Hello,
I've got a 48 way Sirius which has served me well for many years. It has got analogue and DMX outputs. When I last switched it on the memory was corrupted and various LEDs were illuminated. I whipped the back off to discover that the 3.6v memory protection battery on the Main PCB was drained and refusing to recharge. I have replaced it (twice, just in case) with a new Varta 3.6v 110ma Mempac battery which charges fine but drains within 3 days. Any ideas which component might be causing this problem?
