I have a CMM 1000 type 4, 19 inch mulch mower by black & decker. Not able to get a full charge on battery, they been replaced 2 month ago, & yes it did charge & turn green light on. Not anymore, is there a switch or something that control the charge?
Answers & Comments
Try running the battery right down to fully flat this should reset the diods to fully recharge the battery again
