Review: Go for real deal. Be cautious of ultra cheap. - There were several of these on desertcart -- mine was indicated as "Sold by Sale Stores and fulfilled by desertcart" and shipped via Prime; it was pricier than some of the other options. YES, this is genuine -- or as close to it as it gets. Another reviewer posted video showing the difference between the cheapy fakes and the real deal: the one I got from desertcart matched his real one (the writing on mine is actually part of the white shrink wrap around the battery). When I picked out the old super cheap replacement battery I'd bought on auction elsewhere, it was just a white paper label stuck onto white plastic shrink wrap. Another difference was that the old replacement caused my phone's handset get warm while charging, and it lasted less than a year. This new battery pack doesn't get warm at all and holds a charge for at LEAST three days (haven't left the phone off its charger longer than that, so maybe it could even go further). Grateful to the advice here in being able to tell the difference between cheapy fakes and real deal, esp. since I experienced both.
Review: As Described - Received undamaged condition. Material design satisfactory. No missing parts. Material quality and strength good. Installs easily. Operates properly.

### ⭐⭐⭐⭐⭐ As Described

Received undamaged condition. Material design satisfactory. No missing parts. Material quality and strength good. Installs easily. Operates properly.

### ⭐⭐⭐⭐ Good battery for older cordless phones!
*by B***A on June 17, 2024*

I’v only had the battery for a month but this battery was easy to install and is working great so far! I’ll try it for a little while longer and then order another for my second handset. Only reason for 4 stars is because I don’t have long term data on its lifespan to give 5 stars.
