Assalam-U-Alaikum, I searched in Google and found you website. I am hoping that you'll help me in what I want to ask. I have a UPS(Inverter) of 600 Watt from which I am running 4 fans (60 Watt each) and 10 energy saver bulbs (13Watt each). 2 Lead Acid batteries (used in cars) of 12volts 60Amp and 65Amp each are connected in parallel. After 3 months the UPS kept on charging batteries and 1 of the batteries (65Amp) got very heat up. So when checked one of the batteries (65Amp) got dead i.e. one of it's 6 cells got dry. Can anyone tell me what is the reason that this battery got dead while the other one is still working fine even after 1 year.
Now I want to buy 1 big battery (used in buses) so that it'll be easier for me to do maintenance in which after every month I've to put water in it. There are many brands available in our market (Pakistan (country)) i.e. Volta, Osaka, AGS, FB, Exide, some shopkeepers say Volta is good some say Exide is good, some people say FB or AGS is good, so I don't know which 1 to buy. Can you please also tell me whether I should buy 150Amp Lead Acid battery for my 600Watts UPS or 200Amp battery for the same UPS (Actually inverter). In our country 220Volts are used just as in UK and not 110 Volts.
Someone told me that he is using Volta battery and he puts water in it after every 2 or 3 days. But I used to put water in my Exide batteries after a month and someone else I know used to put water in his AGS battery after 3 months.
Please tell me how can I decide that which lead acid battery is good. Prices of all are almost same. Excid is old.
Can you please also tell me from where can I get you newly launched maintenance free battery and what is the cost of that battery and is it really Lead Acid battery.
I’ll be very thankful for the reply.
