at Home Depot, 2 pack was just under $8, 4 pack was $10.xx, 6 pack was $13.xx. I was tempted to buy the 4 or 6 pack until I saw
that the batteries in the 4pack was made in Malaysia, the 6pack was made in China and the 2pack was made in Japan. I bought the 2 pack…
unfortunately mine is payed up for 9 more months —- things like years of loyalty means nothing to these companies anymore — my first year of prime was $69.99 —I can’t remember how long ago that was
Every other year I order 5 or 10 packs of all the common lithium button cells from Aliexpress, and they cost $2 or less. Sometimes the batteries run 70% as long as the brand names, but I get 10 for the price that I would pay for one locally. For some devices if the batteries are hard to replace, I pay extra and order Energizer or Duracell from Amazon.
It's been listed since 2017 at best, rated at 700 lumens, and it's driven at 2.4 amps, as the KD listing says. No way can it do 700m (meters) like the Amazon listing says - Ali store says 200-300 meters.
For $10, probably still a good deal. Maybe that wrist holder is worth the $10 alone. Reviewer on Ali says it requires long (protected) 26650.
