[QUOTE="chrisc, post: 1123976, member: 746"] APC is one of the better brands. Consider adding another battery set. The 1400 model uses 2 x 7 a/h 12 volt batteries connected in series You can use 2 x 9 a/h, or better, 2 x 18 a/h. Don't go crazy and use anything bigger Open the UPS by removing the yellow battery connector, then removing the 4 screws at the back and one under the front cover. Then undo the 2 screws now visible to split the cover If you are not using the telephone socket, you can use this to lead out 2 flying leads to connect to [B]supplementary[/B] batteries Solder the leads to the battery push-on terminals. There is not much vertical space above the batteries or you could use a female-male push on clip I did this operation for someone on this same model and his now lasts well beyond the 150 min load-shedding period [/QUOTE]
