Sorry to hear about this experience @dwayneneal. Your Keypads should definitely be holding a charge for longer than a couple days, and should operate as intended when plugged in.
Please ensure these Keypads are located within range of the Base Station for optimal signal and operation. If you believe your Keypads are fully charged and abruptly going offline or draining battery, I recommend reaching out to our support team for in-depth troubleshooting. Feel free to let us know how it goes!
