Oops, my mistake they are not 2100. They are 2300 ! Energizer brand. I just bought them a month or two ago from Wal-Mart. They were pricey for a 4 pack but the 8 pack was a lot cheaper per battery. I'm thinking they were around $18 for 8. Barramus Where did you get 2100 ma? Jim Bensman "Nature Bats Last"
