Hi again Spudboy and Skuilnaam is on the money, but your battery will still have heaps of power left in it..

The voltage levels you have posted up are for OPEN CIRCUIT voltage readings and are used to measure batteries that have been in a No-Charge/No-Load state for at least 24 hours.

If you want to keep an eye on your battery while you are away, that device is totally useless.

Here is a chart that you can use while small loads connected to your battery, like your compressor fridge, using an ordinary digital multi meter.

On the physical fitting side of things.
This is what I came across fitting an Optima Yellow top battery and the standard LR battery together with a Piranha Dual battery tray.

Had to remove the Aft wheel brace retaining clip and use the hole for a retaining bolt on the new tray.

Had to trim one side of the original battery ‘foot’ to fit the tray.

Still had to modify the tray due to the battery width. I intend to modify the tray again when the original gives up the ghost and I replace it with another Optima battery down the track.

Height difference between the two batteries created an issue with the ‘hold down clamp’.

Tried using the space provided with the Optima battery, but that just transferred the problem from one battery to the other!

Drives side of battery tray/passenger side of battery tray installed. (R/H side – L/H side)
Had to install and ‘crimp over’ the battery hold down clamping bolts prior to installing the tray otherwise I could not get them in with batteries in place. I did try…

All in. Modified and install a piece of plastic packing to make up the difference in height between the two batteries. Also used two flat ‘tie-down-straps’, one on each battery to make doubly sure things were secure. (Didn’t take any photos of straps installed)
I didn’t expect to run into these dramas during installation, but there you go I guess. :Thump:

My fitted mine without an issue, other than the height between the two batteries. With this I found the clamp just bent its self down as it tightened up.

I mounted mine further towards the rear of the seat box to allow the new "Award Winning" Red Arc 1225 BCDC dual battery In Car Charger (That is not a waste of money) to mount at the front of the box.

Cheers

Just remember that the nature of a person is to always justify their purchase or idea / ideal.

In much the same way you cannot convince a driver of an overpriced, over rated Toyota Land Cruiser that a more affordable Land Rover is better value and performance....

And there are far cheaper ways to get a set up that gives far better results with heaps of advantages over what any of these DC/DC devices can ever hope to do.

Just can't see the value of them.

Regarding the Optima, I have an Orbital (basically the same battery) as my second battery in the Puma. I put a square of rubber over the whole thing to stop the earth pole shorting out on the battery compartment.

Hi dmdigital, thats another good battery with similar characteristics to the Optima, including the fast charging capability.

What size ( ampere hours ) is it and how much was it?

Can't recall what I paid for it but it is rated as 750CCA and 50Ah. I know this is low but it will suffice my needs and also has clamp on and screw down connectors as well as being vibration proof.
