Review: The battery works fine and completely transforms the usefulness of the radio - The battery works fine and completely transforms the usefulness of the radio, however, more should be done to ensure buyers can use normal off the shelf batteries. I can't yet comment on the run time of the battery, quoted as 12 hrs, I'd well believe it. I've used it for hours and not run it down. I've charged it once since I got it but I don't get the chance to use it as much as I'd like. One thing in the instructions that worries me is that they recommend to charge the battery even after using it a short time however, lithium batteries do not like to be stored at full charge for long periods and will almost certainly reduce the life of the battery if left plugged in most of the time fully charged. Best to use it for several hours and charge it fully and then use it again. I'm happy I purchased the battery, it's just a shame Roberts waited so long to make it available.
Review: Rare add-on for an Internet Radio, and very thin look, easy installation - It was hard to find an Internet radio with battery (others call it mobile phone as if there is WiFi, there is power)... but with this add-on I was able to deliver my sister's all wishes. Believe me, it is not easy.

### ⭐⭐⭐⭐⭐ The battery works fine and completely transforms the usefulness of the radio
*by M***E on 6 December 2016*

The battery works fine and completely transforms the usefulness of the radio, however, more should be done to ensure buyers can use normal off the shelf batteries.

### ⭐⭐⭐⭐⭐ Rare add-on for an Internet Radio, and very thin look, easy installation
*by P***R on 9 January 2020*

It was hard to find an Internet radio with battery (others call it mobile phone as if there is WiFi, there is power)... but with this add-on I was able to deliver my sister's all wishes. Believe me, it is not easy.

### ⭐ Roberts for richer sound, what else!
*by F***S on 22 July 2019*

To power up Radio 12 months on, and I regretted having given a thumbs up for the battery pack! this item was purchased by me in March 2019, but by January 2020, when I needed it most, it badly let me down. The pack was no longer charging, and button at the base moved but did not connect.
