Yes, I have also found it hard to find data sheets for batteries. It seems that manufacturers like to keep their information secret. I found it similar when looking for specifications for outdoor clothing. For example, try having a look at the data for Gore Tex fabric. You have to look very hard indeed to find the information on how waterproof the fabric is!
I have found some indications of PP3/MN1604 capacities.
Duracell ProCell - about 550mAH
Energizer Industrial - about 600mAH
Of course these numbers don’t mean very much, it depends upon how the battery is used (tested).
I think I will just go with the Philips Extreme Life, as this has proven capability!
I will post some pictures soon of my rig. I don’t have my camera card reader with me at the moment.
I just applied a fresh 9V battery to my latest creation and I was pleased to hear some of those strange sounding beeps coming out of the earphones. G4FKH was the first station heard on my new RockMite.
I don’t think I’ll get any where near 243 QSO’s! That is a lot of QSO’s on a single battery and it seems from your current voltage that the battery is only about half empty!
In reply to G3CWI:
Congratulations Richard. I gave you 599 because you were 599! Remarkable signal for the power level used. Your antenna must be quite efficient.

My congratulation to you G3CWI Richard for this great achievement.
243 QSO on a 9v PP3 is awesome. Will be hard to beat.
But I try, But since you still have a lot more in battery it may be vy difficult.
Tanks for photo of the Rig. Any name?
Best of luck OM Richard
In reply to G3CWI:
Good signal from you today Richard, deep QSB at times but a good 579 on the peaks. Heard you yesterday on 2m FM whilst you were mobile, about 56. Obviously you didn’t hear me.

This battery will not beet the record. To much time calling CQ. Wasting mA from battery. But still try it to the bitter end.
