They are very hard for seniors to open. If children were to come they are always put away in a drawer. I believe I ordered the regular package but came as child protected. ### ⭐ Impossible to remove batteries from new packaging. *by on Reviewed in the United States February 13, 2025* DO not buy. It is now impossible to remove batteries from the package. I have purchased this brand many times and in the past, there was a resealable flap in the back to remove the batteries. This has now been removed and there is a graphic to cut them out with a scissor. But good luck with that. The package is stronger than my best scissor. And unfortunately I discovered this 12 days after the return period expired. I will be throwing the entire shipment in the trash and have to buy another brand.Edit to this post...This problem is due to a ridiculous law called Reese's Law. Apparently an 18 month old named Reese swallowed a coin cell and died. So Congress and Biden enacted "Reese's law," requiring all coin and button cells to be in child proof packaging requiring tools to open and included hearing aid batteries. Unfortunately, child proof packages are also senior proof packages and most hearing aids are used by seniors. I'd write to my congressman but he's one of the dummies who sponsored it. I don't have a solution but all brands now seen to be in these new "legal" packages. Thanks, congress. ### ⭐⭐⭐⭐⭐ HEARING AIDS *by on Reviewed in the United States July 26, 2026* Work Great for hearing Aids, and a lot cheaper than what you can buy at retail stores. ## Frequently Bought Together - Rayovac Extra hearing aid batteries size 312.
