Battery Tesla or OEM Mazda
It's a Tesla thing.
Tesla doesn't keep a buffer zone at the top end of the battery. 100% means 100% in a Tesla. Tesla advises to only use 100% when you need the extra range.
My tesla model y recommendation is 90%. I know lfp batteries are recommended to do 100% at least weekly. We do 90% but drive the car about 100 miles every work day so it doesn't even sit at 90% for very long, maybe 3-4 hours.
2014 Mazda 3, about 65k km.\n\n2nd battery only because I left the lights on one time a few years ago and needed a replacement. Nil problems otherwise.
2018 Mazda 6 is going fine.\n\nProbably due for a battery soon as preventative maintenance.
All Teslas lose about 10% of their range in their first year. And then it levels off considerably after that.
I recently had to sell my 2013 model s for scrap value because the battery was out of spec. Tesla wanted 25k to replace. It was right at 200,000 miles.
My 2014 CX-5 eats batteries and always has since i bought it brand new. I usually have to replace 1x a year\u2026 and I know it\u2019s coming about 45 days in advance because my bluetooth and USB chargers will suddenly stop working and that\u2019s how i know oh my battery will die soon!
I have the same problem with my Mazada 3. Changed the battery while still under warranty and still does it. I don't leave anything pluggeded in and it still dies overnight. I purchased a battery tender and have to hook it up every night or get a boost in the morning.
My first Tesla battery died after 1.5 years of gentle use and the replacement they gave me is currently at 84%. Just like my 2 year old iPhone. Batteries degrade much more than these studies suggest.
Even then the Mazda oem battery is trash. My battery only last me 15k miles, and I bought it new.
