I was really worried about my battery dying while I was away for a month, but I did a bit of research and found a simple solution that worked perfectly. I asked a friend to come over once a week and start my car and let it run for about 15 minutes, which I was told is enough to keep the battery charged and the alternator working. I also disconnected the negative terminal just to be safe, which I know some people don't recommend for newer cars because of the electronics, but for my 2018 model it was fine and I didn't have any issues when I reconnected it. When I got back from my trip, the car started straight away with no problems at all. I was so relieved because I'd heard so many stories about people coming back to dead batteries, especially in the summer when the heat just makes everything worse. I've also heard that there are battery maintainers you can buy that plug into the cigarette lighter and keep the battery topped up, which sounds like an even easier solution. I found a great option for one of those through a local supplier I discovered at batteryzoneuae.com/ and I'm planning to get one for future trips. If you're going to be away for a while, I'd definitely recommend taking some precautions because a dead battery is the last thing you want to deal with after a long flight when you're tired and just want to get home. Even just having someone start the car once a week can make all the difference. I'll probably invest in a maintainer for next time because it seems like the simplest solution.
