Re: [NTLK] Need battery info on socket communications pagecard

Hi Frank,

All I could find online was this safety data sheet which has no
specific info:
http://www.duracell.com/oem/safety/pdf/2019.4A.pdf

And this site which lists it but has no details:
http://batterier.batterier.se/produkter/open_produkter/
produktinfo_body.asp?prodid=14389

Duracell's own conversion database does not find an equivalent for
the PR1662.

I had a look at my own specialist battery suppliers and they do not
list it.

However, because I keep all my old paper references, I looked through
an old RS Components catalogue and it was there:

DA630H Dia. 15.6mm x H. 6.2mm
1.4V / 950mAh
Max constant current @ 1.1V: 30mA
Approximate operational life @ 0.9V: 350hrs @ 470Ω
Load range: 36Ω to 3kΩ

Self-discharge rates are said to be high if not connected to a load,
so old batteries are likely to be bad.

In July 1998 it was sold individually and cost 87 pence. There is a
very small colour picture of all the zinc-air batteries together and
the DA630 must be the largest of the coin cells (which is having its
tab pulled off).

None of the other zinc-air cells they list have the same dimensions
and I can find no other current coin battery of any kind that has
these dimensions.

There is a good chart of equivalents here:

replacement-guide/

It looks like you may have to compromise on the battery and suffer
poor performance or power the card externally perhaps from a lithium
cell and LDA regulator.

Joel.
