Aux. battery for minimal use.

[loanrangie]

I need a new aux battery but since it will see minimal use whats the best type to use in this situation , another cranking batt or a dual purpose batt ?

Should add that i have a pirahna dual batt setup if it makes a difference and nothing currently setup to draw current from an aux battery.

I bought a couple of Supercharge All rounders (650m CCA /105AH each) (AULRO discount :p) which I used for the CY trip last year. They have separate sets of terminals...for starting and deep cycle. They haven't had a real work out for about 12 months. Since new they've had Innox treatment and I keep them wired in parallel and on a floating 6 stage smart charger. They are kept in a work room in the house when not needed for trips... No point dragging around an extra 52 kg unnecessarily :eek:

I have a SC gold main battery thats been great so i was thinking about an all rounder for my aux, so if used in a dual batt setup would you hook up the cranking terminals to the solenoid and use the deep cycle for power draw ? It would stay in the vehicle .

I have a 75amp/h deep cycle battery you can have. It about the size of an N70. It's used as it's out of our Rectifier/UPS's at work but test ok. We change them as a routine but still good. I run them in mine. I have one in the camper and just charge it before I go away. I run everything all weekend and hardly drops in voltage. Let me know if your interested and I'll through one in the car for you.

Dave that would be awesome mate, i should have posted earlier as i'm away camping this weekend but i 'll arrange to catch up soon.

regards,
Nick.

No worries Nick, I'll throw one in the car tomorrow as I'm stuck working all weekend. PM me when you get back and we can arrange something. Have a good weekend away, I hope it's not to wet. Which way are you heading?

Out Warburton way, it will be wet but we are prepared and the kids will love it anyway.

Yep, that seems a good approach!

[loanrangie]

Collected the deep cycle battery from Dave today and will drop it into the aux. batt tray later on, will i do any damage to it if i leave it connected to my dual batt system or should i only charge it when required ?

You can leave it hooked up to your dual battery system to keep it topped up. Deep Cycle batteries charge better if you have a smart electronic type isolator for dissimilar batteries rather than the basic solenoid type, but I would try it and see how it goes. You could always top it up before a trip away to be sure. It's basically still a 12V battery but the charge voltages and current are a little bit different for optimum performance.
