On Amazon, the Arris Touchstone Modem Backup Battery 8 Hr has 4 out of 5 stars. While other backup batteries claim to last a little longer, most reviewers said the Arris Touchstone performed as expected, that is a full 8 hrs. Only a handful of Amazon reviewers claimed the battery failed to last as promised. This is a negative review on Amazon from a disgruntled customer who states her battery would not fully charge and only gave her about 25% of the expected battery life. She claims she tried to return it approximately two months after the purchase date, but the seller didn’t honor the warranty. In another review, one user cautioned to not install the battery if you are expecting bad weather and outages as it needs to fully charge when first installed. The majority of reviewers had great things to say, however, like “simple to install,” “worked through several power outages,” or “installed it and it’s been working ever since.”
The battery is a breeze to install. Once installed, it stays in the modem so it will be charged in the event it is needed. Below are the installation instructions.
To Install the Arris Touchstone Modem Battery Backup 8 Hr in your Comcast Modem (model Arris TG852):
- Locate the battery compartment on the back of the modem unit. With your finger, press then pull the latch open.
- Align the battery so the guidelines meet the lines on the modem, then slide the battery fully into the compartment until it snaps into place. If you don’t have it lined up properly, the battery won’t fully insert.
- Then, replace the door. If the battery was correctly installed, the battery light on the front of the modem will now be lit.
For less than $15, the Arris Touchstone Modem Backup Battery 8 Hr makes sense. Simply install it and forget it about it until you need it. If you end up without power, you’ll be convinced it was the best $15 you ever spent.
