So to me thats doing it job.
Did some reading where it wasnt good to have it at 14.4 for too long
As long as you’re happy ........... however it is incorrect to say that it is doing it’s job, it’s not. It’s only doing part of it’s job. What you have read is correct.

It should drop into float mode once it gets up to 14.4v & has held it there for a set time, & that doesn’t sound like it’s happening. If you were to forget to disconnect your battery it would kill it by overcharging, or worse it could kill you. Unlikely, but possible. If it’s a wet battery it could boil it dry. If it’s an AGM you could end up with thermal runaway.

Thermal Runaway

Thermal runaway is a condition in which the battery temperature increases rapidly resulting in extreme overheating of the battery. Under rare conditions, the battery can melt, catch on fire, or even explode. Thermal runaway can only occur if the battery is at high ambient temperature and/or the charging voltage is set too high. As the battery accepts current, its internal temperature rises. The rise in temperature reduces the battery impedance, causing it to accept more current. The higher current further heats the battery, and so on, causing the battery temperature to “runaway”. An upper limit will eventually be reached when the electrolyte starts to boil, but once the electrolyte has boiled away, the temperature can climb even further to the point of plastic meltdown and possible fire.
