For use with eneloop Ni-MH Rechargeable AA Batteries

eneloop battery spacers allow eneloop AA battery cells to be inserted and utilized in 'C' and 'D' size battery applications. The battery cells maintain their original eneloop AA cell performance characteristics including 2000mAh typical (1900mAh min)*, up to 2100 recharges**, and hold 70% of their charge for up to 10 years, (when unused and stored correctly)*.

(The 'D' size adapter comes with a base place that requires tightening). Once the charged AA cell is inserted into the spacer it is ready to be used in the device.

    5.0 out of 5 stars Compared to the other knockoffs these Eneloop C Size Battery adapters are fantastic!!
    Reviewed in Canada on January 3, 2022
    There are only one problem with these C size Adapters and that is the very thick wrapper that solidly encases the adapters so much that it is nearly impossible to unwrap.There is still a x-ac-to knife score mark on my thumb as they slip off the thick wrapper slicing across my thumb. Other than that one complaint the envelop AA battery simply slides into the casing and that is that; no unscrewing a cap and no unhinging the case. It is a solid single piece case that makes the AA battery feel like a C Size battery. Excellent and finely crafted case. There are so many devices that still uses C-size batteries these days, my hand waving sensor garbage can uses 3xC-size batteries, my Alessis Drum kit uses 6xC-size batteries and my sweater shaver uses 4xc-battery. Save your money and don't buy the knock offs buy cheap buy twice.
