Spectrum Modem Battery Light Flashing Blue And Red

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

My APC UPS sounded off every few hours with beeps and a flashing red light to let me know it was time to replace the battery. I ordered online and the battery arrived sooner than expected. I installed it and it's been working fine since. The part I especially like, I didn't have to shut everything off to install.

Bright white light is very bright. Red/red-flashing light is cool -- not sure if I'll ever use it. Good fit and balance (with batteries in back). Lightweight and comfortable. Looks suitably geeky. Very happy with my purchase.

Modem has been out performing the Spectrum one I had

Works as advertised! It's responsive and easy to use. My only minor complaint is the flashing blue light which can be a little annoying in a dark venue But, I realize there has to be some way to know that it's on

The color spectrum is spot on not blue or yellow...pure white. Also you can light up a large room just shining up on the ceiling for security reasons. My only wish was if surefire made a second mode for strobe. Shipping was great solid packaging fast and accurate

I have the Spectrum Gig network. The upload speed is much better now with this modem.

Solved my problems with my Spectrum modem by replacing it with this one from Netgear!

As many others mentioned in the reviews, these batteries are now new old stock, as the newest ones were made in 2022 and will arrive completely discharged. DO NOT give up on them - the charger will initially show an error (chamber and calibration light flashing) - keep taking the battery off and putting it back on, and eventually it will start to charge. The key is to not leave it in the charger if the charger is showing the error code, you have to remove and replace the battery until the charger shows that it is charging (chamber light and 50% light flashing). After a few hours the 50% light should glow solid and 80% should start flashing, and eventually it will charge fully

I bought this a month ago when the battery died (I unfortunately did not notice the low battery flashing light indicator). The replacement battery arrived very promptly, was easy to install, and my backup is operational again — and just in time because a tornado hit here a few days later and I lost power for 8 hours.
