[time-nuts] Austron 1210D-03 Battery Pack Ideas

[Mike Feher]

Brooke -

Thanks for the suggestion. I did want to replace them with the same
chemistry for the reasons you stated. You are of course also correct that
the more modern cells have a higher A/Hr capacity. So, sounds like regular
modern NiCd D cells will be the way to go. That was my inclination to begin
with, but, since John was probably also facing a similar problem I thought I
would ask. Thanks for the ideas and the URL. I will check them out. 73 -

Hi Mike:

http://www.batteryspace.com has a number of Ni-Cad and Ni-MH cells.  
It's a good idea to replace with the same chemistry so that the charger 
works properly.  Most modern batteries have a capacity that's much 
higher than batteries 10 or 20 years ago, so getting the exact same size 
is not so important.  Better to make up a smaller battery but that has 
about the same number of cells and Amp-Hour capacity.  Note that many 
cells are available with pre welded tabs to simplify making up a battery 
pack.  They also have a number of pre assembled battery packs, one of 
which may be just what  you need.

I see that John already has posted that the battery was 12 "F" cells 
each speced as 1.2 Volts and 7 AH.  This is less than a modern "D" cell.

Battery Space also carries "Universal" chargers that are the "Burp" type 
which are in my opinion the only way to go.
http://www.batteryspace.com/index.asp?PageAction=VIEWCATS&Category=944   
<- some 12 and 14.4 Volt packs.
But if a 2x6 configuration is not correct then combine some smaller 
packs like:

If you make an online order use the discount code:    batteryspace    
for a little off.

Have Fun,
