Yeah, name brands like Energizers are consistent but slightly worse than Eneloop at roughly the same price.

I actually made a battery tester as a hobby electronics project. Fully dumps the energy while measuring mAh and seeing some measurements of internal resistance.

Something I did notice was that crappy battery chargers can permanently damage even Eneloops. So don't cheap out on the chargers either.

The high speed chargers (2 hours or less) are on the edge of what is safe and could permanently damage a cell. The 4 hours or slower chargers are just way more reliable. There's probably someone out there testing different chargers (trying to find the safe fast chargers) but given how cheap NiHMs are (even the "expensive" Eneloops), it's just easier to use 4 hour or 8 hour chargers and have masses and masses of extra NiHMs laying around.
