I would expect a lengthier charge under less strenuous circumstances but im happy with this

A couple of months later and especially within the last two weeks of summer break and a niece visiting and ruining the laptop every day and the battery now runs only about ten minutes less on a full charge but that can always change based on performance requirements

As an aside either with the original battery or this one i have only had the battery a little over a week but it is performing so well i wanted to tell others of the high quality battery incase your battery is under performing

The batteries inside the case are generic 18650 batteries but they are pretty decent qualityi did a teardown of the case to see what was insidethe run time is decent for generic batteries
