> Batteries tend to be at 80%+ capacity after 10+ years
do they use some kind of special battery tech? because that's not the common experience with battery operated devices, every phone I have ever owned had half battery life after one year. Same for laptops. Even the super efficient macbook air m1 I have now lasts half what it did two years ago.
I have never seen a battery last ten years, let alone do it at 80% capacity.
- jdlshore 3y agoBetter battery management, more careful charging patterns and leveling, better temperature management. You can do a lot more with a big pack of batteries in a car than the few cells in your phone or laptop.
- mjamesaustin 3y agoThere are a couple factors: • Car batteries are thermally managed much better than your laptop or especially your phone, which helps longevity • Much larger capacity means a similar amount of battery cycles lasts a long time. 1000 cycles is common for lithium ion, which in a 300 mile range car means 300,000 miles

- user_7832 3y agoI'm not an expert on batteries, but iphone batteries are specifically known to be poorly rated (iirc 500 cycles till 80%). iPads & macs are I think 1000 cycles. Car batteries are likely much higher. The interesting thing is by reducing the charging window (aka charging only between 30-70% for eg) you can greatly boost the cycles the battery will last.
