Excellent price. Quality is better than original battery.
Is better than the original battery. It has 3 times more mAh than the original. The battery comes with enough charge to last at least 5 hours without electric power. Its just an excellent battery.
Really can’t rate this battery pack until power goes out. Then will be able to see if the system stays charged the full 24 hours. It was at a good price and the same as the old which lasted 5 years, only time will tell.
This battery works great in my ADT system. It is half the price of the one quoted at Battery Plus. I will buy it again in 3-4 years when it cycle is over.
