Customer Reviews

the science behind the fit problem
I also ran into fit problems using these adapters. My AA rechargeables fit nicely into these shells, but the shells were too fat to fit into my camping lantern which uses 4 C cells. Saddened, all I could do was get out my trusty micrometer and begin to take data...

The Lenmar shells (at least the ones I bought) measured 1.02" in diameter. A Energizer battery measured a slim 0.985" and a Duracell measured 0.99". An Eneloop C adapter measured 0.98" in diameter. So the Lenmar adapters are definitely fat compared to the competition.

But here's where Paul Harvey would say "now for the rest of the story...". When I checked the ANSI standard for C batteries, I found the spec allows diameters between 0.98" and 1.03". So the Lenmar shells are within spec. The guilty item is, in fact, my camping light. (This is the type of insight you get when hard science types take to writing these reviews).

What to do? If your batteries will be packed shoulder-to-shoulder in a battery compartment with a tight squeeze, you're probably going to have to pony up for some (pricey) Eneloop upsizers. Otherwise I think you'll be happy with these Lenmar adapters. Maybe you can buy some of each and that way you can power any device while saving the environment and some $$$ at the same time.

great product
This is a terrific product - it's so nice to not have to go looking for a C battery - just pop in the AA (which I always have around) and go!

Awesome Lenmar C-Shell Battery Adapters
I bought about 3 to 4 packs of these Lenmar D-Shell Battery Adapters for my touchless trash cans and emergency items. I love them. We have an emergency closet and had bought alot of Rechargeable AA and AAA batteries. We have alot of items that you can wind up such as Emergency radios and flashlights, but we bought the adapters to convert our AA batteries into D-batteries for backup. We also purchased a few packs of Lenmar C-Shell Battery Adapters for our Electric train and various items. We have saved alot of money by replacing all our regular batteries with rechargeable batteries.

GOD Bless!
