No better than Imedion
on September 9, 2012
These are good batteries, but not at all worth the price gouge associated with them. I purchased a package of four hoping to find some big advantage, but found none. When they arrived, I discharged them using a Maha CH-9000 at 500 mA. Just as other reviewers found, they had a little over 1000 mah. Then, I put them through the break-in cycle of the Maha CH-9000. Each battery's actual capacity came close to about 2525 mah, which is 125 mah above the stated nominal capacity on the packaging.
However, these batteries are not worth the high price because they offer no competitive advantage over the Maha Imedion Low Self Discharge 2400 mah batteries (which also are typically around 2525 mah when new).
In my experience, both Eneloop and Imedion's rate of self-discharge is consistent with their marketing, meaning that if you charge them and leave them in a drawer for several months, they will retain 80% to 90% of the charge.
Eneloop XX are around $18 or MORE for four batteries, while Imedions are around $12. That's a 50% premium! Since Eneloop has no competitive advantage over Imedion, the additional 50% cost cannot be justified in any way. The extra premium is a complete waste of money. You don't get anything at all for this additional 50%.
I have no personal affiliation with Maha (AKA Powerex). I've used and tested both the Maha Imedion and Sanyo Eneloop over the past few years. The Imedions are better batteries than the original Eneloops because Imedion's capacity is about 40% higher than original Eneloops, but the difference in price is usually less than 40%. Finally, Eneloop is offering a AA battery that appears to be nearly identical to the AA Imedion, but they are charging 50% more. There is no reason anyone should pay 50% more for a low self discharge 2400 mah Eneloop than what a low self discharge 2400 mah Imedion costs. In my experience, the quality of Imedions is at least as good as Eneloops, so the only way to account for the 50% premium is marketing hype. In passing I'll mention that Imedion low self discharge AAA capacity is still substantially higher than Eneloop AAA.
If these cost the same as Imedions then they would be 4 to 5 star batteries. At this price, they are at best 2 star batteries.
