    Thanks Tim, It is surely a thing of beauty!! Ran the car for a few minutes and then shut it down and connected the Charger to the Anderson Plug. Cranking Battery went to 14.9v and has stayed there for about an hour now, getting a good charge. Thanks for your help with this. I sort of thought it should charge this was as it has in the past when using a Solar panel. The car was run this morning so not sure why it didn't charge straight through before?? I have tried it a few times over the last few days with no good results either. anyway, appreciate your help,

    The Traxide will not connect your batteries unless your starting battery is well charged - I forget the exact level but it is about 80% I think.

    Sounds like your batteries may need a fair bit of maintenance charging.

    It is unusual for the USI-160 to shut down in such a short time, unless the batteries are in a low state of charge.

    Keep putting the solar on as often as possible, over the next week, and then see how long the USI-160 stays on.

    Thanks Tim, yes thew car has been doing a fair bit of short run work and not getting nay good Highway time, also my battery charger has been out of action. The charger is now up and going so will get some quality charging back into the Cranking Battery again over the coming week or so. Thanks again for you help, talk more soon.

    Keeps us informed on how your battery responds to some charging.

    Just thought i would give a follow up message on my Batteries.
    I have been using the Aux Battery to charge my Electric Golf Buggy Battery, through an inverter to the 24v charger. I put the Buggy on charge when i finish golf, then have drinks and a sandwich at the club, the drive home is about 30 minutes. I then remove the charger and turn it back on when going to golf again. This gets the golf buggy fully charged but with the other short runs i have been doing the car and aux batteries havent been getting up to full charge. The Corona situation has also meant my drive to golf is about 20 minutes instead of 30-40!!!

    I now have the Car Batteries on charge, they charged for about 16 hours overnight on Sunday and then 6 hours each on Monday and Tuesday. I rest them overnight and the Tuesday morning cranking battery level was 12.64v showing 94%, the Wednesday morning battery level 12.68v showing 99%. I will try to keep charging for 6 hours or so each day during this week and see how they go next week. I am aiming to also reduce the short runs in the car as it doesn't seem do it any good.

    lr4 Low battery, please start engine

    I have a Discovery 4 HSE 2012. In 2013 I put my car in Sydney garage to get a second car key from England. They had to re-program for both keys then issue appeared. The security unit required to be updated because it could not sync to the new key to recognize it. They replaced new unit then every thing was working perfect. A month after that time, message "Low battery please start engine" starting often until now 2021. Even I replace many batteries reset BMS but it still displays message if radio is on for 5 minutes or doors is not close properly. Check alternator it works well when charge = 14.4 volt and battery after stop charging = 12.6 volt. If no message displaying, battery is fine not dropping voltage. If there is a message, then battery voltage drops quick to 12.2 v. I believe that the security unit is still on and consume energy much. It supposes to sleep when lock until a trigger from door access to wake up.
    The question is what trigger the message to display? Why if there is no message so I can start its engine after one and half month never using it even in cold whether.
    Likely the message is not only in LR4 but on the entire Land Rover cars have the same problem with the design.
    Thinking of buying a new Defender but I hate to see this problem again. LR doesn't want to fix it at all not like Toyota or Nissan...They laugh at buyers and saying "THEY ARE IDIOTS".

    Nissan and Toyota have lots of “don’t want to fix it” episodes - far worse and more frequent than LR.

    Your low battery issues will be after multiple short drives. Nature of any vehicle.

    A SIMPLE BUT ACCURATE LOAD TEST

    How to do a LOAD TEST on your cranking battery at home.

    Have a look at the link below but before ( and after ) you do the Battery Maintenance Procedure, carry out this simple but accurate Load Test.


    This LOAD TEST is carried out for two reasons.

    First off, the Load Test will tell you if your cranking battery is still good.

    Second, if you carry out a load test at the beginning and at the end of a full week of Maintenance cycles, your will also see if the Maintenance charging has worked.


    To carry our a Load Test, if you have a dual battery setup, first disconnect the Negative ( - ) battery lead on your AUXILIARY battery.

    NOTE, if you have one of my new isolators ( supplied from the 01/01/22 ), you can simply switch the isolator to the LOCKED mode and the two batteries will be automatically disconnected and removes the need to disconnect the negative lead on the auxiliary battery.

    Next, with a digital multi meter, note the voltage of the cranking battery.

    Now turn your ignition on but DO NOT START YOUR MOTOR.

    With the ignition ON, turn your headlights on.

    Again, note the voltage at your cranking battery.

    Note the voltage every minute for the next 5 minutes.

    Regardless of what the voltage is, as long as it only drops for about the first two or three minutes and then levels out, your battery is good.

    If the voltage continually drops over the 5 minute period, then your battery is probably on its way out.

    After the 5 minute test, turn every thing off and reconnect the Auxiliary battery’s Negative leads or unlock the isolator.

    Now over the next week, follow and carry out the Maintenance procedure described in the link bellow.

    After the week of Maintenance cycles, carry out another Load Test and compere the voltages from the first teat to the last test.

    See if the voltages are now higher than those when you did the first Load Test.
