You have to worry about float and trickle charge because otherwise your battery will never fully charge and will deteriorate. The battery will stand 13.8 volts 24/7. If the current has tapered off fully and you remove the charger then the battery is not fully charged.

This is the battery I am trying to charge but I do not want to pull it out of the box it is in every time I need to charge it.

I'm going to read the "Little Red Book" and return with more knowledgeable questions. Thanks for the help.

If your use of this battery is "cyclic" meaning you use it a bit, charge it and then leave it for some time until needed again, then you really need a dedicated charger that will charge to nearer 15 volts and then taper the voltage down. This type of charger monitors the current and reduces the voltage down toward a "float" charge level as the battery charges. The higher voltage ensures the battery charges in a relatively short time. If your charging it in a car then you haven't the higher voltage available, all you have is the cars alternator voltage will can be anywhere from under 13 volts on a red hot day with a red hot engine to nearer 16 volts (for a few seconds) on an icy cold start. A shottky diode in series with the battery charging lead is probably all you need tbh and just keep it connected to the car lighter socket.

If you'd like a digital voltmeter, you can get little LED modules on eBay for a couple of bucks (search for LED voltmeter). Wire it up with a switch so it doesn't drain the battery unnecessarily.
I bought 2 of those, handle little things for 1 buck.
