Battery Charge

[rameez]

Guys,

My car was under repair for about 3 weeks and today i went to collect on the way to work, the car started fine and i went to work in the morning. I also came home in the night with lights on and the setup also on. There was no issue and i parked at my house. But later since i had to reverse it after dinner to make room for my sister's car i tried to start it but it does not start. Only the starter motor trying to turn the engine. It does not turn the engine.

My car a lancer station wagon and the battery is sealed type with 10 months life on it. do you think the battery was dead....pls help.

sounds like a battery or alternator issue. If you have jumper cables, see if you can jump start the car from your sisters car battery. other wise you can swap the batteries and see. I assume both are petrol cars. If you can start the car that way, find a volt meter, turn on you a/c. head lights etc and quickly check the voltage coming from the alternator is within range (14v ~ 14.5v) if its below that it could be an alternator issue. It also could be a simple case like loose terminals. Try searching the forum, this issue has been discussed before.

Rekless too had given good advice. When did you overhaul your self starter motor last. can be some problem in the self starter motor, if the engine starts with a jump start then it can be two things one is battery is not holding the charge or alternator is not giving enough charge with your night load.

Get your battery load test from the person you bought same.

reckless,

my question is how come did the car start fine in the garage it self ,, if at all it should have given the problem then itself.

[Reckless]

probably the garage guys didnt start the car at all, so the battery could have hold a charge for you to run for a day. when you switched on the headlights A/C etc the remaining juice in the battery got drained, and because of the alternator problem the battery never got charged. It could very much be an alternator issue. probably loose connections etc due to garage peoples handy work. Better get the alternator and battery checked out by a good electrician.

[harshansenadhir]

There is an issue with charging. Battery holds power without any issue as it had enough power to start the car after it kept unused for longer period of time.

This usually happens if the charging mechanism equipped with conventional electrical regulator (cut-out in local term) rather than the electronic circuit based in-built regulation. (charging IC in local term) . When the system is not being used for a long time, the coils in the conventional regulator does not get magnetised the way it used to be. Therefore, a correction / adjustment is required.

if your car equipped with (I assume it should) a conventional regulator (cut-out) get it adjusted by an electrician or replace.

Do following before you take it on with the regulator and I do assume you have done these basic checks.

1. Check whether the belts are loosen. If mechanics have messed with an engine repair, chances are high that the belts were not tigten properly.

2. check for any oxidization in either battery terminals or (+) supply from battery to alternator. Check at the alternator end as well.

3. check all grounding contact points for rust and possible contact issues. That too can contribute towards poor charging.

Keep us posted, good luck.

Rameez,

For what kind of a repair you kept your car 3 weeks @ garage ?

I'm sure if you have not gone for a electric repair your battery and the alternator was working fine when you go to the garage.

now after 3weeks you found a electric issue .

If you have not found the correct garage with a good bass fellow this kind of things always happen when you keep the car for a long period @ garage. it always come out with a another issue you have to go to the garage again.

I had enough of bad experience.

the repair was not for electrical issues and it was for tinkering with regard to the under body. I kept the car because there was a some light cover that had to be sourced from panchikawatte. So most likely the car would have been not started for about 3 weeks. so you think that this was the issue.? but i admit i am still puzzled.

I think the best you can do is go to a battery shop and check the battery.

they will check the alternate current also weather its enough to charge the bat while on head light and AC.

then if there's a issue you can go to the electric bas.

dear all,

well i removed the battery and got it charged by our solar charger at home for about 8 hours. The car is now fine. I did not go to work in car for about one day. Came home and fixed it and the car started in one go.. I guess the problem was there was no much charge in the system after coming with the lights on.

However i am still baffled that the battery is down in just 3 weeks. I remember that as a kid there was a lady who used to start her car once a month ( B11) since her husband was abroad and there was no issue.Is there a rough time period for a battery to pack up.......

Go to a auto electrician get your battery connected to a ampere meter run the car on the road with all your lights and other equipment on get the reading of the meter at what speed on top gear your alternator is compensating the battery discharge.

This problem is there most of the cars when you drive with all equipment on on top gear slow alternator do not give sufficient current to charge the battery due to low RPM of the engine.

Then alternator too rotates at low RPM. Moment you change the gear to a low one then the engine and alternator RPM also increases there by full current load is compensated by the alternator so that battery will not run down.

