A few questions. Is it an stand alone one? seems to me a 500VA rated UPS, for light loads only.

Some stand alone common problem.

1. Battery for replacement
2. Fuse busted
3. Faulty relay

If repair and battery replacement outweighs the new one or got a small difference. Its better to have a new UPS unit.

Hope this helps

Hi Lasantha,

Check the battery in your UPS - it's most likely going bad and you will need to replace it.

How much will a tuneup for a 2004 buick La Sabra


Generally speaking, modern cars do not require "tune-ups" like older cars. There are regular maintenance tasks and wearable components that need to be replaced, but the costs vary wildly depending on the shop and the brand of parts they use. Oil change, air and fuel filters, and, every 10k miles or so, spark plugs and wires are about all that needs done unless indicated. Also, coolant change, which I do annually on all cars I own.

ups with 300 watts can only back up 1 computer, though it can handle 2 computers but not too long. your ups battery life span are good only for 2 to 3 years. for battery replacement you can visit the nearest service center and ask for battery replacement. it will not cost you much.

On our 20kVa unit we got a 'battery must be checked" alarm. We replaced the battery but alarm still on unit. How can we get rid of this? We already did the normal reset but alarm still there. Thank...


The internal automatic battery test is picking up some differences between the actual value of the battery to the mathematical calculation used in the software. Normally if you do a battery impedance test you would find that the batteries would be consistent and therefore replacing the batteries may not be the solution. Once you transfer the UPS on BYPASS and then recycle the power you would clear the alarm. However on the next internal automatic battery you would be getting the same alarm again.

At times this may be a software issue or an SNMP problem. Normally to refresh the battery data for the UPS monitoring software we carry out a battery discharge test. Please consult with the supplier if an annually battery discharge test is mandatory for the battery monitoring circuit to work well. Please let me know of the outcome
