How to extract batteries from an APC Smart UPS 1400

greg milton, Hi, Did you get the top cover off of the "1400" battery back-up? How old were the batteries in the unit? My APC 1250 has two 12v 18ah units inside. It's best to replace batteries every 3 to 5 years! 12fixlouie

Ups does not power up. the power indication light does not light.

Depending upon how old your UPS is, it may need new batteries. To get help, you will have to contact APS or if you have a local Batteries Etc or other battery retail store that can check the unit for you. Without checking the battery condition and running diagnostics, there is not a lot that can be done to give you a better solution.
Hope this helps.
Let me know what you find out. Thanks.

Blinking lights

The problem is, is that while the unit is not overloaded (too much plugged in) either the batteries are close to failure, OR more likely you have so much plugged in you have less than 2 minutes of runtime.

Try removing some devices, lower the load. The row of green lights on the left is your load level indication, you want no more than 4 lit usually, 80% load is the most recommended. This will allow more runtime and should stop the flashing.

The flashing is just ment to alert you to less than two minutes of runtime.

If you have 80% load or less, and it still flashes, press and hold the on/test button until it clicks over to battery, the unit will now run a self test and switch back to main power after a few seconds and it should stop blinking.

The Battery symbol w/ the X thru it had the red light on. I replaced the batteries and the light is still on. Do I need to do something to make the light go off?

you have to press the on button for about 6 seconds to self test the UPS, after the self test the battery replace indicator will goes off, but then much better if you know how to do the APC UPS calibration, from there you can adjust all UPS constant settings.

Unit is switching to battery power for now reason.

Any UPS monitors the incoming AC level to determine if it is needed or not.  I think the APC unit doesn't know any more when it is needed; it's sick.

Apc 1400

Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. There maybe one battery in a set of batteries that is faulty and causes the whole battery system to fail and indicate a battery fault.
The other possibility is the charging circuit may be faulty.

APC Smart-UPS 1400 no power

Better late than never...

The older Smart UPS models are peculiar in the way that they appear dead (will not power on) if the battery is completely bad.

Replace the battery, and the UPS should come back to life.

After powering on, all non-graph LEDs keep blinking

That meens that UPS dont have battery power for minimum time (2min). Unplug some devices so UPS load need to drop below 25% and lets UPS recharge battery
