APC ES 550 constantly clicks switching to battery for what it reads as electrical noise.

I tried buying a replacement battery but that didn't help. Lowering the sensitivity to medium helps but it is for a computer so having high sensitivity is probably better. Also, I got a Back-UPS NS 900M-CA and that seems to be switching over a lot less often but I don't know if that means the old UPS is now a dud or not. I don't know if it is a dud because I tried taking it over to my mothers place and plugged it in over there and it only switched over to battery for a sec or 2 every 5-10 min instead of pretty much constantly at my place.

Thanks

I really don't like bumping my own threads but there's been no reply since my initial post which was over a month ago so I hope this is alright...
