These UL listed batteries are being used for backup power in my house. A set of 2 connected to 12k Sol-Ark grid tie inverter. In service for 4 years. Discover has discontinued this product. I would not hesitate in purchasing another Discover battery.
Had a slight problem with battery voltage between Sol-Ark and battery. But after a couple of cycles on the battery the problem went away. But did contact Discover and they guided me thru their Windows software that got detailed battery data from each battery. The main problem I have had is that the software runs only on Windows and I don't own a Windows computer.
The batteries perform well and to spec when needed during a power outage.
Yes, these batteries are more expensive than others. I was looking for a battery that would provide years of trouble free service and had to be UL listed.
