Hi,

Anyone leave the standard Smart fortwo charger plugged into the car when the battery is at 100%? Understand the recommendation is to keep the batter between 20% and 80% but want to get the most out a drive. More important do not want to damage the car or battey. Specifcally mind is a 2014 Smart fortwo ED. Thanks in advance for the feedback.

Relax,,,,No problem ! The car's BCM (battery control module) is doing all of the thinking for you. It knows all of the charging advice that you hear from the battery Experts and a lot of tricks that are too sophisticated for you and I to worry about.
It will only accept an 80% charge, but it tells you that you got 100% and likewise it will protect you from total discharge (when you car is telling you otherwise).
When your car, The BCM, has fully charged, reading 100%, it shuts off the connection to your power source. So Relax, leave it plugged-in, but don't expect to get some Extra charge above the cars indicated 100%.
