So far I've bought three sets of 4xAA Konnoc batteries. The first two sets worked fine for my two cameras, in fact their battery life seem really good. At that time, I already noticed that the batteries are exceptionally fat and at times difficult to remove from the cameras.
The problem came when I bought the third set for a newly bought slave flash. The compartment is much smaller and the batteries won't fit at all. Remembering a fellow ClubSnap member saying the batteries started to fit better after prolonged usage and the label came off, so I proceeded to peel off the label.
I don't have much knowledge with batteries, but I suppose the labels aren't supposed to be peeled off. As I plugged the batteries in and turned on the flash, it didn't work. So I took out the batteries and in the process gotten a VERY nasty burn on my two fingers. The batteries were SUPER hot! Needless to say, the flash go up the lorry liao, and I hope I can manage to get an exchange. Otherwise, what an expensive lesson for me.
Now, even if you are smarter and didn't peel off the label, the Konnoc batteries might still not fit into some of your equipments. With so many other brands of rechargeables out there, I say avoid this brand until they work out that extra calories on their batteries.
