Average Reviews:
(More customer reviews)To make a long story(*) short: these shiny "Rayovac 4.0 AAA" are low-self-discharge NiMH cells, similar to the old Rayovac Hybrid AAA cells. They are NOT the same as Energizer Advanced Lithium cells.
I have tested four of these Rayovac 4.0 AAA cells, using my La Crosse BC-900. Here are the results:
- Average capacity = 590mAh right out of the package.
- Final capacity = 770mAh after two more charge/discharge cycles.
This performance is consistent with that of Rayovac Hybrid AAA I have previously tested.
As of this writing, these cells are available at much lower price compared to Sanyo Eneloop AAA cells. That makes them a steal of a deal!
(*) Read my review on Rayovac 4.0 AA for the long story, which also explains why this product only deserves a 4-star rating.
[Update on Feb 25, 2010]
Data on long-term self-discharge rate: I have tested four each of Rayovac 4.0 AA and AAA cells, after 100 days of storage at approximately 19 degree C. The average charge retained in both sets were exactly 86% of original. This is consistent with the self-discharge characteristics of Sanyo eneloop and Rayovac Hybrid.
