Batteries degrade over time, but charging to only 80 percent instead of 100 percent significantly slows battery degradation in devices like MacBooks.
Just like in a fully electric vehicle, the battery in a plug-in hybrid (PHEV) loses its capacity to hold a charge over time. A new study shows which PHEV batteries stay healthy the longestand which degrade more quickly. This matters a whole lot, because EV batteries are expensive. If a PHEV's pack is defective, it may be uneconomical to repair and could potentially even render the vehicle a write-off.
