 Inexpensive way to use rechargeable AA cells for D-cell applications Sep 09, 2007
By NLee the Engineer
If you have some power-hungry applications that require D-cells, you can usually save money in the long run by using rechargeable NiMH cells instead of alkaline cells. One approach is to buy a set of AA to D-sized adapter shells, and use rechargeable AA NiMh cells in those. This is the cheapest method because AA NiMH cells typically cost less than ten dollars for a package of four, and you can use low-cost AA charger for them (instead of buying another charger that accepts D-cells).
However, don't expect to get the same operation time as before when you were using alkaline cells. This is because the capacity of a typical NiMH AA cell is only about 2500mAh. In comparison, a typical alkaline D-cell is rated at about 20,000mAh for low current applications. At higher current, the actual capacity may drop to half. But this is still four times as much as that of a NiMH AA cell. In other words, you can only expect one-quarter the operation time after switching to NiMH AA cells.
There are rechargeable NiMH D-cells available with capacity up to 12,000mAh. Those cells can out-last alkaline D-cells in large current applications. However, those cells are expensive (around $25 for two) and you need special charger that are designed to charge high capacity D-cells. (Most low-cost chargers, even those that can accept D-cells, cannot fully recharge cells with capacity greater than 3000mAh)
Finally, be carefull not to fall victim to fake D-cells offered by Energizer and Rayovac. Those are just 2500mAh AA cells enclosed in larger D-sized cases. Prices of those fake D-cells are often ridiculously high, even though you still get very short operation time from those. Plus you need to buy a charger that can accept D-cells.
All things considered, using AA cells in D-sized adapters is still a good approach. Just make sure that you lower your expectation, and DON'T PAY TOO MUCH for those cheap plastic shells.

 Do not work well Jan 15, 2008
By I. Boys
These have failed to work for me in every item where I have tried to use them. The problem was that they did not make electrical contact with the metal springs inside the battery compartment. If you compare these adapters with a real D size battery, you will see that the typical real battery has much larger metal areas for the springs to touch.
It's a nice idea and I'd love to find some adapters with a better design but these unfortunately fail the test. Buyer beware.

Gets the job done, barely Feb 10, 2009
By ShoppingSmart
I've used a similar product by Panasonic which was MUCH better made, but I haven't found the Panasonic brand adapters sold outside of a Costco rechargeable battery kit.
The 4 Lenmar AA-to-D adapters do work but they are inconsistent in how well your AA batteries fit inside. 2 of the 4 adapters worked normally for me while the other 2 were too loose or the AA battery didn't snap into place when inserted - and I tried several AA batteries with the same results.
These Lenmar's are cheaply made but they will work. I don't recommend putting these adapters into service where you're going to have to change-out batteries all the time.

 Works as good as my Eneloop spacers. Apr 22, 2011
By Nuknuk
Most of my battery spacers are Eneloops that came with the batteries. They are available separately but generally pricier. The Lenmar is good enough. My "AAs" batteries fit them. All you have to do is push it from the bottom and it locks in the spacer with a satisfying click, just like the Eneloops.
The label is just a sticker that goes around the cylinder which gives it a cheap feel on it. You might not also get the same label as the pictures shown as I got a different gray/silver label instead. But what is important to me is that it works, not defective, and the money savings. I'll buy it again unless I find somebody else comes out with a better product and a better deal.

 Works Great with one slight revision Mar 12, 2011
By Michael E. Richardson
The rechargable batteries snap inside the shell. You get 4 of these in a pack. All you need is
a penny to make them work once you load them in a Maglight flashlight. AA batteries do not have a large enough metal contact area on the end. The maglight coiled cap, therefore, fails to touch it. Just stick a penny on the end of the last battery in your maglight, and it seems to work very well. I'm very happy with my purchase. Plus, I saved money over the Sanyo brand D shells.
