Fit the phone perfect. The great thing about this battery, was that it did not die due to the power outage. Every other battery I have purchased for this cordless phone would loose all of its charge as soon as the power went out due to storms. This battery did not. Our power was out for approximately eight hours the other day, and when it came back on, the phone worked without having to recharge it. I am not sure why this one holds the charge, but it’s fantastic. Review: Good replacement for my old Panasonic cordless phone - The battery pack was very well packaged and was shipped promptly. It took about a day to fully charge, which is not unusual. It seems to be working just fine. ## Features - Kastar Battery Replacement for Uniden BT800 BT-800 BT-905 BP-800 BP-905 Battery - Battery Type: Ni-MH; Battery Voltage: 3.6V - Battery Capacity: 1600mAh - Package Includes: 1 Battery - Replacement for GE, Cobra, Panasonic, Sharp, Sony, Uniden, Again Again, ATT, Casio and Sprint Cordless Battery ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00ESQ1C5O | | Antenna Location | Cordless Phone | | Battery Capacity | 1600 milliampere_hour | | Battery Cell Composition | NiCAD | | Battery Cell Type | NiCAD | | Best Sellers Rank | #669 in Cordless Telephone Batteries | | Brand | Kastar | | Customer Reviews | 4.4 out of 5 stars 145 Reviews | | Global Trade Identification Number | 00726046639232 | | Included Components | Battery | | Item Weight | 1 ounces | | Manufacturer | Kastar | | Model Number | 231867-UL114 | | Number of Batteries | 1 AA batteries required. | | Recommended Uses For Product | Cordless Phone | | Reusability | Rechargeable | | UPC | 726046639232 | | Unit Count | 1 Count | | Voltage | 3.6 volts | | Warranty Description | 18-Month | ## Product Details - **Number of Batteries:** 1 AA batteries required. - **Brand:** Kastar - **Battery Cell Composition:** NiCAD - **Battery Capacity:** 1600 Milliamp Hours - **Recommended Uses For Product:** Cordless Phone ## Images ![High Capacity Cordless Phone Battery Replacement for Uniden BT800 BT-800 BT-905 BP-800 BP-905, GE TL-96560, Cobra, Panasonic HHR-P505 P-P501 P-P504 P-P508 P-P510, Sharp, Sony BP-T18 BP-T24 - Image 1](https://m.media-amazon.com/images/I/71WnCeC5P2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Holds a great charge, for long period of time. *by G***N on February 21, 2018* Fantastic battery.
