If say I replace my current (pun apologies) lead acid Exide battery on my M3W with a LiPoFe Antigravity battery, could I still use a NOCO booster/starter in the event of say lights being left on in error and the battery isolator switch not being disconnected? I would not then need to arrange for a battery tender for the Morgan, when it is left in storage over the winter in France, when I am back in the UK. This year was the first year in eight, when I have not arrived at the storage to find someone has unplugged my battery tender to use the socket for something else and has forgotten to plug it back in. This year I will have a different storage arrangement, as the previous location, where I had free storage, has been sold off. I have negotiated with a local classic and historic car restoration company, in the next door village to me, Villecroze and they want to have my M3W on display in their office in return for free storage. I would prefer not to have to rely on them for a power supply for my CTEK battery tender. I am using an H-D rectifier charge controller (Electra Glide) after 4 yes 4 CE rectifier/controller failures. I assume this will work well with the Antigravity battery.

I have a battery isolator switch on my vehicles for safety reasons, other than my Panamera Hybrid, where the 20 odd computers will throw a total wobbly if the battery is disconnected. You even have to connect a 12V source to the OBD2 port when replacing the 12V AGM service battery, otherwise the vehicle will have to be trailered to a Porsche dealer to be re-initialised. Even if the 12V battery drops fractionally below 12V due to being left for a couple of weeks together with very cold weather, the car will refuse to initialise, which is why I have a NOCO booster. It only needs to be connected for a few seconds until the car initialises and the DC to DC converter kicks in to raise the service voltage above 12V, from the lithium ion traction battery. There is no starter motor as such on the petrol engine of the Panamera and it is fired by the 140 BHP/250 lbs/ft electric traction motor, which sits between the petrol engine and 8 speed PDK gearbox.
