battery

Try a forum search at the top of the index page, it has been done to death here.

Try Chris at Battery World Wantirna- AGM and redarc isolator- (hope I don't get into trouble with the mention, and no, I'm not his cousin, just got lots of explanation about what he recommended, then a neat job and a fair price. Wish everything I have bought was as straightforward.

Type in battery into forum search , when the headache subsides after reading 345,789 thousand items/comments/replies and you still cant make up your mind ,sell the 4x4 and buy a pushbike. LOL.

Your profile says you have a dual battery system. If it's for you, what is wrong with yours??? If its for someone else, why not recommend what you are using?

For the record we used a GSL electronic solenoid/isolator. Cost $120 from Wagner at Ashfield (Sydney)

I have a redarc smart solenoid I bought on ebay for $83.(to replace a rotronics isolator that gave up)Very easy unit to install and seems quite robust and water/dirt proof,unlike former unit. -Steve

Peter, you have asked for the "best dual battery system or at least a good quality one" so I can only assume you need it to isolate two different batteries, as I don’t believe you would be using a Cranking battery to run your fridge, or using a Deep Cycle battery as a starting battery - would you??

So I suggest you look at all the relevant manufacturer’s web sites for both the cheaper 'mechanical solenoid' systems and also the 'electronic’ isolator type of dual battery systems.

Look for one that actually has a written guarantee that it will 'effectively' work with two different types of batteries and has a warranty that ensures you won't have any charging problems with the Aux battery....

Generally a manufacturer will be offering, in writing, all the information you will require to make a competent decision, if a manufacturer does not state in writing the product will work with different batteries why would you buy it if you have different batteries ??? when other isolator manufacturers will actually guarantee their product will work ‘effectively’ with two different types of batteries….

If you have two identical batteries then any type of budget priced mechanical solenoid will suffice.

If you read any 4x4 forum you will see most guys ask for the ‘cheapest’ product and not as you have done, the “best or good quality”
You have to pay for quality in all products, it’s hard to believe the cheapest products will also have the exact same performance of the more expensive products available.

Like most people many years ago I was sold one of the cheaper products, on it’s website it was not stated as being suitable to be used with two different batteries, and it did not work effectively with my dual battery system, so I replaced it when shown by an Auto Sparky the difference available with an electronic isolator system.

Look at the Piranha and the Rotronics websites, both give a written guarantee their products will work effectively with two different batteries, unlike some of the less expensive mechanical solenoid products.

Hi Peter,

Are you just fishing or looking at fitting a new system ?

Redarc and ABR systems are great. What is wrong with your current set up ?

Regards Derek.

Hi Peter

There is a minefield of the "best" products out there so I will only tell you what I have installed.

Redarc solenoid - 120AH Fullriver AGM battery - Euroconverter battery guard (prevents auxiliary battery from discharging too much) - Sinergex 3-stage battery charger to bring battery to fully charged state.

I installed it all myself and it works for me for running an 70 LTR EvaKool fridge and some occasional fluro lighting.

Cheers .......

Thanks to all

Peter a
