I don’t know exactly, I’ve never paid much attention to how long they’re lasting. They seemed to be dying quicker of late but I’d had an issue with a dying cell. (TBF, I’ve had them for donkey’s years and they owe me nowt.) The nice thing about that charger though is you get an individual readout for each cell, so you can see what’s going on with them. There’s also a revive function which can sometimes renew elderly batteries.
The point of the regular Eneloops isn’t that they last longer in capacity terms, but rather that they don’t lose charge over time. Handy if you play less frequently and means that your spare set are already fully charged. If you’re swapping ordinary rechargeables with cells that were last charged a month ago they’ll be half flat before you’ve started.
That said, there is also an Eneloop Pro which is higher capacity. They’re not cheap though, for the price I’d rather have two sets of standard Eneloops then I’ve got a charged spare.
