Hi all,
I have a Gold Card which has the discontinued 40LF220 lithium battery. The
equivalent MGL0025 is also discontinued, and even with the long shelf life
of these lithium batteries, the new old stock ones are now useless. When
you
can find them, they were manufactured in 2002 and cost $30+ - one place
quoted me $140 for a minimum order of 5, plus shipping.
Is there a ready-made adaptor PCB available that will allow me to use a
CR2032?
Does the Super Gold Card use the same battery?
If not, I would be happy to design and manufacture a limited run of these
adaptors to use CR2032s so we can all have our battery backed clocks
working
again. I cannot make a guess on price as I have not looked at the cost of
short-run PCBs recently.
I would be happy to send batches of these to traders in each country at
cost
price.
What is the need/demand for something like this?
I am sure that would be popular. I keep getting asked about these
batteries. All my GC/SGC batteries are dead, but (of course) my systems use
the Minerva clock.
Is the CR2032 man enough though?
The CR2032 is 3V 235ma, and on this card would need to be replaced every
three years or so, which would be a simple "pop a new one in" operation...
The 40LF220 had a lower current capacity but was designed for a long shelf
life of ten years, hence the bulk. So yes, the CR2032 truly fits this
application.
The format is standard for battery backed clocks on PCs, but was quite new
in the late 80s.
I will look at current costs for getting a batch of 100 of these tiny,
single layer PCBs made.
Couldn't the card have a battery socket so that only the battery need be
replaced?
