Which is better for flashlights?

Both work in flashlights. The Rayovac pack costs far less per cell, so it is the better pick if you run flashlights often.

Duracell rates its Coppertop cells for 12 years in storage. Rayovac rates the Ultra Pro for 10 years.

Is the Duracell 4-pack worth the higher price per cell?

Only if you need a few cells or want the longer storage guarantee. For volume use, the Rayovac 24-pack is cheaper per battery.

Yes. Both are standard AAA 1.5V alkaline cells at about 10.5 mm diameter and 44.5 mm height.

Which has more capacity?

Duracell lists 1,150 mAh and Rayovac lists 1,100 mAh, a small difference that rarely matters in low-drain devices.

Are either rechargeable?

No. Both are single-use alkaline batteries and should not be recharged.
