Panasonic Four (4) X CR2450 Lithium Coin Cell Battery 3v Blister Packed

The batteries had the correct amount of volts and they fit and worked.

Arrived quickly but the packaging is Chinese and has no manufacture or use-by date, which is unusual.Voltage of the cells were only 3.2V which makes me think these are either old cells or not genuine quality Panasonic.I got a Duracell coin cell out of my drawer (which went out of date last year) to compare and it had a much healthier 3.285V showing that even when a cell is out of date it should be closer to 3.3VThese are cheap enough but I wouldn’t trust them in something I rely on, like a dive computer, welding helmet or car key. I don’t fancy drowning, going blind or having an unplanned walk home.

Good
