What is the best charging and discharge plan to have the optimum whole life battery performance.

[Dave53]

I don't mean to argue Kithmo, but surely degradation in battery performance will affect charging times, rates of acceleration, the regeneration efficiency and range of your car? A degraded battery will affect your driving experience in a number of ways and hence in the resale value of your car too. And if MG only step in if the battery falls below 70% capacity that's a lot of degradation down to a range of c100 miles max.
I have no idea how well the BMS looks after the battery, but, if we can adopt simply least damage plan that would surely be beneficial?

To be honest, I'm more worried about the breakdown of the technology in the car once the car reaches 7 years when the Guarantee expires far more than issues with the battery, anything that goes wrong with the electronics will be a very pricy hit in the wallet, the time has gone when you can get out your socket set and spanners, MG have and will continue to protect the battery for the seven years if it feels its necessary,they are computing data from the cars at services and will adjust the BMS if required, which has already happened.

Some stuff isn't covered for the whole 7 years, including driver aids, only covered for 3 years.

What are you thinking is going to be pricey? Most of the parts prices I've seen have been really cheap compared to most other makes. Also there's the fact that there are so few things to go wrong, maintenance costs should be really low.
