What's the effect on battery life of regularly charging to 100%

Why not do what I do . Charge to 90% , gives you another 25 miles of range and still leaves a healthy buffer below 100% . You are using the car after the charge so not leaving it at a high state of charge so everything will be fine.

It also gives somewhere for any recouped power to go from the brakes.

TBH , regen still works at 100% but at a lower level . It doesn't take long for it to go back to normal as the regen is no where near the power you are using when driving.

My wife has a 145 mile round journey for her three days a week commute in an MG Trophy LR (61kw battery). We have been charging to 80% in line with recommendations to preserve battery life. But now that winter is coming she is experiencing range anxiety. I say don't worry but that is easy for me to say as I am not experiencing what she is. Today, for example, she was limiting her speed to around 50mph on roads that are 70mph to ensure she had a decent margin of charge to get her home. When she got home she had 12% left (i.e. she was achieving 3.5 miles per kw and had a decent margin to spare) which would be fine if she wasn't having to limit her speed. Limiting her speed in this way is not at all ideal as it prolongs an already long working day so I think she may have to revert to 100% battery charging. Does anyone have any information or evidence on the impact on battery life of 100% charging?

p.s. she is driving in energy saving mode, max regen etc.

This is one of the reasons I bought the SE, you can charge it to 100% all the time and it’s lighter improving handling

It's only 16 kgs lighter, so will have minimal impact on handling

This is resurrection of an old thread!

Just charge your car to whatever level you need to use and don't worry about it.

The SR is quicker than the LR but that is mainly gearing, not weight.
