I have bought batteries in bulk for years because, (especially from Sam’s, name brands) are just so much more cost efficient. I bought C’s & D’s. There was no perforated opening on the backside for easy access. It took 30 minutes and a sharp knife to get into the compartment. I should have ended up in then ER room for stitches! I think from now on I will go down to the local hardware store to purchase the batteries I need. I will be rethinking my battery buying in the future.

Every battery in the pack was dead. So frustrating. waste of money.
