We used, what we think is the correct charger,

Batteries are only good for about a year, if they are older than that, take them back to the store and see if they are guaranteed at all, (all Ryobi tools and batteries have a date code on them, and they are all guaranteed for 2 years, a little plug for Ryobi,) that is all I buy now days, they work great. So, to check your charger, you will need a volt meter set on 12 or 20 v dc, and see if the charger is putting out, if not, then, the cost of a new ryobi might be the same as the fix for the black and decker. That is if you use the thing, we use our cordless tools every day and charge them every night, hope this helps.

Hi, no it wont the charger will not give it enough power on its own to allow you to use it, you need to leave it to charge as the charger only trickle charges it slowly to prevent damage being done to the battery, so you cant use it whilst its on charge as this could cause the charger to over heat.

you need to leave it on charge before you use it.

let me know if you need further assistance ok

plz rate this solution as i have a whole page on unrated posts, thanks

if you know how to use a volt ohm meter you can check your charger, battery and switch.

3amps

Depends on which charger you have. With a quick charger it takes around 3 hours. With the regular charger it takes over night.

9VAC-100mA
this is right off my charger. it also says 6V on it
this is too bad, I have a charger and no tool and you have the tool and no charger

The pivot has to be in the straight position and the charger plugs in the joint (it's hidden in the bent position)

this one dosn't charge. It takes batterys. how do i change them

The female plug is directly in the center of the underside of the handle...Inserted the AC Charger/
That was it.
