Anyway to keep battery "topped" off?

Tesla: "To maintain service life, the battery pack should be stored at a state of charge (SOC) of 15 to 50%."

Currently I charge my CT to 50% for daily driving and have a schedule set to charge from 12am to 6am, so if I dont drive much during the day and charge from 46% to 50% the charging usually ends early around 4am.. So from 4am to 6am I may lose a percent or two, maybe more if sentry is on..

So if the charger is plugged in should it not keep it charged at 50%, or maybe it perhaps kicks on after a certain amount has dropped? Just not sure how it works..
Get rid of the start time and set schedule to end at 6am.

I’m in the same boat where I do not put daily commuting miles on my CT, and therefore I keep the battery state of charge around 50%. In order to do so, in the warm months I charge it up to 55% and then cycle down to 45%. My local utility has 1/2-off electric rates from midnight to 8 AM, so I Level One trickle charge (120 V) at night over that eight hour period to give me 5% back onto the battery by morning. Ideally, this will approximately average 50% S. O. C., extending battery life. I’m also fortunate enough to have a supercharger a few minutes down the road so that if I ever need more range, I have it available at the drop of a hat.

For the winter months, since I’ve observed a significant range drop during cold weather, I boosted my max charge limit to 67%. This gives me about 61% on the meter, but I am estimating the range is about the same as 55%.
