Battery tender overcharging?

So I just got a new Deltran battery tender and hooked it up to my 848 via the quick connect. It went to green flashing light pretty fast and couple hours later the green light was still flashing. I thought this couldn't be right considering I fully charged a motorcycle battery with this same tender and it didn't even take that long. I put on another Deltran tender I have laying around thinking maybe its a faulty unit and this one did the same thing with the green flashing light. I hooked up aligator clips via the quick connect on the bike and checked the voltage and it showed 14 volts, so it seems the tender is overcharing the battery but for whatever reason it doesn't want to go into "maintain mode" with the solid green light. I was reading around and read someone say that a tender should charge a battery up to around 14.7 volts before it goes into maintain mode? What do you guys think, should I just leave the damn thing on for a day and see if it ever goes into maintain mode?

How long should it stay in the green flashing light mode? Wouldn't 2 hours be too long?

The flashing green means the battery is about 80% capacity. The tender is charging at 750mah so it will take a while to get to capacity. Make sure you don't have a drain on the battery or left the parking light on with the ignition. You should be ok leaving it connected.

Buy a BatteryMINDER by VDC Electronics and be done with it. My Deltran Battery Tendor never fully charged my YUASA......I found (only around %80 +/- charged when checked by a pro instrument). The BatteryMINDER charged the battery completely then maintains it.

I think you're fine. At a slow charge rate of 750mah it could take several days to peak to full charge. Slow charging at low amperage is a good thing for a battery. A comparison would be having a full size empty swimming pool and trying to fill it by peeing in it. That's going to take a while. They make the peak charge rate slow because it's better for the battery. It takes time though.

But it was around 14 volts when I disconnected the tender and checked the voltage. Wouldn't it be around 12 volts fully charged?
