18v battery issues

[wadeyboy]

Hi , I have a 18v dc925 drill, one battery seemed to have given up 8 mths ago, so i shelved it and just used the other remaining battery which has now seemed to give up too, before buying a new drill i checked out a few battery revival videos on utube , all of which seemed to be with batteries reading 0 volts , so i checked mine and they read 13 volts and 16 volts but no power to the drill, so i put them both on charge resulting in 19.6 volts , but still no prolonged power to the drill, i had expected to at least find the battery that was shelved to read 0volts after 8 months stored if it was no good

Q> is it likely to be a problem in the drill ,

    what should the batteries read after charge

 

any help much appreciated

Sounds like a drill issue if you are getting the proper voltage.  Check the inside of the drill where the battery connects to make sure the prongs are not damage or obstructed.  Sometimes batteries will hold the voltage but when you apply load they will die very fast.  Sounds like they are just old batteries.

After charging batteries , then running drill till it dies which is about 1 minute , test the battery and they still read 19volts+,,, dont understand???
