What is the mAh rating of standard alkaline pile batteries, the non rechargeable kind?
So, I've had these four aaa batteries, two sets in parallel, they've been lighting this LED for two weeks now and they show little sign of weakening ( green light is not getting any weaker ). they were supposedly dead at the time of their use - they had lost greater than 10% of their voltage.
Anyone have any ideas on the mAh rating of standard batteries? any links? ..anything at all other than the book about "understanding batteries"?
Wikipedia is your friend (the answers therein are NOT always completely verified, but I've compared this graph against another I found on the 'net and it had silimar values).

P.S. What's the current draw of the LED?
By characteristics, 20ma. ..
but I've not measured across the leads.
