I own an electric car and want to preserve battery performance. Beyond general methods like avoiding high temperatures and keeping the battery at a certain level regularly, what strategies do you recommend to maximize battery lifespan? Which methods do you personally use?

Man, I felt like I was throwing money into a black hole when I first calculated my Model 3’s battery depreciation last year. I charged it to 100% once for a road trip, and right after, I noticed the regen braking was a bit weaker on highways—little things like that bother me. So I started doing the 80/20 trick, letting it drop to 20% before plugging in, even if it means planning charges around grocery runs instead of road trips. Winter was brutal too; the first time I drove in below-freezing temps, the range dropped 30% overnight. Now I pre-condition the cabin while it’s still plugged in and keep the charge between 40-70% on days I’m not using it.
Honestly, what really clicked for me was realizing the battery hates extremes as much as I do. I got a small 120V trickle charger for my garage shelf just to top it up lightly during weeks I leave it sitting. I also switched to Tesla’s app reminder system for monthly “exercise” charges—when it pulses the battery at low and high states to keep the cells balanced. It’s like I’m babysitting a high-maintenance pet, but at this point, the battery’s lasted 18 months with only a 2% capacity loss.
