Great solution to use NiMH AA batteries in place of C batteries

- Reviewed in the United States on October 5, 2025Style: C SIZEVerified PurchaseThese are pretty basic, a plastic sleeve that slips over an AA size battery so they fit in place of a C battery. They work flawlessly in this regard, with the AA battery fitting inside snugly. The plastic feels strong, not like it will crush or fall apart easily, so I expect they should last a long time. They're working well for allowing me to use AA NiMH batteries in an old radio that takes C batteries, resulting in my not having to have specific batteries and a charger just for that radio. Well worth the price for that convenience.

- Reviewed in the United States on February 3, 2025Style: C SIZEVerified PurchaseAbout battery cell adapters.....
Adapters such as these are simply a sleeve to center an AA cell in a compartment sized for a larger C cell. In order to work, the contacts on the device must be able to meet with the smaller diameter ends of an AA cell. Several other reviewers mention this. With an AA cell in hand, you can generally "eyeball" whether this will work by inspection before purchasing. For spring loaded devices, pushing in the adapter with its AA cell will sometimes result in the AA cell pushing through the sleeve. With multiple cells end to end, this can be a frustrating task. This can sometimes be corrected by wrapping some tape around the AA cell to increase the friction.
If you can get this system to work, there are other considerations. An AA cell usually can't provide the amperage of a C cell so, some devices may deliver neither the brightness nor volume, etc. expected. Other devices may not work properly at all. Also, an AA cell can't provide the amp-hours that a C cell does thus, operating times may be shorter. I use these adapters with non-rechargeable Lithium AA cells (or, AAA cells, see below) in my seldom used equipment such as an emergency radio or lighted precision reticle since the Lithium cells are less prone to leakage, over time, than alkali batteries are, and, to my knowledge, are not available in C size yet. It seems the non-rechargeables are only available in AA, AAA, and 9v. That's where these are a good workaround.
Another alternative is this adapter which I have also used.
https://www.amazon.com/dp/B0851DLJ3T?ref=ppx_yo2ov_dt_b_fed_asin_title
Here a combination of multiple AAA cells can be used (in parallel) to replace a C cell in many cases equaling, or exceeding, the C cell's original capacity. While contact alignment is not generally the issue, size may be. If the device using C cell compartment is tight from a diameter perspective, sometimes these adapters, with a full capacity of 4 AAA cells, will not fit or, will get jammed and difficult to remove. These adapters also introduce a third metal to the circuit. There is now the additional risk that different metals in contact with each other (essentially forming a "battery" in their own right) will begin an electrochemical reaction resulting in oxidative corrosion. Again, your mileage will vary.
Both of these adapters have their function and purpose. They may well work for you.
Hope this helps.
- Reviewed in the United States on October 14, 2025Style: C SIZEVerified PurchaseThese sleeves work great for using AA batteries in place of using C batteries
- Reviewed in the United States on September 23, 2025Style: D SIZEVerified PurchaseGreat product and service, highly recommend recommended!
- Reviewed in the United States on October 3, 2025Style: C SIZEVerified Purchaseworks great with rechargeable AA. Others have been too small
- Reviewed in the United States on August 8, 2025Style: C SIZEVerified PurchaseWish I knew these existed a lot sooner. When I bought my house the old owners left a few clock's behind. One required a "C" battery. I have a ton of rechargeable 2800ma AA ebl batteries for remotes, toys and controllers. I happened across these on pure accident. A AA battery fits nice and snug inside and it fits perfectly in the battery slot in the clock. The pendulum swings once again! Unfortunately the clock doesn't keep time.
- Reviewed in the United States on September 22, 2025Style: C SIZEVerified PurchaseThese didn't work. The AA batteries push right through the openings regardless of which way I turn them, and even though I was using new batteries, the item I put them in didn't work. Plus the way these slide around makes it REALLY difficult to put batteries in items that don't have fully exposed battery spots. If it weren't too late 🤦♀️🤦♀️ we would be returning them.
- Reviewed in the United States on August 12, 2025Style: D SIZEVerified PurchaseThe adapter to make a 'D' battery out of an 'AA' battery works as described. However, if you are trying to use these in a flashlight with a large spring contact in the bottom of the battery compartment it may not work. The 'AA' battery has a smaller negative terminal than a regular 'D' battery, and may not make contact with the flashlight spring if the spring coil has a greater diameter than an 'AA' battery negative terminal.
