As long as its got a nominal voltage of around 12.8V or better it should crank, and your alternator should recharge the battery. To get back to peak nominal voltage takes about 20-30 minutes of driving.

The problem isn’t hot weather it’s more cold weather. But the people who have problems typically live in colder weather and most likely have something that has a constant draw on the battery even when car is off like alarm system, remote start, parking dash cameras etc.. or they have a 5 minute commute and never fully recharge the battery. Otherwise for the most part yes you can forget about it and use like normal battery. Only time I hook up to charger is if it’s sat for 5+days. If I know I’m not going to drive for 4+ days before hand I just unplug terminal, can sit for a year if it has zero draw. If I don’t know like this winter on day 4 when I was planning on driving it snowed so on day 5 i hooked up to a charger. Otherwise I just forget about it. Off a full charge I started car 5 times in a row little to no idle and 5th start up still cranked harder then OEM battery on full charge.
