UPS problem

[CA50]

hi friends 2day my UPS gave up
It wasn`t giving backup, so i opened it, and found that the negative terminal of the battery broke into two because of corrosion.
Is there and possiblity of getting its life back?

Oops................

I'll say get a new UPS or Replace it if it's under warranty instead of changing the battery. Look for APC ones. It'll cost u 2.5k approx.

Is any part of the terminal still attached to the battery unit..?

no actually the terminal is now a bit inside da seal. I am thinking of soldering it, hope it wil woke.

Ya..you could. Soldering should work. Sounds like fun work.

yeah fun works, but da soldering area is deep inside da seal

^^
I guess the battery electrolytes are in a deep layer. So you should be able to melt the seal a bit, and get to the contact. Then try to solder. Initially you can try a hot-wire. Just attach a wire (wrap it), and see if the contacts are working. Then try the solder...

Yeah the end contact is visible, i checked with MM, da batt was fine.
Fnds hav u got anyidea how to melt or break da seal

[Krow]

VA means Volt-Ampere IIRC.

[krishnandu.sarkar]

^^ Hehhehhe. He knows what VA means. He's asking about how much VA he shud luk for....!!

Luk for normal 600VA. I'm not so sure.

Well see what other member suggests. As ur UPS battery is f9 u can repair it also as u r thinking off....!!

[Krow]

Damn, I should read entire threads rather than just the last few posts. Almost like watching a movie from after the interval.

1. Are you able to hot-wire the exposed battery contact to the UPS circuit, and check if it is working fine.

2. What you checked with VM -- the continuity of the battery power.

3. You can melt the seal, but taking any hot rod (screw driver heated on fire) and push it in. Or do it with a hot solder (I do that), and immediately wipe the melted plastic off the solder using a cloth.

the terminal is deep, the multimeter probe touched the end contact n i measured the voltage reading, it was 12.03v so batt is alive. And abt da seal i wil try it right away. I wil post its pics, currently i m using cell phone 4 browsing, so hav patience.


@krow, whats offtopic man?

Here is da pic of my ups batt

^^ Melt it like I told you. Use a extremely hot screw driver. Heat it over the gas, and start to probe.

It will get messy, and might render the screw driver useless. If you realize that the electrolytic sealant has been breached, carefully dispose the battery. Its toxic. Do not just put it in the home dust bin.

Do this 'operation' on the floor, on top of some old news papers. So if something leaks, will not cause harm. Do not let the liquid touch your skin. Best of luck. Have fun.

Thanks asigh, i tried breaking off da seal n soldering, no electrolyte got leaked, here is the pics of da batt, hope it wil work,


do u think da batt blow when working?

[asingh]

Hey..that is a good job. It should work.

I would suggest to use it like this:

1. Attach it to the UPS circuit.
2. Let it charge for a while. (Do not hook up the computer)
3. Then discharge the battery by hooking up some low power devices. Say a 100W household bulb, for an hour.
4. Charge it up again. Verify it with the VM.
5. If all fine, hook it back.

Put some tape on the solder. Great job....!
