I have a lacross it is fine. I like it for testing the batteries and if I don't need charged batteries in 20min, for that I have a 8 cell charger Powerex MH-C801D Charger
Been using 2 of the Powerex MH-C9000s for several years now with some Panasonic Eneloop Pros. Imo the best battery and charger combination for scanners that use AA.
