Mighty Max Battery 12v 7000 mAh Compatible Battery for APC Smart-UPS SC 1000VA - 2 Pack

I bought these for my APC UPS back in November. This morning the power went out and the APC lasted less than 5 minutes. When I looked at the LCD on the APC, it shows the batteries are nearly dead. I have reached out to Mighty Max about replacements since they claim a 1 year warranty... we shall see...UPDATE: their customer service is top notch. They quickly sent out two replacement batteries. All they needed was the date code stamped on the batteries for their own research. Hopefully the new ones work better. Changing to 3 stars due to such good customer service.
