waste of time ??
If you were using the aux to say run a fridge regularly overnight ( or longer ), then the AGM would be a no brainer long term.
If your use of the aux was infrequent, then a "normal" 4wd type
battery would give many yrs of service.
Some auto lecs and batteries just don't seem to mix at times ??

I agree Gronk that some auto elecs don't understand the applications but he's right when h says agms don't like sitting in the hot engine bay under th bonnet

He didn't say anything about AGM's and heat under the bonnet.
But yes, they don't like that environment. I was probably thinking the aux was anywhere but the engine bay ??
So, back to a deep cycle wet cell........know a fair few with the Supercharge deep cycle and are pretty happy with them !!

"funny how an auto lec would say an agm would be a waste of time"
the vast majority of Prado owners would put their
battery under the bonnet - not the best spot for an agm - this is the point the auto elec was clearly making - not funny at all

Don't forget the Redarc BCDC in the dual
battery system. Magic piece of kit.
