Black & Decker KC9036 Cordless Screwdriver Charger Voltage/Polarity?

I have a Black & Decker Cordless screwdriver model KC9036 3.6V model
(the one with the swivel handle).

Someone has taken my charger and I can't work out from the manual what
specification I need to replace it - it is a small barrel connector
but I don't know what polarity or voltage is required - presumably
something like 6V?, but there is no polarity marking on the
screwdriver or in the manual specifications. Not even sure it is a DC
supply...

Can anyone help? I guess the charger probably says what voltage it
delivers on it...

TIA.

I managed to throw the charger for mine (same model) away by mistake,
thinking it went with a knackered old drill/driver that I was throwing out.
I looked up where to order B&D spares from (quick Google) and rang up and
quoted my credit card number. Ok, I could have cobbled something together
out of the electronic junk box I suppose, but I too was lacking the info you
are enquiring about, and in the end it was less hassle just to cough up for
the genuine article. Unfortunately, I cannot recall how much it cost - about
a tenner I think, including carriage.

Thanks for the tip - however, as it happens I have access to all
manner of transformers, so I just wanted to know the voltage rating.

Luckily B & Q were prepared to open a pack and let me have a look - I
popped in this afternoon and apparently its 5.2V a.c. - as stamped on
the transformer casing,

Ah, but is that on-load or off load? I've been caught out like that before.

The stated voltage from a transformer is usually given as its on load
condition - anything else would be pointless. Also, the charging voltage
for a Ni-Cad isn't that critical - it's the current which matters.

OK, I didn't explain. I have found that the voltage quoted in chargers and
what used to be called "battery eliminators" (PSUs) often bears little
relation to what actually comes out of them. However, you are quite right
that in the case of a NiCd charger it will probably be current limited in
some crude way and the exact voltage is a bit academic. It's PSUs that are
really iffy - the regulation is often absolutely appalling.

In article <c752u0$nvf$1$8302...@news.demon.co.uk>,

The voltage quoted on any charger will be nominal since most will vary
according to the load. Apart from perhaps a constant voltage charger
designed for SLA batteries. With a 'battery eliminator', the battery it's
designed to replace will have a varying voltage according to state, so
assuming the eliminator stays within that window it should work ok.

With a regulated PSU, it should regulate reasonably well within its stated
load - but could well show nonsense if you check it open circuit.

But in the OP's case, it's purely a transformer as its output is AC.

I am sure Dave will be much relieved to finally have the answer 11 years
after he asked!

What kind of drill attachment do you have? Most are usually just add on
three jaw chucks with a hex mount shaft on the back. So you stick it in
the hex drive on the screwdriver and then put your drill in the chuck.

(note you can also get drills with a hex shank these days which are
probably easier than a wobbly chuck attachment)

I need a NEW one or a used.
How can I get it ?

Pop back to 2004 when that question was asked and they might still be
available!

(there are plenty of better alternatives available now)

Does anyone sell a 3.6v nicd charger today? With a nasty tool yes, without it I doubt it. You can always modify your own wallwart to do it.

So much-a-do about a 3.6 v screw driver?!
How much torque it has, or, what useful thing it can drive ?
Teeny weeny 2 mm screw to a depth of 5 to 10 mm
Big deal ...!!

I put up PB with a 2.4v one, it was perfectly capable of it. A mains drill was way quicker, though a challenge to control the stopping point. Thankfully things have moved on.

Why do battery vacuum cleaners brag about their battery voltage? It's
irrelevant.

an attempt to convince buyers they're [more] powerful

No it's not. Even an 18v pack can't deliver 1.6kW, imagine a 2.4v vac with the same cells.

For the same reason cordless power tools do. I expect they got the
habit directly from that source. I suspect it is 80% marketing, 15%
what sort of cells and motors the industry is tooled up for and perhaps
5% design optimisation; for instance, practical switch, wiring and
motor currents.

It's also a bit because back when NiCd were standard many tools had
'C' sized cells so the power/capacity *was* directly related to the
voltage. So, for example, a 12v tool had 8 x C cells and an 18v one
had 12 x C cells.

The same applies now - most LiIon packs are made up from a common cell
size, so more volts means higher energy density, and hence longer run
time or higher performance.

unlikely. Typically to replace a 5v ac supply you'd need 7v dc.

center pin positive and outer negative. I used a multi-selection charger as the original one has failed.

Rather unlikely that the op is still waiting to know that after 17 years.
