3.0 out of 5 stars A Man's Got to Know his Batteries' Limitations, November 21, 2010

The two rechargeable batteries in this package (SANYO Eneloop Spacer Packs with 2 AA with 2 D-Size Spacers) are the best-quality low-self-discharge NiMH cells currently available. The two spacers are made of high quality plastic without any rough edges, and they looked great. The price is also very reasonable. So normally I would call this a good deal. However, if you intend to use them in appliances that accept D-cells, please beware of the following limitations:

1. The capacity of each eneloop AA cell is just 2,000mAh. In contrast, capacity of a typical alkaline D-cell (such as the Energizer E95) is rated at around 20,000mAh when delivering a low current of 50mA. For a larger load current of 500mA, its capacity drops to around 10,000mAh. Still, this is five times the capacity of eneloop AA cell. What this means is that: you need to remove and recharge your eneloop cells five times more frequently, compared to when using alkaline D cells.

2. The base of the D-spacer is hollow. It uses the negative terminal of the AA cell for contact. The battery compartment designed for normal D-cells typically have much larger springs, so the base of the AA cell may fail to make contact with the spring. Check the picture I uploaded to the Customer Image section, and you'll see what I mean. This problem can often be solved by inserting a copper penny or nickel between the battery base and the spring. But it does not always work.

There are some other rechargeable D-cell options available. For example, consider the Rayovac Platinum LSD NiMH D cells. This package is currently priced similar to the eneloop package, but it gives you two real D-sized cells, with 50% higher capacity (3000mAh vs 2000mAh). The down-side is that you'll need a battery charger that can handle D-cells.

If longest run time is your first priority, then consider buying full-capacity D cells such as the 9500mAh IMEDION D Rechargeable Batteries. Those are priced 3-4x higher, and you need an expensive charger that can handle full-capacity D-cells. (Most low-cost chargers cannot fully recharge cells with capacity over 3000mAh)

No matter which option you pick, using rechargeable batteries will save you money in the long run. You just have to know your batteries' limitations, and set your expectation accordingly.

We were really surprised to see that Sanyo Eneloop has devised a way to make AA batteries fit in all C and D products. We were doubly surprised that Sanyo Eneloop AA batteries can power our virtual walls for our iRoomba robotic vacuum cleaners, speakers, small lights, flashlights and other products.
What a great idea! I love the new ideas that Sanyo Eneloop is developing -- they produce by far the best rechargeable batteries on the market.

Have been using Eneloop batteries for a couple of years now for all the remote controls, video games, calculators, cameras etc. - they last a long time, the rechargers work great, and they do hold their charge, the batteries that have been sitting in reserve for awhile last just as long as those freshly charged. I have yet to use up an Eneloop so that it doesn't hold a full charge. The C and D spacer kits are good in certain situations but you still have a AA battery in there so they don't last as long in the device as a "real" C or D battery (flashlights are what we have mostly tried this in). They do tell you this in the fine print that comes in the package. But since they are always fresh you have something there to power your flashlight when the electricity goes off or any short-term need so it's great in that way and I recommend having some on hand. But for a camping trip or any extended use, get the real C or D batteries. I wish Eneloop made them, I would definitely buy them rather than disposable batteries!
