Replacing clock battery, just want to make sure I understand this right..

[Malakie]

Hi,

Am replacing batteries on A2000's.   If I understand right, if I use a basic lithium 2032 coin cell battery holder, I need to use a diode to insure it does not charge.  Correct?    BUT if I use the same coin cell holder but use a rechargeable 2032 lithium battery, do NOT add the diode?

I am also reading something about adding a resistor?!

Yes, a LIR2032 should work.

And with this, no need for the diode correct?  Just want to be sure.  Because what I have is the two pin coin holder for the 2032.  Without the diode, it 'should' charge the LIR2032 or ML2032 (I have both), correct?

There's also these things which slot in directly. Tiny little board with the diode integrated so you can use off-the-shelf CR2032s from the drugstore.

I have a couple two pin basic 2032 holders now and a couple diodes, I understand they do require the diode so they don't receive a charge right?   It is the LIR or ML2032 I intend on using so with these same battery holders, I just forgo the diode and nothing more is needed... just want to make sure being this is modding that came along after I was around.

Never done myself on A2000.

You might find this thread helps;-

Most people fit the diode on the battery holder, which means only one pin soldered direct to the board. (Which is why you see pictures of battery holders with one end raised up).

A more demanding approach is to mod the tracks on the motherboard,

Are you sure you don't want to fit a lithium rechargeable coin cell?

umm.. all my posts above said I was probably use the lithium rechargeable.


I was asking if the diode was only for the CR2032 lithium coin cell NON rechargeable..  I wanted to double check since none of this was around back when I was involved in Amiga.   I am assuming the diode only gets used with the non chargeable 2032 and with the rechargeable 2032 I do not need that or anything else.  Just a basic coin holder and it will be good to go.   Just verifying things because there are dozen different methods, ways and comments out there, all different in how to do this.  Including using resistors and other newer components, all without any real explanation on why to use them.


So, the basic question I posed above was:    Use diode with non rechargeable 2032's and DON'T use with rechargeable 2032's, correct?  And that's it, nothing else needed?
