The "smart" chargers like the Battery Tender have three operating stages (bulk charge, absorption charge, float) and even if you just rode several hours and the battery is fully charged, the tender still goes through its programmed routine when you hook it up. So it initially charges at the full 1.25 amps (solid red light) until the battery voltage reaches 14.4 volts, then it monitors the the charging current (flashing green and red) until it drops to 0.1 amp. When the charging current reaches that level it goes into float mode (green) and the voltage drops to around 13 volts.
Depending on the current draw of the always on accessories, and any excessive resistance in the wiring or the battery, it may take longer for some to reach the float stage than others. And some might never get there, so the tender has a time limit as well. If it hasn't gone into float mode through monitoring of the charging current, it will do so anyway after about 6 to 8 hours.
When you check for high resistance connections at the battery, don't forget to also check the connection from the Battery Tender to the bike harness. I found it necessary on mine several years ago to clean and then "tighten" the female half of the connector terminals. I also started using dielectric grease in the connectors to ward off corrosion.
This is just my off the cuff memory of how this thing works. If you want the real scoop, you might want to contact Deltran since my memory is suspect at best.

btw, it isn't necessary or even adviseable to hook up the charger after every ride. I hook mine up only if the bike is going to sit for at least a couple weeks or more. If you find you need to hook yours up after every ride to make it easier to start the next day, you need to check out the condition of your charging system and battery and look for abnormal current draws with everything off.
