I had a bit of a scare with my hybrid last week when it wouldn't start after being parked at the airport. I assumed it was the main hybrid battery, but after some research I learned it was actually the small 12V auxiliary battery that had died. Apparently, this is a super common issue here because the heat wreaks havoc on them, and most of us don't even think about it. I found a guide that explains everything, from why AGM batteries are better for our climate to how short trips in EV mode can actually drain that auxiliary battery without you realizing. It's packed with useful info for anyone with a hybrid or EV in the UAE. Visit this page if you want to avoid the same mistake I made.
