Orbus 12V 100Ah Batteries Lost Performance and Became Almost Unusable

On July 19, 2024, I purchased two Orbus 12V 100 Ah gel deep cycle batteries through N11 (Order No: 201976982633). I have been using these batteries in my hobby garden to power a refrigerator, a television, and LED lighting. Since installation, there have been no changes to the system, and I have used them according to the instructions without any physical damage. At first, the batteries easily met my energy needs until the next day. However, over time, their performance declined rapidly. While I initially experienced no interruptions, in the following months, the power began running out completely around 1–2 a.m. Currently, even when running the refrigerator intermittently with a timer, the batteries last only about five hours before fully draining. Compared to their initial performance, there is now roughly a 10-hour gap, making the batteries nearly unusable. I have not yet filed a warranty claim, and I paid a total of ₺10,138 by credit card. I request that my batteries be replaced with new ones that perform as they did on the first day.
