I am guessing you meant 13.2V in the OP. 14.4V is too high for a long term storage type deal. Most battery tenders(over winter type) are in the 13.2-13.7 range. My understanding is 14.4V is slowly boiling off the acid in the battery.Yes, typo, I meant to say 13.2. I also used to believe that 14 volts would boil away the water but according to the Concours voltage display, its charging voltage is 14.2 +/- 2 and that seems to be the spec for most all automotive charging systems. Then, there is maintenance free batteries that don't have water to boil away. BTW, I have this charger on my VFR and I think the batt is lead/acid type.

The green light comes on and the red light goes out indicating trickle or maintenance mode but the charging voltage is still 14.4. I left hooked up for 24 hours and still 14.4 I have an onboard voltmeter on the VFR connected directly to the battery. I think the charger is defective. I am going to contact customer service.
I will use nothing but the Battery Tender brand, there is a good reason why they are the best.

The Battery Tender Jr. uses the charge, monitor, recharge method. I have 2 of them in use, and would recommend them for your C14.
Just stay away from prolonged use of a "trickle" charger. Most chargers meant for prolonged use are labeled as "maintainers".
Interestingly, the Battery Tender Jr. is labeled in some places as a maintainer and others as a trickle charger. In their own documentation it says:
"Step 4) Float Charge: Red Light Off, Green Light On. Constant Voltage at Float / Maintenance level. Keeps battery fully charged and maintains high specific gravity. Full charge reset monitor protects battery against excessive appliance current draw while charging. Float charge continues indefinitely."
Which means it really *is* a trickle charger (after it has brought the battery up to full charge). They don't seem to be worried about applying constant float charge as opposed to turning it off and monitoring, then applying intermittent full charges to keep it charged.
Really, you hang around to see the little green light?Often. You're supposed to wait for green to go, right?
