Leaving car for 3 months unattended

[Trenners]

Hi
I left my Mégane eTech for 3 months unattended - January through March 2025 - locked in my garage and when I returned home the main battery had only lost 5% charge.

I had really worried about this (as no one could really be sure how much charge would just drain away during the winter months) but it turns out I had absolutely nothing to worry about.

I did notice that the Mégane had gone into a deep sleep so the doors didn't automatically unlock as I approached the car with the key fob and I suspect it's been designed in this was as constantly scanning for the fob would drain more battery.

Anyhow ... Brilliant news for anyone thinking about leaving their car unattended for an extended period of time.

Hi Trenners,

This is very good news indeed. What a well thought out car.
It pays to buy an EV from a manufacturer like Renault that has a lot of experience in these things I think.
