AT Ni3615T30P3S534416 Battery Replacement WF720 Review

The battery was purchased for use in an At&t mobile phone base. The original battery has lost capacity. The new battery never had a good capacity and was almost completely discharged after a month of use. I had to reset the original battery, luckily I haven't sent it off for recycling yet. The device is working fine again, so the problem was definitely the new battery and not the device.

We haven't had our home phone service in over 2 weeks, thinking it had something to do with the lines. No there was a battery the whole time, I replaced it with this battery from Amazon and ta-da. Everything is back to normal, the phone works fine. This battery works for an AT&T WF720, it may have been installed incorrectly by other users or have a bad battery, but it worked for me. Hope this review helps.

Bought this battery for an AT&T phone system. The battery should work for the wireless phone system model number. However, after the first two days of successful feeding, the system stopped working and could not be charged for operation. The battery didn't seem to support or charge the phone even though all parts of the phone were connected. I wouldn't recommend it as a replacement for AT&T phones.
