I’d like to purchase a replacement battery for my U400. One has gone missing, and I’m swapping from another lock. There is currently a “deluxe kit” available on the Apple Store which has a spare, but I can’t find a reference to a replacement/spare anywhere. Charing takes a really long time. I’d actually probably buy two so that I always can charge the spare and swap it out as swapping will keep things up and running.
