Batteries

[DarkMatter]

A 12 V Nicad and a 12V Lead Acid can be charged in parallel?

Yes, if the charging voltage is correct, and the current is correctly
limited to the NiCad.

The reason a NiCad and a lead acid cannot be charged together would
be charging rate.

A lead acid battery can handle surges, and fast charge rates. The
NiCad has to be charged slowly to keep internal heating to a minimum
acceptable value.

This means things would have to be constantly monitored, and fully
charged units be removed at the appropriate times

No battery charging system can just be all balls constant voltage
sources.

So, yeah, Mr. Extreme case retard, they CAN be if monitored, and
current limited properly.

The scenario being discussed, however IS different.

YOU obviously didn't grasp much at all of the original post, boy.

You are mistaken. The OP specifically said 2 lead acid 12v batteries.

He is also incorrect about charging. I know you know these
things... they are for the brit twit that doesn't know shit...

Both are charged "by voltage". To charge a battery, one MUST exceed
the operating voltage of the battery. One just happens to be current
limited, which is, in essence applying a voltage over that of the
battery such that a specific current is maintained.

With a 12V lead acid, anything over around 12.5 or so volts will
allow a charge gain, BUT up to around 14 is used, and the currents
vary in that realm based on the Ri of the battery. It is merely a
wider window for a more resilient battery.

Small batteries heat more when charged, and charge rate must be
maintained and monitored more. They are STILL charged by a voltage
that exceeds their voltage of operation. That makes them "voltage
charged" devices as well. They just require a better, or smart even
charging system. An EMF over the battery voltage is STILL the engine
at work here.

Whoopie fuckin' doo. The post *I* responded to had you telling him
what *you* would do. I simply stated that it was NOT required.

You were doing fine, until you Jumped on the Keith 'Tard bandwagon
... again.

You repeatedly stated it was "not required".....and, I never argued that
point nor did I ever say it "was required"....so why are you still stating
that the diode is "not required"????
There is no point to make here and that is why my only response to you was
"read the post"......

 

[Ross Mac]

Then you spewed.


I didn't say that you said they were. READ IT, DIPSHIT.

I merely said they are NOIT required.

Don't get yer bloomers in a bunch, and get your head out of Keith's
ass.

Here is a quote directly from your post above....

No diode is needed

You have repeated that several times....point made!!!...
If you prefer the manual method...go for it!
It really doen't matter to me what gets your batteries charged!!!

It is your post and your bumptious manner to
which I replied below, and not the OP.

You've been caught out.

Silly Boy.

That you have made a fool of yourself by jumping in
with scornful comments that were applicable to yourself
is not erased by your ongoing silly comments.
