This battery was the wrong size for the rhythm p2! I sent it back and I want to exchange it for the correct size battery! USPS shows it has been delivered to your business! Please let me know for sure if you received it or not and what we are exchanging it for! Sharon Smith
I had bought these batteries from another company for twice as much. They did come two days late. They work fine. I will buy my future batteries from here
