Battery %

[MarkH]

I'd like to know this ~ I'll take some photos and maybe someone will recognise the unit?

It should be near the starter somewhere if there is one.

Or leave it permanently plugged into something like a CTEK whilst parked.

Better to give it a charge then disconnect. Chargers can produce AC ripple which isn't ideal for lead acid batteries. A small solar panel is better for long term connection. DC loves DC.

BTW, battery monitoring manufacturers show customers 100% charged even if not. I had a chat with a Balmar guy (Balmar should be well known in the US), as we sell Balmar Battery monitors. He said, when the load display stucks at 9tysomewhat %, people tend to ask what is wrong an call the service hotline. To prevent that, they show 100% (full charged), even if not 100% charged, but the people are not afraid that something could be wrong. If a battery monitor doesn't do that trick, you might always end up with 9tysomething %...but no need to start worrying. Normal driving with a normal generator almost never fully charges any battery. Normal driving with advanced charging technology can do it.

Thanks chaps, i drive around 60 miles a day to and from work so that should be enough for battery maintenance.
After i posted i remembered my last car had rear air suspension that was always active. If on holiday longer than 2 weeks i would come back to a car that wouldn't start,
To get round this i fitted an auxiliary socket (cigarette lighter) with a direct feed to the battery and would put a solar charging panel in the front screen when away, after i never came back to a car that wouldn't start, but obviously had to park with direct sunlight.

Surprised it only got to 91% after several long trips. Mines seen 96% from an 85% start on a single long journey. Although, I wonder if it could just be a calibration thing?

Your peak amp charging figures are also much lower than mine, but not sure if there's any inference to draw from that. You could try leaving the Offroad electrical screen on and let it stop/start a few times to see what the screen says. When I've done this I've seen a screen reading of 340 or 380 amps (now I can't quite remember) momentarily, before dropping down to double digit figures.

Do you have a CTEK charger? It may help to plug one in and leave for a few days to top both batteries up.

Will be ordering a CTEK charger and the cable to charge via the 10/13 pin trailer socket.

One would think that the starter battery would drain super slow. many of the things that run in background of newer cars don't exist on the IG. I feel like there is a vampire draw going on when battery is down to 70% after 2 days of non driving. Do you see a difference if the aux battery is switched off. Would a isolator swiych make a difference

 

[AWo]

Have you measured the current when the car is off for an hour?

IG owners could compare the values. So you get a base line of what can be considered as normal.

Battery appears to lose 10% of charge per week with no driving.
It is unclear how accurate the Ineos battery monitoring system is.
I’m off tomorrow for a 2 week road trip across France, so the battery will get charged.

I'd say it's only the starter battery being monitored as it needs to apply to vehicles without the aux battery. To get a percentage readout there must be some basic shunt on the starter somewhere to measure amps in & out but I doubt it'd be accurate.
Parasitic loads will drain the starter overtime. Wise to throw a charger on the under bonnet terminals every month or so if no long drives.

So this is the main starter battery (I also have the auxiliary fitted):

Attached to the positive terminal is this:

And attached to the negative terminal is this:

Anyone recognise them?

I googled the part number ... something like Renault Espace V 2.0 DCI adblue clems, but don't ask me what it is, am in a restaurant now, eating, alone in a remote location

So this looks very much like this:

The negative terminal attachment might be a current sensing device which provides "feedback" to the variable output alternator to ensure it's providing sufficient output to meet all the demands..

 

[DCPU]

Yes, I think you're on the right track there.

I haven't found the exact match yet in the Tyco product range (I'm still looking), but it looks suspiciously similar to this generic item:

" A battery sensor is used to precisely monitor/measure the current, voltage, and temperature of rechargeable batteries. It provides real time status information such as state of charge (SOC), state of health (aging), and state of function (SOF) parameters of batteries.

Battery sensor is a mechatronic device that features sensor modules with necessary electronics & integrated battery detection algorithm. The mechanical parts include shunt resistors for measuring current, battery clamp for installing with the battery terminal, threaded bolt for attaching the ground cable, and a plug connector for interfacing with energy management systems.

State of Charge (SOC) represents how much charge is available in the battery. SOC (%) of a battery cell refers to the ratio of the remaining charge of a battery to its rated capacity. If SOC is 50%, then the battery is in a half-charged state.

State of health (SOH) indicates the ability of the battery to receive and deliver energy as compared to its ideal conditions. SoH value of battery will be 100% at the time of manufacture and will decrease over time and use.

State of function (SoF) reflects battery readiness in terms of usable energy by observing state-of-charge in relation to the available capacity.

Battery sensor maximizes the battery life by avoiding deep discharge and supports fuel saving and CO2 emission reduction technologies such as smart alternator control, and start/stop or recuperation. It is ideal for use in light commercial vehicles, hybrid vehicles, UPS, electric forklifts, golf carts, emergency lighting, medical beds, and solar panel monitoring."

And although I don't know this applies to the system fitted to the Grenadier, I think it's useful information to be aware of:

Please don't flame me . I have been driving for 40+years and never worried about the charge level of a battery, the vehicle would either start or not. If the alternator light can on then i would worry.
Most of the vehicles i drove had mechanical diesel pumps so would start wit a push.
This is my first new car in 15 years, so is the battery charge level really that important ??

Apart from voltage sensitive electronics, the Grenadier will not start with a push.

 

[DCPU]

That's if you could push it...

 

[Eric]

Apart from voltage sensitive electronics, the Grenadier will not start with a push.

The days of push starting a modern vehicle are long gone.

I’ll be keeping a battery jump starter with me for overlanding as recommended by an Ineos technician
i have a Noco boost GB 70
