What do you think is the best battery back-up on the market & do you think they are worth having?
I think the best battery back-up is APC Back-UPS 450 made by Schneider Electric. They store electricity even after a black out for the longest time and it's worth having it. The best battery back ups are from Japan, USA and Western Europe according to research conducted by ATT Bell Labs and IBM.
