Is it true that Renault batteries fail faster in hot climates or is that just a rumor?
Hi everyone, I'm starting to wonder if I made a mistake buying a French car in Abu Dhabi or if I just have terrible luck with batteries. I have a 2019 Renault Megane that I bought second hand about eighteen months ago and this will be the second time I'm replacing the battery if I go through with it. The first time was about eight months ago when the car just wouldn't start one morning for no apparent reason. I called a mobile service, they put in a new battery, and everything was fine until last week. Now the car is starting to hesitate again, not every time but maybe once every few days. Sometimes it fires right up and other times it cranks slowly like the battery is weak. I took it to a mechanic who tested the charging system and said the alternator is working fine and there's no parasitic drain that he could find. He shrugged and said some cars just go through batteries faster than others especially in this heat. That answer didn't really satisfy me because I don't want to just keep buying new batteries every year without understanding why. I started doing some research online to see if other Renault owners have had similar issues. I found a page that had a lot of detailed information about Renault battery problems and common solutions. The website was something like https://www.carbatteryreplacement-abu-dhabi.ae/renault-battery-replacement and it mentioned that some Renault models have a known issue where the battery management system doesn't charge the battery properly during short trips. That actually makes a lot of sense because most of my driving is just a ten minute commute to work and back. The battery never gets a chance to fully recharge. The page also suggested that using a higher quality battery with better heat resistance might help extend the life. So now I'm wondering if I should just accept that I need to replace my battery every year given my driving habits and the climate here. Or is there something else I should be looking for like a battery maintainer or trickle charger that can keep the battery healthy even when I'm only doing short trips? Has anyone else with a Renault experienced this same pattern of batteries dying fast? And if you found a solution please share it because I'm really tired of this cycle. Thanks everyone.
