    What battery type? NiMH, lithium? ... ? (the type is probably indicated in small print somewhere on the trimmer body)

    What are you trying to do? Eliminate the battery and power the trimmer directly from the charger? Or just use the charger to charge the battery?

    What is the battery capacity (mAh) rating?

    The charger is almost certainly going to be unable to power the device.

    I'm sure it takes many times longer to charge the battery than it takes to run it flat.

    It's not just a matter of reducing the voltage.
    Do you know how much current the trimmer motor draws (the mAh rating of the battery, together with the number of hours trimming per battery charge you get, would give us a clue)?
    What is the mA rating of the charger?

    The web-site doesn't have the info. In post #8 I asked you for the battery capacity. What does the label on the battery say?

    A battery of that size will typically have a capacity of ~500mAh to 1000mAh. If we assume 500mAh then a safe standard charging current would be, say, 40-50mA. It is likely, therefore, that the charger is rated for that sort of current. Your trimmer motor, however, will almost certainly draw a lot more than 50mA, particularly at start-up. Accordingly it is unlikely that the charger will power the motor (as Steve said).
