Surprising rechargeable cell life
Clearing out the shed I came across my old 4.8v Challenge Extreme
powered screwdriver, which I hadn't seen for at least 6 years (I use my Hitachi drill/driver instead). When I opened the box and took out the screwdriver I accidently touched the trigger and was amazed when the motor turned. I though it might be the dregs of a charge in the cells, but I tried again and it turned. In fact, it was not possible to stop it turning by gripping the shaft. I have no idea what brand NiMH cells were used in this cheap screwdriver (Argos), but for the four of them to retain a good charge for 6 years seems very unusual to me. -- Jeff |
