Thanks for your reply!! I guess I'll stick with the light bulb draw =
experiment for now;closely monitored.All I have now is a small l.e.d. =
bulb;Ill get a bigger one tomorrow.Ken R.

Be careful leaving the battery on the lights after the lights have =
stopped burning.
Like Al said, this is an old RC trick, used to revive old racing =
packs.
If you leave them on the lights, you risk reversing the voltage of the =
cell, or one of the cells that make up the pack.
The memory are really cystals inside the cell that is keeping it from =
fully draining or charging.
Cystals are built up a number of ways, like not fully discharging, not =
fully charging, etc.
NiCad batteries are bad for it, and the MH batteries were supposed to =
be less sensitive, but they'll still do it too.
Once cell voltage reversal has occured, you can't change it, and that =
cell is shot.=20
We used to run 12V auto bulbs in series to produce a very high amp =
draw. Once the lights went out, you HAD to pull the pack. After a bit, =
items like a Battery Bug or a pack staablizer were introduced, and this =
replaced the light bulbs set-up, and with built in circuitry, it would =
cease the draning once the pack discharged, to prevent the cell =
reversal.
Then you would either slow charge it fully, or use a higher end peak =
charger, which monitors the cell voltage and shuts off charging when =
peak voltage begins to drop.
Do a search on Nickel Cadmiuim batteries or RC battery care, and =
you'll find some more info on the subject.
Depending on the care, NiCads have about 1000 charges in them before =
they crap out.
I ran electrics for 10 years, before finally switching over to =
nitro-methane. Since I got into the VWs though, the poor RCs have just =
sat and collected dust.

memory makes the battery produce a sort of internal resistance. =
put it in the camcorder and it seems dead (just like a faulty ground =
cable on our roccos). put it in the charger, and it think its done in =
minutes (again, due to this resistance, dropping voltage, ending up with =
the outward appearance of a fully charged battery (as far the the =
charger can tell, from the outside)).
you need to fully discharge the battery (light bulb) for abt 6 =
hours (even if the bulb is hardly lit), then fully charge it (slowly, =
not the quick charger, if its an 8 hr slow charger, leave it for 24 hrs =
so the cells equalize), then do the light bulb thing again (abt 3 hrs =
past where it gets dim), and charge it one last time (slow, again, 24 =
hrs). this will attempt to get rid of the memory in nicd batteries.
if the batteries are very old, it may just be their time to go, =
especially if they are nicd.
the old light bulb trick comes from the r/c car days, people =
would fully discharge their packs with the same light bulb type things =
after each run.

Someone told me awhile ago,that if your camcorder battery won't =
take a charge anymore(develops a memory--???); that you need to put some =
kind of light with wires across the contact/charging terminals of the =
batt.If the light is connected right,the light will light up,and when it =
goes out completely you are supposed to be able to charge it up =
again.Has anyone heard of this before??? My batt. is undergoing this =
right now.I'll find out tomorrow if this works.Ken R.
