    Hi Guys, I am looking for a set of second hand batteries to use as back-up batteries on my 3kw infini hybrid inverter. As I understand they will not be used until a power failure. Looking at our load shedding history I will want them to provide 800W for two hours during load shedding (computers and admin stuff no real peaks) With our national electricity demand down by 10% and our office not working during peak hours I don't expect the batteries to be used more than say 20times in the next 3-4 years, so I will be happy if I can get a life of 3-4 jr's from the batteries. Any ideas or offers and do you think my reasoning makes sense Thanks God…
