TL;DR Most EV batteries will last longer than the cars they’re in. Battery degradation is at better (meaning: lower) rates than expected. Slow charging is better. Drive EV and don’t worry about your battery.
„Our 2025 analysis of over 22,700 electric vehicles, covering 21 different vehicle models, confirms that overall, modern EV batteries are robust and built to last beyond a typical vehicle’s service life.“
“On Saturday 31st January 2026, GWR (Great Western Railway) introduced the UK’s first battery-only powered train into passenger service.”

Impressive re-use of materials and adoption of current technologies to create a new class of vehicle. Testing and validation bodes well for future deployment elsewhere.

Just received our first prototype of a Nickel-metal Hydride battery charger with a USB plug. This board is made to charge from 1 to 6 cells in series and supports a thermister for sensing overheating batteries.
This circuit design is planned to be a part of a pen-like stylus with a camera and haptic feedback for blind people to feel visual art.

This afternoon, I took advantage of the rain to tidy up and clean my desk, as well as part of the cabinet to my right, which houses the switch and the Raspberry Pi 4 (powered by FreeBSD) that I use for various services.
I came across my old laptop again: a 2019 16" MacBook Pro, the last Intel model. I think it was one of the worst devices I’ve ever owned: sluggish, fans always loud, and the case 'polished' down quickly just from my hands. I used it for about a year, then passed it to my wife when I got the M1 Pro MBP - which I’m still using - in early 2022. By comparison, the Apple Silicon model feels brand new, even after four years of fairly intense use.
My wife had to stop using the 'old' one because the battery, despite having very few charge cycles, is practically dead. It doesn’t hold a charge, but that wouldn’t even be the biggest issue. The real trouble is that without a functional battery, it has become incredibly slow, with the fans constantly blasting, making it unusable. I tried turning it on again, but it even struggles to launch the macOS installer. I’m stuck: replacing the battery would cost 289 euros (from what I’ve read, the entire top case needs to be replaced), but I hate to leave it like this, as the hardware and screen still have a lot to offer.
I’ve thought about selling it as-is, but I think it would be difficult - an inexperienced buyer wouldn't understand that the slowness is caused specifically by the battery issue.
Any advice?
