Switching to a new apartment with basement parking, should I be worried about my car battery?

I am moving to a new place in Jumeirah next month and one of the only things giving me a little pause about it is the parking situation. The building has a multi level underground garage and my spot is on the second basement level which means the car will basically be sitting in an enclosed concrete space almost twenty four hours a day except when I am driving to work and back. My current apartment has open air parking on the roof level and even though the sun is brutal up there my battery has lasted nearly three years without any real problems so I am a bit nervous about making this change. A colleague warned me that understanding why batteries fail in basements is actually something worth looking into before assuming underground is automatically better and that comment stuck with me enough to do some proper reading before the move. What I found was more detailed than I expected honestly. The main issue is not just heat or cold but a specific combination of factors that underground parking creates in a city like Dubai, things like trapped moisture that has nowhere to escape in an enclosed space, the way concrete slowly releases stored heat throughout the night creating temperature swings the battery has to deal with constantly, and reduced airflow that allows corrosion to build up on terminals faster than it would in an open environment. None of these things cause immediate dramatic failure but together over several months they quietly wear down a battery that might otherwise last years longer. I also read that cars parked in basements for long stretches without being driven are particularly vulnerable because there is no charging happening to offset the slow passive drain that every car experiences when sitting still. I am not going to let this stop me from taking the apartment because it is otherwise perfect but I am going in with a plan now, regular terminal checks, a trickle charger for long weekends, and a voltage test every three months or so. Feels much better to know what to watch for ahead of time.
