Thanks for all the help

Another HC question. There are times I don't run my layout for months. The HC batteries go dead, then it takes 12 - 14 hours to charge them up. I was thinking of plugging the battery charger into a timer and have the timer turn the battery charger on once a day for an hour to keep the batteries charged. Good idea or not? I was also thinking of having two timers. Timer #1 would run timer #2 for an hour every day. Timer #2 would be set to run the charger an hour every 12 days. Good, bad, better than the first idea?
Thanks
