Auxiliary Battery

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.

Thanks. WE DO GO OFF-ROAD and sometimes it's very corrugated. Johno

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
