No wonder I have been convinced what crap rechargeble batteries are all this time.
that circuit cannot charge NiCd or Lead/acid battery to any reasonable capacity, maybe 2%
Most recently I started with Ni-Mh batteries when I got a digital camera which came with charger and 2 batteries. after the first 2 or 3 times recharges I started noticing that I can't make more
than 5-7 pictures before it shuts down because the batteries are weak. I don't think I ever had a charger that was any good.
I think I measured the current while using the ZOOM it was sucking nearly an amp
if the camera draws that much current then they should at least make room for 4 batteries but I haven't seen a camera that takes 4 batteries yet.
