Thread: How long before your battery goes flat?

Hi Ron, when I had my L322, it did not get much use and the cranking battery never lasted as much as 2 week before the battery was too low to start the motor, and I had a dual battery setup.

The best way to get the longest time out of your battery, is to do a regular overnight charge with a battery charger. and this is regardless of whether you drive your L322 or not.

Only a battery charge will keep the battery in good condition and the better the condition, the longer it takes to discharge.

Mine discharges at a rate I'm not happy with, 12.45v down to 12.2v over ~20 hours and that is with new batteries in a dual battery setup.

Have thrown a portable jump pack in the boot to save the embarrassment of calling RACV to the airport to give you a jump when you come back from holiday. Again.

How does this discharge rate compare to your experience?

Yeah even with 2x 110ah mine drops down over a week. I keep it perm on a charger as its my second vehicle. Probably get a little solar panel soon and leave it connected.

Is it a Traxide dual battery set up?
If so you could put a switch in the Negative wire from the relay/Module so you can turn it off and this will isolate the batteries.
This will not only reduce the current from the relay,but also separate the batteries and help locate the problem.

Couple of questions arising?

I have the same problem (yes Traxide with 2 under-bonnet batteries)

1 - presumably basically the same electrical system as my MY16 D4?

2 - how difficult/warranted to put the switch in the cab to overcome having to lift the bonnet to activate each time?

A simple fix for the older isolators is to fit a relay in the engine bay, near the isolator.

Wire the coil of the isolator so that one coil contact goes to an ignition circuit, and the other goes to earth.

Then wire the Isolators thin earth through the main contacts of the relay, so that the earth is connected while the motor is running and is disconnected when the motor is off.

If you want too, you can wire a small switch across the main contacts of the relay so you can bypass the relay when on a trip.

Easy just run a twin cable to switch in cab,then back to earth wire on relay.Hardest part is probably getting it through the firewall,others may know an easy way.
Or do as Tim says above,but i like to keep things simple and i can turn it on and off when ever i want to.

Thanks Tim.

Sorry, I've high-jacked the thread, but hopefully of interest to others with similar problems.

1 - So I guess my about 2 year old SC80 + IN CAB is considered an older isolator?

2 - I was particularly interested in the possibility of an in cab over-ride switch because where I park its a pain to get to open and close the bonnet.
