(More customer reviews)This package includes the new Rayovac "Hybrid" rechargeable NiMH AA cells. Similar to the Sanyo "eneloop", the Hybrid is also advertised to have low self-discharge rate, but not as low as that for eneloop. The eneloop is supposed to retain 85% charge in 12 months (when stored at 20 degree C), whereas the Hybrid is supposed to retain 80% charge in 6 months (no mention of temperature).
On the other hand, the capacity for the Hybrid is rated at 2100mAh, which is slightly higher than that for the eneloop (2000mAh). I have tested both brands and can confirm that both ratings are accurate. In actual applications, the difference in performances of those two brands is probably negligible. So it all comes down to price. Let's hope that the competition will drive down prices for both.

In my 2-month self-discharge test using four different brands of NiMH cells. Hybrid and eneloop came up neck-and-neck!
Room temperature: 60-62 degree F (16-17 degree C). All capacities measured are average of 2-cells.
- Sanyo eneloop 2000, purchased Jan 2007.
Initial capacity measured: 2070mAh
Capacity after 62 days: 1796mAh (-13.2%)
- Rayovac Hybrid 2100, purchased Jan 2007.
Initial capacity measured: 2155mAh
Capacity after 62 days: 1859mAh (-13.8%)
- LaCrosse 2000, purchased Jan 2006.
Initial capacity measured: 1902mAh
Capacity after 62 days: 1417mAh (-26%)
- SONY 2300, purchased Sep 2004.
Initial capacity measured: 2210mAh
Capacity after 62 days: 1309mAh (-41%)
So the Hybrid has slightly higher initial capacity and almost identical self-discharge rate compared to eneloop. This makes it a better choice especially if you can get it at lower price.
