While rummaging through my drawer, I found a handful of AA and AAA rechargeable batteries that I’d almost forgotten about. I decided to give this EBL 8-Bay charger a shot, and I was surprised to see how sleek and compact it is—way smaller than I imagined for an 8-bay charger.

The first thing that caught my eye was the smart LED indicators. They change from red to green as the batteries charge, which makes it super easy to monitor progress without guessing.

I popped in a mix of Ni-MH and Ni-Cd batteries, and the charger automatically detected their status—no need to manually set anything.

I left it running overnight, and all batteries came out fully energized without any issues.
