Ups repairing

Never throw away your UPS first, maybe your UPS is not dead yet. You might repair it within a few minute. Many computer shops will ask you to buy a new one UPS rather than change the battery, because they want to push their sales only. Don’t be fool by them, you can repair it, without throw away the old one, we need a green world isn’t it ?

Losing Important Data Due to Power Cuts? Buy an APC UPS Today!

The life time for the UPS normally in 1 or 2 years depends how much power failure during these period. Most of the time is battery failure, but not your UPS failure.

Unless your old UPS is burn out or some of the capacitor burn, if your fuse shorted, you just change the fuse.

Make sure your warranty is expired, if the UPS is still under warranty, you can claim and they will change free for you. APC have 2 years warranty, and other brand maybe have 1 year warranty only.

I found that APC is not using own brand battery too, so, don’t think that big company will give you good things inside. But they do provide better service than other.

Most UPS are using 12V 7Ah to 12V 7.2Ah battery, make sure the Ah is not over than that, if you put a 12V 7.8Ah, it won’t be worked.

You should open the UPS and check first which model of battery you should buy.

A new UPS could cost you 1,500 ( 50 USD ) Baht to 3,000 Baht ( 100 USD ), but the cost of a battery 12V 7Ah or 12V 7.2Ah is cost around 450 Baht ( 15 USD ) only. You could buy from most of the electronic shop. If you buy in computer shop, I think they will charge you more than that. If you send to repair, it will take you more time and more cost.

Here is the step to repair.

  1. Check that is Fuse broken or not. ( If broke, just take out and change it, normally is 5A 3A or something )

  2. Open the screw, from the back side and open the cover.

  3. Un-plug the red and black cable that attached to the battery.

  4. Take out the battery and take a photo ( with your phone ? ) or mark down the value ( because maybe you don’t understand what they wrote on the battery. )

  5. Bring your UPS battery photo or note to electric shop to buy one.

  6. Put the new battery to the same location in the UPS.

  7. Plug in the black and red cable to the battery.

  8. Close the cover

  9. Power on

Most of the case the UPS will work again. If it is no work anymore, then you can send your UPS to recycle. :)

If you just throw away or you just put them in the store room, you are making another piece of rubbish to this green world.

How Do You Test UPS Battery?

Okay, how do you test UPS battery? UPS stand for Uninterruptible Power Supply and this equipment use the seal lead acid battery type. If you check the voltage of the battery with a normal multimeter, then i guess it is not accurate because a bad battery may also show a good voltage. The battery will fail under load test! If you really need to accurately test the battery you need a battery tester that is design to test such battery like the one in the photo. For a good battery the pointer will kick up and stay there and you could feel the heat underneath the meter (perhaps there are big resistors to act as a load). You can’t test it for long as it can become very hot. At least with this test you are now know that the battery is good.

If the battery is weak (but multimeter showing good voltage) the pointer will flick and then gradually coming down. In fact this type of meter is design to test on the automobile battery and can be used to check on seal lead acid battery too. Do you have other way to accurately test a seal lead acid battery? Appreciate your comment-thanks

 

How to Test UPS Batteries

UPS, or uninterruptible power supply, battery backups provide users with power in the event of an AC power outage, but if their batteries are not properly charged and functional, you can lose your work. You must ensure the UPS batteries are working properly, so this does not happen at the worst possible moment. By following a few simple steps, you can verify that your USP backup's batteries are working as they should.

 

Instructions

    • 1

      Plug the UPS backup power supply into an open AC outlet, then power it on. If your unit's power light does not illuminate, try a different outlet to eliminate that as a possible problem.

    • 2

      Allow the backup's batteries to charge fully, as specified in the owner's manual. The amount of time this takes varies, depending on the make, model and size of your UPS backup power supply.

    • 3

      Reset the UPS backup's circuit breaker by pressing the "Reset" button located on the back of the unit. This button is usually located on the back of the device, next to the phone line, USB port and other connections.

    • 4

      Plug the monitor into one of the "Surge Protector Plus Battery Backup" outlets on the back of the device, then power it on. Most UPS backups offer both traditional surge protection outlets and those with battery backup capabilities as well.

    • 5

      Unplug the UPS battery backup from the AC outlet. If the monitor powers down, the batteries are not keeping a charge as they should; if it remains on, they are functional.


How to Test an Exponent Battery

 Modern batteries, such as those used in electronic devices or cellular phones, use an exponent-based system to measure battery capacity in ampere-hours. For example, if you test your battery in amps and it produces a reading of 50, that means the battery produces up to 50 amps an hour. The best and quickest way to test your battery to find out how many amps it has is with a voltmeter.



Instructions

    • 1

      Turn on your multimeter and set the reading to "Amps" using the dial on the front of the meter.

    • 2

      Insert the colored test leads into the ports below the dial. The red lead goes into the port marked "+" and the black lead goes into the port marked "-".

    • 3

      Touch the red lead to the "+" terminal on the battery and touch the black lead to the "-" terminal on the battery in order to ground it.

    • 4

      Determine the amps after waiting for the meter to produce a reading. The reading will display on the screen on the front of the unit. However many amps the meter displays is how many amps the battery uses per hour.
