I have just bought a C-HR design but now i have to be away for 3 months and i will be storing the car on my front drive. I would be grateful for any advice on storage so that when i come back i wont have a problem with either battery
12v battery will not go through 3 months. You should disconnect it. But insurance may complain if the car is not in a secure space with battery disconnected and alarm off. So a garage would be the best place to store it. Breaks will also suffer, disks will rust. Tires will suffer too.
Electric battery will not care.
I would ask Toyota for specific guidance for long term storage. They may have good insight.
Thanks for the advice but i live in London and a garage would be the price of a small house so its a no go. I do have a frontage to my house where i can store the car and I've been wondering if one of those trickle chargers, the ones supposedly designed to keep your battery topped up are any good. any thoughts?
Yep, you connect to the battery in the boot. I've got a Ctek with a quick connection lead, so leave that permanently connected and just poking by the boot liner. Then connect it up once a month as I am very low mileage.
