gsapatka Posted September 26, 2011 Report Share Posted September 26, 2011 I have a DW890 that I bought years ago. i came with the standard black charger (DW9116) with the "conditioning button". I have recently purchased a new dual charger (DC 9320). My questions are: 1. Is the old charger as "good" as the new one? 2 Can I leave the batteries in the chargers (old & new) without harming the batteries? Quote Link to comment Share on other sites More sharing options...
