Hi Mark.
You asked:
why do so many battery operated equipments
state that they must not be operated using rechargeable batteries?
There is no one all-purpose reason, but the two main ones, at least the ones
I worry about with battery powered stuff, are:
1. As you already implied,
Mark,
The key here, I think, is that batteries vary wildly. Not all reasons for
the ban are the same, either.
Many years ago, when NiCd's were first appearing on the market, some
electronic photoflash units carried the same ban. It SEEMS to have been
due to limited inrush-current capability

Hello all
I've a question regarding the fire enclosure and the EN60065:1998.
Clause 2.8.11 defines the potential fire source. I understand that such a
source is defined by two criterion :
1 - The open voltage must be 50V
and 2 - The apparent power in default condition must be
Mark,
I am no battery expert, but I believe that in an article that
I read some time ago, Ni-Cads have a lower internal resistance
than alkaline or zinc chloride cells. If this is true, then
loads incorporating motors could possibly take excessive
currents at start-up.

Hi Mark
One possibility is that Ni Cads can develop a memory if you
don't fully discharge them and then recharge them they will only discharge
to the level they were previously discharged to. Most Camcorder
manufacturers provide you with a load to discharge the batteries before you
Dear Al,
For large in-house photocopy-and- compiling machines used for fully
automatic production of publications, books I would think the Machinery
Directive applies.
Does anyone know what the applicable UL Standards for such equipment? I
would assume standards relating to Graphic Arts
