choice of batteries

Look for the Batteries


.

No doubt Neville you'll find that battery a good option, Century are good kit. Other good units are Delco and Yuasa (which are part of Century too I think).

I have gone with a marine type sealed battery for the aux battery in the patrol and its been great. Went that way after lots of research (marine I mean) then looked around for one reasonably priced, not a cheapie but a goodie at a reasonable price. Found they are much of a muchness for like batteries in price and ended up buying local.Mine are N70ZZ, the 70 is just the size of the battery and the ZZ means something like how the pos and neg terminals are arranged on the battery.

Doug's site (above) is a GREAT RESOURCE for all manner of 4b stuff, I have it bookmarked and refer to it when I need to link to or know stuff. (Don't tell Doug he'll get all self important hahahaha)

Nev,
You and I are similar - same motor and alternator and I run two engels - a 40litre as a fridge, and an old 39l as a cooler, although I tried the fridge/freezer combo in the past.

My setup is simply two N70 Exide Extreme batteries under the bonnet - one to start it, and the other is the auxillary with a Rotronics isolator. I am always driving each day, so the batteries get recharged daily. In hot weather, the auxillary battery will be down to about 12.0 volts overnight - i.e. mostly run down by the following morning. In normal winter weather, theres no issue - about 12.3volts at worst.

I guess it depends on how you want to use them. If you want to stay put for a day or two, you'll need a second auxillary battery.

Your 100series had twin starting batteries. Experience is that you only need one N70 to start this vehicle, so many people isolate the second battery on the drivers side and leave an N70 on the passengers side to crank the vehicle. You can fit a third battery in an aftermarket tray further back on the passengers side.

The confusing bit is all the conflicting info you'll get on forums about what type of battery to get. I use the Exide Extremes because I've had bad experiences with the wet cell deep cycle batteries, and I don't believe the AGMs will go the distance in the hot conditions under the bonnet. I buy two new batteries every 3 years, and relegate the used ones into my kids vehicles, where they last for many more years. But thats what suits me - won't suit many others.

I would recommend the All-Rounder.

MRV70 and MRV70L

105 a/h 760cca and M/free.

Call 1300 BATTERY for your local stockist.

Same as Phil, Exide Extreme's for me.

Thanks for the reply,s,
Have checked that site Doug and as we have a local dealer I will talk to him next week. Has anyone used the Optima in a 100 series?. I
have both batteries in paralel and have a low voltage cutout switch in the line, this has worked well with my original 60lt. Engel but feel that I will require a little more reserve particularly as I will run one fridge as a freezer.
Cheers and thanks, Nev.

The Optima battery is definately an AGM not a gel and is was developed bad in the eighties for the US Army.

To the chap with the 8 year old Full River well done but when are you going to use them as a battery life is based on cycles and if you were cycling them they would be dead.

I did not state mythical or otherwise figures I stated experience whereas the use was full charge ,full discharge and in a 24 hour period that is hard cycling not paper facts.

The best AGMs supposedly available and they cycled around 300 times at 100% and died.

This is experience like your statement and you have done exceptionally well dollar for dollar.

If you use Exide Extremes as a "Deep Cycle" or "cycling" battery to run accessories... then their warranty is only six (6) MONTHS.

Exide state the Extreme is a Passenger Vehicle battery and NOT a storage battery on their website->
Exide PASSENGER VEHICLE batteries

You will notice Passenger vehicle, Storage and Deep Cycle batteries are all on separate pages to avoid any confusion, after all if you wanted a Cranking battery why would you be interested in looking at the tech specs for a Deep Cycle or AGM battery and vice versa!

If Exide remove the Extreme from the "passenger battery" list and label it as "Deep Cycle" or "Cycling" battery and are prepared give it a 12 month warranty, then it's worth considering, but with it's present tech specs it will never happen, it's designed, built and also sold by Exide as a Cranking battery for a PASSENGER VEHICLE nothing more, why do you think exide only give the Extreme only 6 months warranty when used as a "cycling" battery ??


Sure you use a Cranking battery to run a fridge - and you can use *some* Deep Cycle as Cranking batteries too.

However, a Deep Cycle or AGM battery will run a fridge much more efficiently than a Cranking battery will, that's not just my opinion, that's a absolute, undeniable fact of life.

( I'm not saying it can't be done - I'm saying there are better battery choices out there that WILL work far more efficiently and cost much LESS $$$ in the long term )
Mainey...

Neville,
have found this information on the Century website for the "Severe Service" battery

LINK:-> Century SEVERE SERVICE battery


LINK:-> Century battery gives their version of Cranking V's Deep Cycle battery

Neville,

I replaced my two standard Toyota batteries with the Champion N70ZZ and N70ZZL after one went at Karumba at 2.5 years. The L indicates the terminals are reversed which is required in the TD100 to fit the wiring loom between the two batteries.

Didn't have much choice in Mt Isa but they are manufactured by Exide in any case. I'm no auto elecrician but they seem to be doing the job OK.

I have a 100AH AGM in the rear running through a Pirahna isolator for the fridge etc.
