The older generation, white ENELOOP were well. These are just excellent. I use them with cobra type photo flashes, recycling times are very short, a low self-discharge rate (whereas Ni-Mh large surfaces are flat all the time when it is needed, and significant autonomy . Where good alkaline batteries heat up really hard, Eneloop remain lukewarm. In summary, much better than the best disposable batteries and a very quick amortization because for two to four times the price of disposable batteries used 500 times this mini if they are normally treated. The consideration is the indispensable use of a good charger, count +/- 30 because the ideal is to charge batteries with each individual control. I must have sixty of these batteries, I prens care with good management to ensure rotation, it now would take me a second charger ideally to 8 positions
