You don't say which model you have, however it is easy to reverse a set of battery terminals when more than one battery is used. Many of these units use TWO 12 volt gel cells.

Open unit and check all cables AND that no wires are pinched.

Verify the battery voltage for each is correct. The unit will not start if batteries are totally discharged.

New batteries in Smart UPS 700 only lasts 2 minutes at 30% load


If you blistered your older batteries a good chance your inverter is going or will go bad. The heat alone can do damage to your components. Time to replace the unit and remember next time not to wait so long to replace your batteries. Replacement of batteries every three to approaching four years is a good idea.

APC external Backup battery is not working plz


It may just need a new battery. The UPS will do a self test on the battery when you turn it on. It may have tried to read the battery and the result came back as "failed". The batteries last about 3-5 years, even less if you live in an area with bad power. The batteries are very easy to change. You can buy replacements at www.batteryinternational.com/apc-backups-es-be350es-ups-battery-ups-batteries-f1.html

UPS shuts down when the mains is off.


Hi

After 3 years, i would by a new UPS...

The battery will have to be changed if you want to keep the old one.

What i've seen mostly here in south africa. When the battery life has ended they customer opens the ups and takes out the battery and then connects a car battery to the terminals. The then close the ups and let the car battery stand outside the ups.

Hope this info helps...

Ups problem


The batteries need to be replaced. They probably have more than 3 years.
Replace the batteries and let the new ones charge fully for a day and your UPS will work like new after that.
