Yeah, kind of strange not having some random person add a comment that doesn't make sence from any but his/her perspective.
But it is really refreshing, I can name a couple that I dont like on the fordf150.net

I have another maintainer I use on my trailer batteries called the BatteryMinder Plus, and it says it only goes into the "maintenance/desulphation" mode when the charging voltage reaches 14 V. (It has to get this high during charging, indicating a lot of "back emf" or "charging resistance" to be at a full charge state).
Now, CCA can be a bit misleading. It refers to cranking ability. It's the number of amps a battery can support for 30 seconds at a temperature of 0 degrees F until the battery voltage drops to unusable levels. It's not the same thing as "cranking amps", which is what you get at 32 degrees F and it's not the same as "reserve capacity", which is more a measure of total power stored.

I worked at Tractor Supply Co. for over a year (in high school so I was actually an old timer towards the end. lol) and can pretty much run everything except receiving although I can do some of that. We usually considered a battery fully charged at 12 to 12.6 so it makes sence that I'd be a little off.
