elektrified Posted September 28, 2012 Share Posted September 28, 2012 It seems I need to buy a new battery for my UPS battery back-up once a year. Is that about right? Of course wherever I take it for service they try and sell me a new unit but I don't see the point, the one I have works great when the battery is good. I always refuse and insist on a new battery. Thanks in advance. Link to comment Share on other sites More sharing options...
Tywais Posted September 28, 2012 Share Posted September 28, 2012 The minimum time I've had to change was 2 years but normally mine have lasted around 4 years. Link to comment Share on other sites More sharing options...
elektrified Posted September 28, 2012 Author Share Posted September 28, 2012 Thanks for that Tywais. I wonder what the problem is? I know I am not overloading the 850VA 400W Supply. Link to comment Share on other sites More sharing options...
flash77 Posted September 28, 2012 Share Posted September 28, 2012 Last battery I changed was a bit over 2 years old (Syndome). Current one still running in office (APC) is at least 2 years old. One year sounds too short unless you are using the battery, instead of mains, on a regular basis. For a replacement battery I went into an electronics shop (NPE at Zeer Rangsit, www.mynpe.com) and they happily found the right size battery, replaced my old one and gave it a quick test. From memory, cost 600 Baht. Link to comment Share on other sites More sharing options...
Gregory Morozov Posted September 28, 2012 Share Posted September 28, 2012 If you have frequent and long power outages then 2 years is normal considering temperature and humidity that also affect the battery life. Link to comment Share on other sites More sharing options...
JSixpack Posted September 28, 2012 Share Posted September 28, 2012 I get about 4 years out of mine. Maybe you need a better brand of UPS. Link to comment Share on other sites More sharing options...
barryw52 Posted September 28, 2012 Share Posted September 28, 2012 I say anywhere between 2 - 4 years this depending on the actual quality of the battery in the ups and it usage. Link to comment Share on other sites More sharing options...
lopburi3 Posted September 28, 2012 Share Posted September 28, 2012 One year indeed sounds very low so I would bite the bullet and buy a new unit if just a normal user system - there may be something wrong with the charging circuit in the one you have now. I have been living without for the last several years as wife did not appreciate the alarm (and after those wires cut) or clicking in the middle of the night. Failures are few enough to not be much of a problem and Windows 7 seems to handle such much better that previous operating systems. Link to comment Share on other sites More sharing options...
WhizBang Posted September 28, 2012 Share Posted September 28, 2012 I would say on average, you should get 3 to 4 years out of a new battery. Certainly to be getting only about one year is too short. Are you sure that your service center is installing NEW batteries, and not something old or refurbished? Link to comment Share on other sites More sharing options...
NHJ Posted September 28, 2012 Share Posted September 28, 2012 Some low grade batteries have defective valves and die very fast because the acid is leaking. Link to comment Share on other sites More sharing options...
Tywais Posted September 28, 2012 Share Posted September 28, 2012 Some low grade batteries have defective valves and die very fast because the acid is leaking. All UPS batteries I've seen are sealed batteries. If the acid is leaking then perhaps they're putting in motorcycle batteries, some which have caps to top up. But then, if acid is leaking the UPS would be toast long ago. Link to comment Share on other sites More sharing options...
astral Posted September 28, 2012 Share Posted September 28, 2012 My electrician advised me that there are two settings on my UPS. APS where the battery is only used when the power fails. The mSec delay switching can upset some equipment. UPS where the battery is being used all the time and constantly being topped up from the mains. No delay when the power fails. The problem with the UPS setting is reduced battery life I run it in APS mode these days. IME the 150AH truck battery may only last one year on UPS mode. Very important to make sure the battery fluid is kept topped up, a check once a month is advised Link to comment Share on other sites More sharing options...

asiawatcher Posted September 28, 2012 Share Posted September 28, 2012 (edited) I have some that have never failed - I pull the power to them on weekends and replug mains to charge again on Mondays. Doing that once a month seems to keep them good - I have had one for 7 years and two others 3 and 5 years now and never a squeak. On iMacs, printers and phone charges they take 15 minutes to crash out when I unplug mains. They are 700 watt or Va, not sure which as I have not looked in a long time.

Do you think the brand of the UPS has an effect on the battery? I checked mine out today and the components are all high-quality brand name; assembled in Thailand. Some I have seen are junk, made in China. Link to comment Share on other sites More sharing options...

Thanks lop, I dropped the unit off at Amorn this evening and specifically asked them to check the charging circuit. Link to comment Share on other sites More sharing options...

Since Amorn supplies the batteries, I don't believe that is the case. Link to comment Share on other sites More sharing options...

That is where I get my batteries too. How is the power in your area? Any unusual problems? Another thought, could you be exceeding the load on the UPS?
