Low battery warning

**VK3GJM** · 18th July 2015, 10:22 PM

Hi All,

Although the measurements conducted was not exact and the timing might be slightly out, the following is a result of a sluggish start and the Traxide being disconnected over the cause of the day.

All measurements conducted with Traxide disconnected and any other ancillary removed with the Discovery 4 MY2012 current consumption at +v battery terminal.

Unlock process with light on 8.82 amps but door not opened. Used remote control to unlock. Moved to front of vehicle.

Approx. 37 seconds later doors lock down, reading at 3.6 amps, 10 seconds later 0.81 amps.

4 minutes after locking 0.15 amps, 30 seconds later after locking 0.01 amps

Unlocked with door open and lights on 9.08 amps using keyless entry system, turned lights off with door open 5.77 amps mfd and radio still on with LR symbol.

4.5 minutes later mfd and radio LR symbol off, 2.12 amps, door still open. Did not time shutdown process with drivers door still open, but exceeded 10 minutes.

Close door 10 minutes later from 2.12 amps with slow ramp down to 1.35 amps, 20 seconds later 0.80 amps, then 0.53 amps, 8 minutes later 0.53 amps. 1.5 minutes later, 0.41 amps. 2 minutes later 0.01 amps.

Take 2, Lock closed drivers door, 2.5 minutes in 0.15 amps, at 3 minutes 0.01 amps.

My Jan built MY2012 D4 might be due for a new battery for long term reliability as the terminal voltage is a bit sick for an AGM at 11.87V.

The result might actually be due to insufficient charge time as the trip of about 10km to work from an overnight stand in the garage unlocked, again the following day get to work, all day locked and the cycle starts all over again.

Will try an AGM trickle charger for a week to lift state of charge.

Always lock the vehicle even when packed in garage.

Sorry about photo, iPad always has them upside down.

Regards

Gerald

An update people.
My D4 had this upgrade done at its first service,back in august.
Since having it done I have noted that the Jaycar ciggy voltmeter shows the battery charging for longer periods.
Big test was friday,D4 parked in shed for 6 weeks,half expected to jump start it.Pleasantly found 12.8V on the jaycar voltmeter when I woke it up,no begging for a start up due to low voltage.

Is there any way to see if this has been done.

I can't leave my car for a week without getting the low battery warning. Mind you I have the anti rust thingy which uses power. I also have a traxide unit installed. I have left my car for a couple of weeks and had left it on a charger which was on a timer to run twice a week.

I had my car serviced recently and nothing was mentioned about it. I will follow up with them I reckon.

Many thanks,
Richard

Try looking on your online log book,havent checked mine but the TSB upgrade was listed on the reciept.I had to tell them it needed doing as mine fell in that vin range.

I don't have access to the online log book. I have asked numerous times.
I went into TOPIX and it states no outstanding actions required.

I was not told that when I asked, you think they would do it automatically

I may have a faulty memory but I recall having to get something from my service department once for either this (service record or Topix setup) or some other record. Sorry I can't be more specific but it was a while ago.

Martin

I think it's the OSH - (Online Service History) code. It's required for registration.
