If anyone is interested I have a box of used but working RBC18 battery sets from APC UPS's. Basically they've been replaced as part of routine maintenance, they've been in use approx 2yrs. I need to know asap (today) if there's interest else they'll probably go off to recycling. They'd need collecting from our office in Peterborough. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG
