Okay, we love our EVs, but those batteries can be kinda picky. To keep them running strong for years, we need to follow some basic rules – nothing crazy, but it's worth knowing.

Jason over at Engineering Explained (fellow nerd, we love him) lays it out perfectly:

EV Battery Life

Rule #1: Don't baby your battery TOO much.

Leaving your EV charged to 100% all the time, especially in the heat, is a bad idea. Lithium-ion batteries lose power over time anyway, but that gets worse if they're always full, especially in hot weather. So, if you're gonna be gone for a while, drain it down to 30% or so.

Rule #2: Don't let it go bone-dry either.

We know it's tempting to use up every single mile of range, but batteries actually prefer being topped up regularly. Think of those full-depth charges (0% to 100%) like junk food for your car. Try to keep it above 25% whenever possible.

Rule #3: No need to max it out all the time.

For everyday driving, it's actually better to keep the charge under 80%. That last little bit at the top stresses the battery. Road trips are the exception, of course, but for your daily commute, stick to a more relaxed charging routine.

EV Battery Life

Basically, treat your EV battery like you SHOULD treat yourself – moderation, avoid extreme highs and lows, and remember that consistency is key! Do this, and that battery should be humming along for years.

Your Front Brakes Do Most of the Work, So Why Did the Rear Pads Wear Out First?

The usual explanation sounds perfectly logical. When a car slows down, its weight moves toward the front. The front tires carry more load, so the front brakes provide more of the stopping force. That
