This
Sanyo Eneloop Super Power Pack Kit (SEC-N16SETGEN) looks almost identical to the original
eneloop Power Kit which I have reviewed more than three years ago. The only difference is that the 'Super' Power Pack contains four extra eneloop AA cells, stored inside the charger. As of this writing, you can get an
eneloop AA 4-Pack for less than the price difference between these two power kits. So you have to decide whether it is worthwhile to go for the 'Super'.
All batteries in this package are the first-generation eneloop cells. During the past four years, I have been testing/using 1st-gen eneloop cells, together with several different brands of low-self-discharge NiMH cells (including
Rayovac Hybrid,
Kodak Pre-Charged,
Duracell Pre Charged,
Sony Cycle Energy Pre-Charged, etc.) I can say with confidence that: eneloop cells are the most reliable and consistent among all brands.
Sanyo has introduced the new second-generation eneloop cells about one year ago (available in this
Costco package). However, both new and old cells have exactly the same capacity ratings:
- AA cells are rated as 'Typ 2000mAh, Min 1900mAh'. Actual measured capacity, using my old
La Crosse BC-900, is higher at about 2100mAh on the average.
- AAA cells are rated as 'Typ 800mAh, Min 750mAh'. Actual measured capacity is about 835mAh average.
Some advertised improvements of the new eneloop cells looked impressive on paper, but marginal in real life. For example, the new cells claim to have lifespan of '1500 cycles' (vs. 1000 cycles for 1st-gen). But note that even if you recharge your eneloop cells twice every week, it will take about ten years before you can realize the difference in battery lifespan.
The Sanyo MQN06 4-cell charger (included in this and many other eneloop packages) is a big let-down. Here's what I don't like about this charger:
- It charges in pairs only. This is very inconvenient for appliances that take odd number of cells. If you try to charge an exhausted cell together with a half-full cell, the charging process stops as soon as the second cell is full, which means the first cell is still half-empty.
- The charging current is very low: 300mA for AA cells, 150mA for AAA cells. That means it take about 7 hours to recharge a pair of exhausted eneloop AA cells.
- If you leave a pair of charged cells in an unplugged MQN06, there is a leakage current of 0.5mA. This means a loss of 12mAh per day. In other words, a set of 2000mAh cells will become exhausted in about 5 months. That wipes out the 'low-self-discharge' benefit of eneloop cells.
Bottom Line:
This Sanyo eneloop Super Power Pack is worth considering _if_ you can make use of all components in this package (including the C- and D-cell spacers). Otherwise, you should consider a package that comes with a better charger, such as the
Sony Cycle Energy BCG34HRE4KN, and then buy more Sanyo eneloop cells as needed. This SONY charger can handle each cell individually, and it can be used to recharge any other brands of LSD cells.
