Review: These batteries work fine in an older Panasonic phone. - The original batteries failed to hold a charge and I replaced them with a set of Panasonic NiMH batteries which sometimes did hold a charge and sometimes did not. My conclusion is that not all NiMH batteries are the same. Thus, it is important to make sure that the replacement batteries have the same model number as the original batteries. Review: Great batteries if... - you only need rechargeable batteries. But it was cheaper for me to buy the replacement post cap which included a battery. ## Features - 1.2V 400mAh - Ni-MH Rechargeable - Compatible with KX-TGD220N, KX-TGD22N, KX-TGD223N, KX-TGD224N, KX-TGD225N, KX-TGE273S, KX-TGE274S, KX-TGE275S ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076L726W5 | | Amperage | 1.2 Amps | | Antenna Location | Phone | | Battery Capacity | 400 Milliamp Hours | | Battery Cell Composition | NiMH | | Battery Cell Type | NiMH | | Battery Weight | 1 Ounces | | Best Sellers Rank | #242 in Cordless Telephone Batteries | | Brand | RocketBus | | Compatible Phone Models | KX-TGD220N, KX-TGD22N, KX-TGD223N, KX-TGD224N, KX-TGD225N, KX-TGE273S, KX-TGE274S, KX-TGE275S | | Customer Reviews | 4.1 out of 5 stars 859 Reviews | | Manufacturer | RocketBus | | Model Name | RocketBus BK 40AAABU | | Model Number | BK-40AAABU | | Number of Batteries | 2 AAA batteries required. | | Recommended Uses For Product | Phone | | Reusability | Rechargeable | | UPC | 680063060977 | | Unit Count | 2 Count | | Voltage | 1.2 Volts | ## Product Details - **Number of Batteries:** 2 AAA batteries required. - **Brand:** RocketBus - **Battery Cell Composition:** NiMH - **Battery Capacity:** 400 Milliamp Hours - **Recommended Uses For Product:** Phone ## Images ![RocketBus 2 BK-40AAABU Replacement 1.2V 400mAh Battery Packs for Panasonic Cordless Phone Handset - Image 1](https://m.media-amazon.com/images/I/61YgpOFnfML.jpg) ![RocketBus 2 BK-40AAABU Replacement 1.2V 400mAh Battery Packs for Panasonic Cordless Phone Handset - Image 2](https://m.media-amazon.com/images/I/7114Dkh5g4L.jpg) ![RocketBus 2 BK-40AAABU Replacement 1.2V 400mAh Battery Packs for Panasonic Cordless Phone Handset - Image 3](https://m.media-amazon.com/images/I/71LgqJtMTkL.jpg) ![RocketBus 2 BK-40AAABU Replacement 1.2V 400mAh Battery Packs for Panasonic Cordless Phone Handset - Image 4](https://m.media-amazon.com/images/I/71ihnpi6OjL.jpg) ![RocketBus 2 BK-40AAABU Replacement 1.2V 400mAh Battery Packs for Panasonic Cordless Phone Handset - Image 5](https://m.media-amazon.com/images/I/71tFC4Um2+L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ These batteries work fine in an older Panasonic phone. *by H***N on March 30, 2022* The original batteries failed to hold a charge and I replaced them with a set of Panasonic NiMH batteries which sometimes did hold a charge and sometimes did not.
