All of the small 12volt 5.4AH UPS batteries seams to be working and has taken a good charges. Now i put them back in the plastic case, and back into the HP/Compaq R3000 XR UPS system.

My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.
