That is why the batteries!

For once I''ve ordered without looking at the comments, just for the price.
The batteries come in a little plastic bag, no original packaging. I have indeed been the "Duracell Ultra" promised.
For now, they seem to suit my smoke detector, to see in time ...

Big downside: the delivery time! more than 10 days for me.
I, who wanted to avoid wasting time looking for a store that sell them ... Next time I will go to them myself (the photo printing shops sell!)
