Flat battery at the airport.

[DARYL DEVEREUX]

Guys , have owned my truck for almost 2 years, love my truck, but approx 5 months in I have a flat battery at th airport after being away for 4 days, then it happened again and the dealer replaced the battery and stated I should always lock it up inside my private garage. It happened again a month ago when we need for a life threatening emergency, flat battery, ambulance arrived 1.5 hours later. Truck was carried to dealer who had it for approximately 3 weeks( medically wasn’t allowed to drive) They have done software updates , left it for days seeing if something draws down on the battery, all good. Get my truck back, locking it in my garage, and photographing my electrical status on start up and close down for the day, two days ago I had a 20% drop over night from 94% to 72%, so far nothing else. I don’t trust what is going on with this “parasite discharge. Grenadier UK asked for photos of my garage, apparently someone in Oz had some electrical equipment which affected the battery status ( beats me). Wanted to fit the wolf mirror, dealer would not fit(don’t want to lose my warranty) so in sits in my cupboard.
This is a known about problem, but what is the answer, because I don’t trust my beautiful truck anymore and I am waiting for it to let me down AGAIN.
I want it fixed so I can continue to enjoy it
Regards Proud Grenadier owner, but now with trust issues

It looks like the emergeny was on you? I hope you're well. The most important thing.

May I ask why the ambulance took 1,5 hours? For emergencies this is always too late..

Moved thread. Not an active emergency.

Fwiw. My 24p if left for anything like 4 days looses about 20% battery charge. Since I bought it 6 months ago it never has had more than a 92% battery.

I took a reading after a long trip and then another after 4 days stationary- 12.52v down to 12.25v- both are below optimal reading I’m told. Dealership was not interested. Told me that they need trickle charged or run regularly- which at the time I did think- what about when I leave the country / go to an airport.

I also left it this winter for 5 days the battery said -4c temp / 0% charge! It had been very cold and was left outside with about 16” of snow encasing it. It started first time and I ran it for 4 hours which increase the battery % charge. The only noticeable thing was the stop start cancellation warning sounded immediately on start up.

My local dealership has the showroom ones on constant trickle charge overnight .

This has happened to me twice in 5 months of ownership. The first time I caught the battery at 50% charge after 2 days without driving. Went for a drive and all ok.

The second time, a couple of months later - absolutely flat after 3 days without driving, resulting in a airbag error. Going to the dealer next week to get it reset.

There's no pattern to this - it's just a random power drain of around an amp or two, I think. Very difficult to track down, but clearly a fault.

I've added a second spare 90Ahr battery (not connected) and some jump leads in the second battery space, just in case I get stuck. I'm working on adding a DC-DC trickle charger to keep the extra battery topped up.

I've taken to checking the state of charge of the battery every day even if I don't drive just to make sure everything is ok.

It's clearly unreasonable to anyone to say that you have to drive a Genadier or keep it on trickle charge for a 4 day layover. 4 weeks - possibly, but 4 days no. It's a fault

Totally agree with your last 2 sentences. Ineos need to sort this.

Hopefully the op will have better luck than I , especially given it was unreliable at a time when it really needed it to be.

These are not 90s imported lada’s as after all….(although the lada was renowned for being able to start in significant sub zero temperatures, I think in some cases rumoured by lighting a small fire under them to defrost- won’t be doing that to my grenadier thanks).

I’ve recently learned the battery needs to be calibrated by Ineos software to charge more accurately.

BMS should be reset to say it’s got a new battery. This can only be done via Ineos software. I had this done on my recent service and has made some improvements to the charging SOC and the amps.

However, it doesn’t stop the battery drain but because the battery is measuring and charging more accurately, fingers crossed won’t leave you stranded.

Double locking on the key fob and keeping the doors closed are recommended.

Good advice.
I always double lock on the fob, mainly (as a mildly autistic gent) who can’t wait for the lights to go out and isn’t trusting, so I press again to ensure it’s locked and doors all closed.

My wagon has not seen much use before me and the rear doors and narrow boot are especially stiff and easy to half close if not slammed home; resulting in the car not locking at all!

the double press ensures I am confident all doors are closed; which in turn means I don’t awake a 2am to go outside to check.
