Maintaining UPS/car batteries

[dav111]

The original post is incorrect.

1: Washing out the battery will wash out the stuff between the cells too. That means, no more battery for you.

2: OP told me to charge it fully and and then clean it. I asked him again and again and he said "It's safe". It is not. You do get a shock from it though not deadly as voltage is only 12.

I took my battery to my father's good friend's battery shop. They turned it over and that is it. Then they told me the point 1 when I asked them to clean it properly.

... and point 2 happened too while he was closing the caps. A good shock moved him. Battery was half charged at most.

Now I will be getting it back tomorrow. New solution was poured in and charging takes time so tomorrow it is.

getting as shock from it is impossible unless you use your tongue,i have also fused three batteries never got shock

Bought new AGS battery 60 amp.Using it with 12v dc motor fan. first two days it worked fine. now charger shows, its full but "magic eye" colour is not changing and fan slows down after half hour :S.

Come to Lahore and I will take you the person who was on the receiving end.

Well its possible to get a shock with bare hands...but only if you complete the circuit like touch positive and negative terminals by mistake or your clothes are loose & wet and touching these terminals. Other than that, sorry bro it isn't possible, cannot bend the laws of physics for you

What part of flushing and cleaning did you not get?.

Of curse the element 'wet' was present.

bro i have been shocked by various current voltage currently i remember is 920volt ac, 90volt from hid ballaster,220 from main switch but i have haven't received any shock from batteries ranging from 1.5 to 36 volt. that guy would have wet hands that lower the resistance of its skin so he got the shock.
The thing that determines whether you get an electric shock is the voltage. whether the source is AC or DC is not determinant. Car batteries are usually 12v, which is not sufficient to drive a current through your skin if your skin is not wet. The voltage of Mains electricity at 110 or 220 volts on the other hand is easily high enough to give you a jolt. The fact that AC voltages are conventionally stated as RMS (a kind of average) means that the actual peak voltage will be higher still.

Usually, no, but under certain conditions yes. It depends on skin resistance. Normally about 50 volts is considered the upper safe limit however if your skin is less dry than normal that limit may be lower. On a hot day, leaning against the fender of your car, you can get a good tingle from only 12 volts DC. DC is much safer than AC however, since chemical changes increase skin resistance quickly, limiting current flow with DC but not AC where chemical changes are reversed with every half cycle.

AC current is friendly as compared to DC which is most dangerous. I got 470v shock from a digital cam capacitor.my left arm got numb, severe pain in hand , thumb became black

You are wrong. DC is not safer than AC. Ask your money back from whichever teacher you learned this from.

You are completely oblivious of what I am trying to explain to you. If the shock he got happened due to the reasons I told then OP is not at fault, your battery guy needs some training in workmanship.

i didn't said dc current is safer then ac my point is that low voltage like 12volt is still safer it can whether be ac or dc current.btw dc current is more dangerous than ac because dc current flow is smooth when it pass from your body then your muscles contract and you cant move you r hand from conductor whereas ac current is series of wave it give s the time to muscle in which they can react and you can move your hand s from conductor but again it depends on voltage

[talhawaleed]

DC and AC have only one difference and that is Direct current travels in one direction whereas Alternating current switches directions multiple times in a second. E.g 120 volts AC is more safer then 120 Volts DC in terms of electric shock because 120 Volts AC will pass through its zero point which will be a minimal time to get away from the contact point whereas in 120 Volts DC would remain at 120 Volts level and it would be difficult to escape from contact point.

I am still trying to understand, how did your battery guy managed to get a shock. Minimum 48 Volts are needed to electric current to penetrate through human skin. Resistance of skin may lower depending upon if your body is wet or dry. Did he had an burnt skin already or his hands had an injury. Did he shorted both the terminals using screw driver or was he not wearing his shoes.

Anyway, I don’t think he was qualified for this job. Flush does works as all your are trying to get rid of loose material in your battery not active lead. And you have to determine the condition of battery before performing flush and battery should be fully charged.

Dear All, Have any of you heard about a device "DELTA PULSER"? As per my information it is used to 'desulfate' the battery plates when charging and discharging cause sulfation on the plates and sulfation causes poor battery performance. The device has two wires (+ & -) which are connected to the same terminals of battery. A LED is turned ON Green when battery is under desulfation process. A battery of 175 amps needs 3 days to completely desulfate.

sorry have no experience with "Delta pulser" share your comments if you are using it or intend to use it.

[waqar19]

can anyone tell differences between these two pics of battery cell/plates.

[waqar19]

Magic eye. A cool feature from Atlas Batteries. It tells whether your battery need charging or not.
it shows blue when fully charged.


and white when need charging

Well, it takes repeated cycles of charging and discharging for gravity to increases. If color shows battery is discharged whereas it has achieved 14 volts on its terminals then there is nothing to be worried about as with time acid will mix with distilled water uniformly and you would be able to see the right results. Checking gravity is one of the many parameters which needs checking once you are diagnosing an issue with a battery. Secondly, I don’t think so that color of the plates as visible from caps tells you anything about the battery, what I can infer from visual looks is that one may be old and other maybe new. Maybe someone with better experience and knowledge maybe able to shed some light on it.

I have heard that Original battery plates are White and Fake battery plates (made in Jhang) are yellowish. Don't know how much true it is.

I have installed the DELTA PULSER to my ups battery. The ups is homeage old version having 3 LEDs only.

My VOLTA IT-1000 battery was very weak. i mean it would run a ceiling fan and a liquid mosquito repellant heater for just 50 minutes. i will check the timings after a whole week of desulfation... lets see what comes out of it...!!!

maybe, if you could have tried flush first and put it onto Delta Pluser later.
