Here are all the batteries on our site we ID as being for Pentax digital cameras:
Digital Camera Batteries | B&H Photo Video The two brands are Watson and Pentax. The country of origin is either China or Japan, depending on the particular item.
SDXC and SDHC cards are on our site at
Memory Cards, SD Cards | B&H Photo Video. There are almost 200 items, from about a dozen brands. For some, the country of origin is China or Taiwan or Austria. I did not check them all.
B&H has not yet received any notice from distributors if/how prices in the U.S. will be affected by recent/announced changes in U.S. tariffs. I think it's worth noting that news about tariffs seems to be changing daily.
