    Default Must read before buying new battery (UPS or Car)



    To prolong battery life and get maximum performance must follow these points.

    1. Never Use battery without initial charging.

    2. Never charge the battery soon after putting the electrolyte in it.

    3. Leave the battery at least 25 to 30 minutes after adding electrolyte than connect
    with charger which gives 10% ampere of battery capacity.

    4. Charge the battery till it reaches 15V and, replace the battery caps, look all cells are
    producing bubbles equally.

    5. Every battery have a manufacturing date printed on it........Purchase latest newly
    manufactured one.

    6. Make sure that before adding the electrolyte, battery was completely sealed and air tight.

    7. Now some companies offering already prepared electrolyte, prefer that one, rather
    then prepared by the electrician or battery vender.

    Any query regarding battery will be honestly entertained up to My knowledge Insha Allah

    This volts of 280 can be reduced to 230 by two ways. The best one is to replace the KIT with the latest one With charging ampere control, output volt control and overload control.

    Secondly you can reduce output volts by shifting inverter wire to lower one.
    Oka brother. Thankyou for your reply.
    Everything is oka. So i think i should leave the way it is operating and not disturb it.

    The setting of your UPS is ok these higher output volts reduced as the load is increased.
    280V No load
    265 with one Fan
    250 with two fan
    240 with three fan
    220 with four fan

    Dear, i was able to solve my previous issue of high charging through your advice, however now i am faced with another problem and I need your help. The problem is that my circuit breaker which is installed behind the UPS will trip automatically. The first instance of this happening was when a bulb got fused. Jaisay he bulb fuse howa, UPS tripped due to tripping of circuit breaker (CB). i tried to turned it on again but the CB's button got free and was not turning on, so i waited for like one minute and turned it up again and UPS started working normally.

    i didnt pay attention to this much, but then today i wanted to test my battery as even if it is fully charged its voltage drops to 11 volts the moment light goes. Even though only 2 x energy savers or turned on UPS. So i wanted to increase some load and see if the voltages drop any further. So i did the following tests:-

    1- i turned on a fan, it didnt affect the bty voltages, however just after 2-3 min after i turned on the fan, the CB again dropped. i again tried turning it on but CB's switch was free and didnt work, after 30 seconds to one minute i turned it on again and it worked and UPS started functioning again.

    2- To test again, i this time turned on two fans, again after a few minutes the CB again tripped, although the bty voltage was alright i.e. 11 volts. i turned on the UPS again by switching the CB after one min and it worked.

    3- Thereafter, i turned on my 29 inch TV on the UPS and it worked fine. The voltage were still 11 volts.

    4- i kept my 29 inch TV on while on UPS, and after 2-3 minutes the CB again tripped. So it means that there is no problem with the bty and i think my CB is faulty. What do you say?

    Remember, it is the same CB which was not even tripping when my UPS was charging the bty at 40-45 amperes. It only had tripped once or twice while charging on this high amperes.
    Dear @Ishtiaq778
    Waiting for your input.
    Thanks

    Brother the wire you marked as 220-230 and 240-250 i use it to increase/reduce battery amps... By now its set on 15 amps..
    And i have adjusted the ups trip timing's to trip when battery is on 13.6 to 13.9 volts.. (After reading your thread..)

    And secondly @Ishtiaq778

    brother what should be the amps of ups to charge a 175Ah battery?? In given situations...

    1:: if its new and first time electrolyte is added..

    2:: if it is 2 to 3 months old battery... ??

    Dear circuit breaker is faulty. Replace it wit good quality CB.
    What is location of cb? Is it on chaging line or ups output line?

    For 175 battery 13 to 15 amp charging is perfect in summer, while in current situation 5 to 7 amp charging is best

    brother how to determine how much amps will be enough for a particular battery ?? any set rule or formula ??

    and secondly, i am checking my battery and trying to set the ups to trip/stop charging once battery is at 14.2 v and checking the battery voltage time to time (after disconecting it from ups) but when i check the battery it says 13.9 and decreases to 13.8 then 13.7 then 13.6 and so on decreasing... is it normal ?? shouldnt the battery hold the charge instead of decreasing it ???

    Charging formula is C10. Means Battery amp/10 so for 175 its 175/10.
    After charging full battery volts decrease till 14.4 - 14.7 volts, its normal.

    So by that you mean i should charge it at 175/10= 17.5 Amps??

    Where as @Ishtiaq778 recommended not to increase more than 15 ever...

    Thankyou for the reply

    This is how the Circuit Breaker (CB) is connected:

    The Black thick wire from battery's negative terminal is connected to the top of the CB. Then the same black wire is connected to the bottom of the CB from where it goes to the two steal plates. I am attaching the pics. So, is it on the charging line or UPS output line?

    Also, is there a different CB for AC and DC currents? Or they are all the same? And kitnay amperes wala CB lagaon UPS per as I would be getting this one replaced.

    Thanx in Advance

    This is AC circuit breaker, not DC. DC CB are not available and AC CB dont work in ups like this. When current passed through this breaker, it heats ups and internally disconnected. There is no use of this breaker , no benefit. I suggest you to remove this breaker and connect the wires directly.

    The assembler of this ups used CB for safety of reverse polarity and any short component like rectifiers and transistors. I have tested many UPS with such CB system but useless. I simply removed the breaker and connect the wires directly. For safety a small fuse circuit can be used.

    Nasirjavaid rightly said, battery charging ampere formula is 10% of Battery ampere capacity.
    GX 175 battery have 130 amperes in it.............175 is merely a number not battery amperes

    There is no set rule to determine actual apms of battery. Every battery brand have different code for same amps of battery.
    for exampl Volta 240 = 160amp ags 200= 170 amps phoenix 220 168amp.
    No of plates per cell is an easy way to determine the battery amperes, not exactly but +- 10 amps difference
