The Robert Bosch 18V Fast Battery Charger has dual-mode charging which means it can fully charge a spent CORE18V® 4 Ah battery in 55 minutes. The 8-Amp charging current delivers significant power featuring a regulated dual-mode charge which results in the first 80% of the charging being done very fast, while the remaining 20% is in long-life mode. The cooling fan helps protect batteries from overheating while charging. 

It is a flexible charging solution that is compatible with Bosch 18V batteries and the AMPShare™ System. The BC1880 provides a charging status indicator. It works with the AMPShare™ System, a battery system designed to be multi-brand compatible across many cordless products to make managing your work day easier. The 18V batteries and chargers in the system are compatible with Bosch 18V power tools and a growing list of cordless products from AMPShare™ brands.
