[QUOTE="Vaal, post: 1124081, member: 24036"] A couple of years ago, I used duck tape and webbing to tie 2 18A/hr batteries to the top of a 1000w ups and brought the 2 wires out of the unit to the batteries. It worked quite well because you have 12v Dc, 24V Dc and 230v AC in 1 portable package. I could even run my 750W baby grinder from it but in hind sight, I don't think any motors like a modified sine wave supply very much. Strangely my neighbor wanted to watch TV and my powersupply didn't want to work with his flat screen tv but it did work with his old crt Tv. The batteries later bombed out after a while due to the onboard charger was too slow and couldn't charge the batteries fully. To get rid of the irritating mains failure buzzer you open the cover, remove all power a d the just rip the buzzer out, if that is too brutal you can stick some prestic on the buzzer. In hindsight I will put a inline fuse in the supply cable close to the battery just fore safety sake in case of a short ore something. [/QUOTE]
