No compatibility issues with the equipment.
Actual load: an apparatus in which I use this kind of battery provides an assessment of the load. For JPS batteries indicates 80% when I install a new one, while the other Duracell and Varta I'm 100%.
It is therefore likely that these batteries are less powerful than their premium competitors to 3 euros each, but less than 1 euro, even for 80%, it's still half the price.
I will amend that comment later if I observe a premature battery depletion.
