And that an AGM used in a cycling application will struggle to recharge with a variable voltage that often drops to 12v before it's replenished. It's not an issue for the starter as it's not cycling...cranking draws very little ah.
    Wet cell batteries benefit from much higher voltages than AGMs can tolerate.

    Land Rover voltages can drop to 13.2v but they regularly peak at 14.7v.

    So with these types of voltages, any type af lead acid battery will charge perfectly using nothing more than the Land Rover’s alternator. And note, the batteries will charge much faster as well.

    Furthermore, using my isolators will mean the cranking battery can be cycled down to 12.0v and with more than 4,500 D3s, D4s and RRS out there, fitted with my isolators, if there was a problem, it would have shown up by now.

    Instead of causing problems, my isolators have been proven to not only do a far better job of charging auxiliary and house batteries, but they also improve the lifespan of the cranking battery.

    No other system comes close to what my isolators achieve and that goes for any form of DC/DC setup.

    Second Battery

    I have a 2017 L494.
    Main battery is under the spare wheel but interested to find out if the second stop start battery is no longer behind the right rear panel (from comments above) does anyone know where it now resides?
    Regards

    I'm not sure it was ever behind the panel, it is a fairly small battery and doesn't need a lot of space. The diagram I saw is inconclusive but does show it on it's side on the RHS near the main battery.

    Probably the easiest way to determine the location is to remove the panels and the spare wheel and look around.

    Mine is a MY 15.5 and I took the panel off to look, the Aux battery is in there . Also took the LHS panel off, and there is plenty of room in there, I may look at a way of modifying the panel to make an access door.

    Thanks for checking. Can you see where the negative cable from the auxiliary battery goes?

    Hi Geedublya, it goes straight to the body, you can see the bolt in the photo... the cable goes behind the red cable with black spiral tape. (the primary battery apparently has a BMS on its negative terminal)

    What does Topix say about your aux battery? When I look in Topix for my VIN it has AUXILLARY BATTERY 14AH B19 . I am thinking your aux battery should be 70AH or thereabouts.... not sure where they could hide that .

    Hi Greg, from what I understand reading the parts lists there are two auxiliary batteries available. A 14AH for normal stop start and a 70AH for cold climates. They both go into the same spot with different clamping systems. I suspect that cold climates use a lot more power with seat heaters, windscreen heaters, steering wheel heaters and so on and require the larger battery.
    Fortunately mine has no stop start facility so I have an empty shelf and can use it for an optima D34 or some other suitably sized battery.


    Is it the bolt I have circled in the picture? Sorry it isn't very clear to me looking at the picture

    Yes, that's it.

    The MY14 that I had access to was fitted with the larger battery so perhaps initially LR considered that Australia was cold-climate but now not.

    It may depend on if you select the cold climate pack when ordering.
