Hi,
Just an odd co-incidence that another of todays posts also included that same type of big nicad battery stack for the rtc.
Would it not be better, cheaper even, to use a button cell - as mentioned by Maxim some inexpensive ones can last 11 years.
Can I ask the most obvious question - without meaning to cause offence - do you not think the name might be storing up problems with similar named companies?
If your prices are good, your good looking board should sell itself.
