Thu, 16 Oct 2025 How good is the battery in a used electric vehicle?

Companies are offering tech they say can accurately test the health of batteries in used EVs.

* Battery health has become a crucial factor in buying second-hand electric vehicles, with concerns over how previous owners have charged and maintained the batteries.
* A company called Aviloo offers battery health certificates for used EVs, which can provide detailed information on the condition of individual cells within the battery.
* Aviloo's chief executive says that an EV's state of health (SOH) below 80% doesn't necessarily mean it's too far gone and can still be a great car if priced accordingly.
* Industry experts say that some EVs are lasting longer than predicted, with improved battery technology allowing for more charging cycles before degradation.
* Battery analytics firms can provide detailed information on the condition of used EV batteries, helping to alleviate concerns for potential buyers.
* Some car manufacturers use built-in analytics systems to generate SOH reports, but these may not always be accurate or comparable.
* Experts recommend finding a balance between frequent fast charging and avoiding it altogether to best take care of an EV's battery.
