I have a B&D cmm1200 that is not charging. My unit is 10 years old and i just assumed that the batteries were old and needing to be replaced. i purchased the new ones and installed them into the unit. it seemed to work great for the first couple of time that I mowed the lawn; however the last couple of time it will run out of power before i get done with 1/2 of the front yard. I plugged it into the charge and the charge light immediately goes from red to green. I have left it plugged in all week and now the same problem. Any direction at this point would be a great help.

Get a new charger. I am suprised your charger has lasted this long.
Be VERY careful when replacing rechargeable batteries with the ones that came with the unit. Rechargeable batteries come in NiCd (Nickel cadmium), NiMh (Nickel metal hydride), LiPo (Lithium Polymer) and lead acid. Using the wrong charger with the wrong batteries can lead to a fire. Replacing the charger with the wrong type will have the same end result.
