Mine too Chris.Mine certainly don't 'rust away'.....they are dry and cosseted...and only go out on dry days.
Where is this info from? If it is advisable to keep the battery between 20-80% why is an equalisation charge (which only happens after the battery is 100% charged) required to maximise battery life?I would say more than 3-4 days although, as with most things, there is no black and white answer. The possible additional degradation is debatable and likely to be affected by many other factors too. Equally, I wouldn't get overly worried if you can't for any reason but best minimise degradation by getting into good habits where there is little or no downside. Generally recommended to keep charge between 20 and 80% unless you need maximum range for specific trips. Hence choose a vehicle with sufficient range at 80% to cover most of your regular trips.
If this is true why does the battery need an equalisation charge (which only happens after a full slow charge) required regularly to maximise battery life?I had problems several times, after only a week of not being used "HV Battery Disconnected" which is caused by the 12v battery being too low. I complained to my dealer and eventually to MG. The first week of lockdown the car failed again, I charged the battery all morning but it still would not start. I was so fed up I called the AA.
After arranging a home visit, I received a call back from the AA Technical Dept and the guy gave me a cure :-
Lock and unlock the car with the KEY FOB.
Push the brake pedal as normal but at the same time apply half throttle
Now press the start button and it will be fine
This has worked everytime

That's so that the various cells with their various slightly different capacities can work best as a team. Equalisation is the solution to a different problem than battery life.If this is true why does the battery need an equalisation charge (which only happens after a full slow charge) required regularly to maximise battery life?
