I have been testing many different brands of disposable batteries with some budget equipment, this is the budget light forum after all :) I have been buying from pound shops & eBay.
I use a ZKE Tech EBD-M05, comparing some with tests done by HKJ my results are always slightly lower, would be interesting to know if anyone else has one of these and if they have tested the same brands I have, not 100% convinced on the accuracy of the device but the results may be useful to someone so here they are,
