I've been driving in Dubai for over ten years and I've lost count of how many batteries I've bought. I always assumed it was just the heat. Everyone says heat kills batteries so I never questioned it. But something didn't add up. My friend has the same car as me, parks outside just like me, and his batteries last almost twice as long. The only real difference between us is our commutes. He drives mostly on Al Khail Road with steady traffic flow. I drive through downtown areas with constant stopping and starting. I started researching this because I was tired of being the guy who always needs a jump start. I came across this page https://dubaimetromap.ae/dubai-traffic-congestion-battery-health and honestly I felt a bit silly for not understanding this sooner. The article explained that when you're driving at steady speeds, the alternator spins fast and produces plenty of power to charge the battery. But when you're stuck in stop and go traffic, the engine spends most of its time at idle where the alternator isn't spinning fast enough. Meanwhile the AC is still running, the radio is on, the phone is charging, and all the car's computers are awake. The battery ends up discharging during all those idle periods. Over weeks and months, the battery never gets a proper full charge and eventually it just gives up. That explains everything. My stop and go commute was slowly killing my battery while my friend's steady highway commute kept his battery happy. Now I'm trying to change my route even if it adds a few kilometers, just to keep the car moving at steady speeds. I've only been doing it for two months but so far so good. Just wanted to share this in case anyone else is in the same boat and hasn't figured out why their battery keeps dying despite buying good brands. Sometimes it's not the battery. It's the traffic.
