Meet SecondWind, a state-of-the-art, EnergyStar-approved design that will bring life back to your dead batteries. The SecondWind accommodates any combination of normal, store-bought AA and AAA alkaline batteries, charging up to four at a time. It takes 90 minutes to reach a full charge, and this smart little device even detects defective batteries—so you’ll know when it’s time to really let go.
Charger designed for use with disposable alkaline batteries. When charging alkaline batteries will not leak, generate heat or be a safety hazard. Do not place extremely old, physically damaged or leaking batteries into the SecondWind battery charger. When possible, use brand name batteries since their higher manufacturing quality will lead to a longer battery lifespan. The SecondWInd battery charger is not compatible with NiMH, NiCAD or Lithium-based batteries.
