Aggressive pulse charging is spectacularly good at curing memory effect
in
Ni-Cd cells -- my experiments with Ni-Mh were somewhat less impressive.

Motorola introduced a pulse charger for Honeywell Strobonar
electronic-flash packs back in the '60s. "Modern Photography" hailed it
as a miracle -- it could actually bring near-dead packs back to life,
and significantly increase the capacity of "wilted" packs.

Several years later, I asked Bert Keppler why the product had
disappeared. "Uh... the battery packs blew up too often."

I have a pulse conditioner for Ni-Cd published in the current July/August
summer circuits issue of Elektor.

Its somewhat less aggressive than my original converted AT PSU, but the
cells remain cool throughout the treatment.
I may have noticed that, I can't remember if the summer issue is on the
newsstand here yet. I know I looked at the current issue recently, and
soemthing made me wonder if I "knew" the writer. But I can't remember
what the project was, or if I saw a name I wondered about.

This isn't the first time a denizen of this hierarchy made it into
Elektor. Andre somebody who used to be a regular in sci.electronics.
basics had a simple project, I can't remember what.

Over the years I've had a couple of bicycle lights published.

Hopefully the July/August issue also includes; my take on what might be in
the house coded chip in a 2D LED flashlight and an E-cigarette battery
charger.
