In article , says... You may have been premature on buying the new battery. Typical battery life is about 6 years. typical batter life, in a residential setting, is between 2 and 5 years - according to APC Support technicians. I've seen batteries, new, last only 1 year in a setting with lots of power problems. I had to replace the battery on my APC Backup UPS Pro 650 after about 2.5 years. I concluded that it was running too hot - after moving the box to improve ventilation it is much cooler. Before the failure warning it was showing reduced capacity.

I have a number of APC UPS devices in my home and at work. I started
getting the nag message at home on my main PC. The battery lasted about 6 months after the nagging. However, one day the PC would not boot. I checked and the PSU was failed. I replaced it, and the second PSU made a sound and failed. I replaced with a third and bypassed the UPS and was back up. I had a router, cable modem, and such also plugged into this UPS. They started acting up. They would quit working, and the router kept loosing it's configuration. Ends up the problem was with the UPS and the old battery. I replaced the battery and all is fine again. The computer and all are back on this old UPS with a new APC battery. I could have saved some bucks if I'd of just replaced the battery when I was reminded to do so. While I used an APC branded battery (though it is 3rd party) we replace with other brands at work. I almost went with this Panasonic for $10 less; http://www.wholesalebatteries.us/rep...C-R127R2P1.htm But figured I'd go with APC incase something else was wrong with the UPS. |

Yes, I understand that the cheaper ones don't use the battery unless of
an outage, or dip. However, the power in my area is very unstable. The first month I had the UPS, it switched on over 100 times per the software counter. It's a little better now. I had 2 PSU's blow and other hardware instability while the bad battery was in place. Replace the battery, or bypass the UPS and things work fine. The battery was kicking out about 80V when switched on per VO meter. It did handle a 100W light okay. What else could it have been if not the battery? I still have it so I could test it if I new how. |

As to AC power stability from the power utility, I see brief or momentary power outages all the time in my area, I live in a large midwestern US city and see power drops mostly on clear sunny days (iow, not weather related). Oddly, I usually hear what sounds like a very loud gunshot in the distance when power dropouts occur (I live about 1 mile from the power substation). Since I work out of my home, I invested in UPS protection for all critical systems, and some not so critical systems (hehe, my gaming rig). -- Best regards, Kyle |

No.
Capacitors are used for filtering. They would not react as you hypothesize.
