Your battery sounds healthy as does the charging system. 11.9 is nominal for a decent battery since the electronics wants good voltage. Much lower and the fuel pump and injection isn't happy. Bump starting with low voltage is difficult.
My Garmin has a voltage gauge and reads about 3 tenths low but I have a relative value to observe. Keeps the worries away.

 

Thanks for the info.
What Garmin do you use that shows voltage information also?

 

Not sure where the 11.9 volts is coming from, I assume it must be key on/engine off? 12.4 volts on the battery is low. 12.6 - 12.8 is better. Only check this after the battery has been off a charger for a couple hours at least.

Charging at 14.4-14.6 definitely sounds higher than normal to me. That indicates a charging system that might be trying to make up for a weak cell in a battery. I would have that battery load tested with a proper device.

Nah that is about right, my 1000 with a brand spanking new battery reads about 14.6 as it also did with the old battery.

 

The Garmin I have is an old, ancient,craved from stone GPS III plus.
Full of little choices like voltage, sun set, and the like.
Amazing at what information it provides in maps for being so old. I yanked the batteries and hard wired it. It's also how I keep track of my rear tire life too.
They are on Ebay for cheap. I paid hundreds for mine many eons ago.
