Reviving NiCd batteries
daywane:
I will let you know.
I have 6 batteries. I know are bad.
I charged them last week. All went dead with in 10 to 45 min.
all take a 90 min charge
most would light up charged in 30 or less min.
I have ordered new ones (well 2 new ones)

I hooked up my car battery charger
set to start.
reads 10.4 volts
with the volt meter I found - and + on battery, this is a 7.5
volt meter showed 6.v
zapped the crap out of it.
meter reads 8.5 volts now.
charging in charger as am posting.
these are for a motorola Radius p1225 2 way radio's
daywane:
so far so good.
been charging for 45 min and still charging.
good going so far
daywane:
well....light turned green in under 1.hr
:dunno
let me do 1 more and I will take them to work and see if it lasts all day.
I used to get 10 hrs out of em.
I just did 1 more.
batery was a 4 volts. I hit it a bunch of times, went up to 8.5 v.
this one is on the chager now
I was thinking my battery charger is not stong enough,
so I grabed 3 AA and a AAA batteries. ... Much bigger spark
these are on a 4 hr. charger now.
keep you posted
RayB:
If you crack open those power tool battery packs, you'll find them full of regular AA or C size rechargables.

daywane:
my 7.5 volt 2 way radio battery packs are no better.
I think 10+ volts are not enough.
It did work on the AAA or AA battery's
I opened a 2 way radio pack. It has 6 battery's bigger than AA but smaller than a C battery
7.5 volts divided into 6 = 1.25
I will cut 2 packs apart. zap each one , charge each one on my large charger and check voltage
It can charge AAA, AA, C , D, and 9 volt . but it takes 4 hrs and I can only do 4 at a time
If all else fails I can put in regular size AA nickel cadmium and have plenty of room left over
