Energizer CR2 3V Lithium Battery EL1CR2T

My SLR camera kept dying mid-shoot until I swapped in these CR2s—three volts of steady power made a real difference. They've lasted through hundreds of shots without dropping off.

Bought these for my SLR camera and the consistent 3V power makes a real difference in flash recharge speed compared to the old ones I had.

My calculator was chewing through alkalines every few weeks, but this 3V lithium seems to run forever—the voltage reading is still rock-solid after two months of daily use.
