How to stop battery from draining
Do you ever check whether the battery is actually fully charged in the first place, the modern smart charging system has a habit of only partially charging the battery then relying on energy regeneration to complete the job. If there is little regen the battery can remain partially charged for... -

Dead Battery? Or its just damn cold. 6 F
Quote The battery in an LR4 generally only lasts 3 years or so. Quote If you have stop/start and disconnect the system the battery it will probably last twice that length of time. Aftermarket growth in AGM and EFB batteries used in start-stop vehicles has failed to meet predictions because the... -

Intelligent stop/start able to be disabled 2015/2016?
Try this, it works on Merc`s and Porsche with no issues. -

Stop start battery failure cause?
Having done that, did the system fully charge both battery`s, if yes then can you live with that misleading fault message to ensure your battery`s continue to get fully charged. Without the sensor my Porsche does not indicate the current charging voltage, to ensure everything is working as it... -

Stop start battery failure cause?
RANGE ROVER L322 VOGUE BATTERY MAINTENANCE LEAD LR037872. Works on my 2014 Cayman and the C Class Coupe, no lights on dash and no warnings other than stop/start deactivated. Unfortunately there must be a fault on your car, this sensor disconnect works on many vehicles. Best of luck. Rob. -

Stop start battery failure cause?
Fugi4, Have you disconnected the battery sensor, if so does the aux now have a charging voltage of around 14 volts. Members on the Ford F150 forum had problems with the aux battery not getting charged, up until 2018 Ford would code out smart charging, this fixed the issue, they no longer do... -

ECO Light
The aux might control it, but the sensor on the starter battery lets the engine management unit know whether there is enough energy in the starter battery to start the car after it has been stopped. The whole system is flawed, you might save a marginal amount of fuel with stop/start but it also... -

Stop start battery failure cause?
To test whether aux is being charged uncover aux battery, start the car, connect the probes of a multimeter to battery terminals, ensure meter is set to DC, you should see a reading around 14 volts. If it is less than 12 volts it`s not being charged. -

2011, 66k miles, flat battery issues
That`s correct but the car once locked should go to sleep within about 10 minutes, the drain on the battery should then be minimal otherwise the car could not be left at an airport or similar for lengthy periods without the battery going flat. Regarding the ECU`s energy draw, this is in... -

Land Rover LR4 H7 to H8 Battery Upgrade DIY
Are you going to let a computer inform you when to change your battery, that`s foolish, didn`t happen pre stop/start. If your car has a BMS, before replacing the battery and spending your hard earned disconnect the sensor (BMS) attached to the neg clamp of the starter battery, fully charge the... -

How to Disable the ECO Feature
Try this, also gets rid of smart charging which tends to leave the battery partially charged for extended periods, win, win. The aux battery is only there for stop/start. -

5.0 v8 timing chains
Were the 300,000 mile cars pre stop/start technology and did they have duplex chains, my theory is that the thousands of extra starts from that system may be causing these earlier failures. Overcoming the moment of inertia at each startup is when most loading occurs on the timing chain, well... -

ECO Light
If the starter motor is now stronger consider how long it will last with stop/start disconnected. The starter motor is only a minor issue, think about the timing chain, most are now single row, the maximum loading on the chain is at startup (hot or cold) when the stationary engine has to... -

2011, 66k miles, flat battery issues
Irreverent, the alternator the manufacturer installs is quite capable of providing adequate energy to run all these additional electronics and more, the real problem here is smart charging which often leaves the battery in a partial state of charge for extended periods, this shortens the life of...
