APC CS 350 Overload light is on. I replace battery with the new one, but the problem still exist - charging no more than 10%. How can I fix it? Thanks

This sounds like a battery issue, test the battery by itself....

light overload is lithing on apc-ups

Try unplugging some equipment from the UPS. The total load should be less than 865 W. Printers and scanners often are culprits.Some gaming desktop computers can have a power supply that will be too much for this UPS. (I've found that even having the printer on the surge only part of the UPS can be a problem. I have the printer on a separate surge protector.)

Since the overload is new, did you add any equipment to the UPS recently or upgrade components?

If you reduce the load, and the problem continues, the UPS may have a fault in the circuitry. If it is under warranty, contact APC.

I hope this helps.

(I have replaced APC units after 3+ years when they can't properly recharge the battery - with a new battery. The symptoms are 1) getting a overload when a small load is on the UPS. Small load - desk lamp, 13" TV or 2) not keeping the item on when the power goes off.)

Hi,
Definitely you have replaced a new battery, but my dear friend every battery need to be charged by electricity before using it. Connect the UPS for at least 10-12 hours with power & do not switch your UPS ON while charging.
Good luck...don't forget to rate the solution

Check all MOSFET.

How old is unit? UPS is a Battery that is charged from power outlet.It maintains voltage when computers are plug into it so fluctuations in current don't spike or wane.On a Power Failure the UPS supplies all the power by using the battery and an inverter.If your units batteries are not charging you need to replace them.In most cases it is not cost effective.Do some more test before you replace it.Good Luck.

well u cant do anythng to off the alarm becoz the unit is having a problem hardware issures... juz off the ups..ask the vendor to come and check..

Try looking for a small circuit breaker on the side that says "press to reset" - you could have tripped it accidentally when you unplugged the iPod.  Also, try pressing and holding the UPS power switch for 10-15 seconds.  That should force a power on as well.

My solution was to unplug everything, hit the reset button, and then power the unit back up. The problem I found to be that I had my laser printer connected to the "surge + battery" side, and for some reason no laser printer can be connected to it.
