A battery charging device

A battery charging device (1) has charging terminals (4) in a seat (5) for a battery (B). The seat (5) is in a seat module which may be replaced by a module for a different battery type. Also, the seat module has a hinged extension piece (71) which allows it to be used with different batteries, depending on the position of the extension piece. The terminals (4) are protected by a cover (10) which pivots between a covering position protecting the terminals and a supporting position after rotation to a rearward stable position.
