What buyers say about 2 Energizer CR1620 Lithium 3V Coin Cell Batteries
I can't say how long the battery will last, but it's a good thing that the packaging isn't child proof, as these batteries are a choking hazard for the little ones.
I don't have to buy a whole pack when I only need one or two, so I'm happy to see the quantity of two.
I ordered a few Energizers because I needed a small number, but the shipping was long and it took ten days for them to arrive.
The battery works in an old watch.
I no longer have to open my car manually because the batteries arrived quickly.
