I have recently power surged a couple of 18v drill batteries to bring them back to life.
I would now like to discharge them.
I've thought of connecting an 18V bulb which can be bought ,but ive no idea what the wattages are and what the rate/time of the discharge should be.
Any advice would be apreciated, and no im not holding the trigger down on the drill for an hour or so.

How did you do that?

F-clamp or stout rubber band around trigger, or clamp in a workmate
You probably won't need to.

Probably not a good idea to discharge them because they are multi-cell and you would damage the weakest cells by reverse charging them at the end of the discharge.
Quite. Presumably the idea is to test their capacity. Any load will discharge them, no need to buy one. Stick a 100w mains filament bulb on them.
If you've just fried shorting whiskers, they won't last long - let us know how long.

IMHO ... drill some holes, drill be be flat soon enough
I have a couple of dead drill batteries that I would like to bring back to life so I can recharge them. Can you explain how to "power surge"? Thanks PeteK
so I can recharge them. Can you explain how to "power surge"?
Don't bother. It's a very short term 'fix' even if it works.
What you would expect from a top poster.

Do let us know how you get on.
