I wanted better quality batteries to use in my flashlights.

good quality.

Not that they aren't good quality, but next time I'll spend the extra money for real D Cells, the ones rated at 10,000 mah.

Great quality

I have not tried them but it seems like a good idea if they are decent quality, make all your battery operated devices save for those using 9V use the same size cells for interchangeability.

What poor workmanship and quality.

Good quality rechargeable batteries
