Apc Ups Battery Light Flashing Green And Red

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.

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.

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.

This is the second time that I have replaced the battery for my UPS. I am very satisfied with APC.

The battery in my UPS died and APC was able to have a replacement to me in 3 days. I’m very pleased.

My UPS APC Back-Ups (I have five) have been protecting my computer for more than fifteen years now. Even though there are newer models, I don't need any better than I have. I am very pleased to know that APC provides support and batteries even for what I assume are "legacy" UPS. The ease of finding the correct battery and sending the expired battery back to APC had always been a real plus for me as I am disabled and don't drive. In an era when "just buy a new one" seems to be the usual corporate approach, I appreciate APC.

I’ve had this battery for a while now and wanted to have a second one for when more light is needed. The battery has a small indicator light (red = charging / green= fully charged). Works perfectly with the PX1R flashlight!

You will not be disappointed with this little battery, in fact get two so you can have a charged one ready to go when you need it. The battery has a red light for charging and a green light when it is charged. Really great

Love the brightness, weight, and battery life. Only thing I'd change is to have a red or green light be actually integrated into one of the modes instead of using the plastic cap lens things that are included. Im sure I'll end up losing them but they're a neat idea i guess.

Charges the battery quickly. Power charging light changes from red to green when complete. Easy to store in our small camera case because plug prongs swivel sideways into body of charger. So compact it is too easy to misplace!