This is one reason I always advice motorists to have a small battery charger in their homes so that you plug on the battery charger in the night battery will be in good condition for next morning start. Small battery charger costs under rupees 1000.00.

sylvi where can i get one ???..............i asked robert agencies they told me it is 21000 LKR but to be frank it cannot be so expensive

Rameez,

Go to Pettah 1 cross street any electric shop will sell 230 volts 12 volts transformer 1 Unit full Wave bridge (rectifier) 50 Volts DC one Capacitor 1000 UF 50 volts DC few yards of wire three pin plug and battery clips. get a old computer power supply fix them all inside you will have a battery charger if you want you can fix a small amp meter. All above is less than 1000.00 Rupees. Or you can mount an a wooden 6x6 1 inch wooden block.

if you find difficult to wire same please contact me I will do it free of charge.

Dear Sylvi how can we know the battery is charged how long will it take if any risk for over charge issues and could you send me the elctric diagram my mail add [email protected]

thanks i also looking this kind of item and cant we use old phone charger pls send me all necesasary spec.

thanks

[Dhanushkapg]

Dear Sylvi,

I also face to those battery issues frequently.Please let me know What are the equipments and how those are connect to make Home battery charger plz. Because it will be more important to me,

There's a ssimple answer to your problem. Who ever was working on your car, took out the battery to perform jump starts on other vehicles. Happens at every garage.

1. The circuit was meant to be powered by a power supply, which is why there is no transformer, rectifier, or filter capacitors on the schematic. There is no reason why you cannot add these.
   
2. A heatsink will be needed for U1.
   
3. To use the circuit, hook it up to a power supply/plug it in. Then, connect the battery to be charged to the output terminals. All you have to do now is push S1 (the "Start" switch), and wait for the circuit to finish.
   
4. If you want to use the charger without having to provide an external power supply, use the following circuit.

Mr.'hatharasinghe',

I forget to answer to your question about over charging normally in 6 hours battery will charge fully because the charger will give only few amps less than three. When the voltage increases on the battery charging rate of 3 amperes also will drop.

If you want to check the battery is fully charged then you have to check the SG of acid with a hydrometer. if you connect a volt meter also will show above 12.8 volts.

Old telephone charger also is good enough for a new batter to keep in trim condition You have to get a CDMA 12 volts DC phone charger which rated at 1 Ampere. Present day CDMA Charges are only 500 Mili Amperes. that is also good but it may take very long time to charge.

The web circuit says it is 3 amperes I have not tried the circuit of that 15 volts ac step down transformer.

Battery charges I have build was Transformers what are available with is 5 amps 12 volts. some times you will be able to get little bigger transformer or smaller ones also there are plenty of Chinese stuff they are quite good.

If you have any more questions please post. I will try to help the best way I can.

Thanks Dear Sylvi I try to make it and i want to know I have UPS (Use to PC) and now its battery dead cant i use that to this as two terminals connect to battery.

Mr.'hatharasinghe',

if you have a ups then take the two wires out which connects to the ups battery connect same to your car battery. then switch on the ups charger it will charge your car battery.

In this way once when the battery got charged that battery current comes to UPS (or computer power supply) and damage or burn the power unit ????

once i tried to charge a car battery from 12V 5A power pack and after few min i got the burning smell and when check transformer have burned out.

The UPS thing as crazy as it may sounds will actually work but i would advice getting a plug in charger as the better option.

This is a totally different matter than the UPS technique, the thing is to charge a 12V battery you need to give more than 12V. When you hook up a 12V power pack to a 12v battery nothing will happen, the current will circulate in the outer circuit and will only heat up the transformer.

Think of it this way; if you have a room with one guy who is trying to get out by pushing the door out and another guy trying to push the door in with the same amount of force to get in nothing will happen right ? i.e only if you use a higher force will you be able to get into the room. Same goes for batteries, if you want to charge a 12V battery you have to give it more than 12V

Guys this is something i found sometime ago and i built it myself so it works perfectly. unfortunately someone "borrowed" it and is no longer with me, im gonna build a new one and ill fill in on the details ASAP

This is an automatic car battery charger with an indicator lamp to indicate when the battery is fully charged and it will automatically cut off the power to the battery as well so no harm keeping it plugged in for a while. But i would advice you to remove it once the battery is fully charged cause no point in stressing the triac and the transformer unnecessarily. And not for the faint of heart

Here is the original site i found it from, has the parts index (http://www.aaroncake.net/circuits/charger2.asp?showcomments=all)

I build this on a veroboard but you can take a printout of this and take it to Ravi PCB in Maradana and they will make a printed circuit board for you. All of the components can be bought locally ( i got them from Senith YBMA borella), some parts that might be missing such as th TRIAC and the SCR; if thats the case try to find a similar component.
