The voltage reading must be taken during fully charged state without load.
Also check the voltage when its boost charging and when it enters into float voltage.

Exide batteries used in inverter have conked off, after serving for about 6 years. Su-Kam guy is recommending Apollo batteries costing 11k each (2 years warranty), Exide ones cost 13k each (3 years warranty).

Any other choices and recommendations? My UPS rating is 1.4 kVA.

What is the AH rating on the old batteries?

My suggestion is to buy Exide.

However, there seems to a huge margin on Exide battery cost (approx 1-1.2K), so do shop around to see if you can get one for a lesser price. I bought Exide invared 450+ for 10K MRP from a dealer while others were selling it for as high as 12K.

I bought Amaron batteries (AAm-CR-I1500D04R, 150 Ah, cost 9,700/- each) from batterybhai.com. They were not delivering Exide in Thane.

I booked in the morning after speaking to call center. I was told that the batteries will be delivered in about 4 hours. Nobody called even by 3 pm. I called them up again and the local supplier called after sometime. He had an excuse, we don't have the necessary batteries in stock. On insisting that we want the batteries to be delivered today, they came at 8 pm and completed their job in about half an hour.

I brought Exide inva Red 450+ from R.K traders, Bangalore. It cost me 11k after giving my Pristolite.

There seems to be some discrepancy here. There is 3K price difference. I bought mine for 8K after old battery exchange (Dead exide battery). The least you could get for an old battery is about 700-800Rs.Even If you consider a regional price difference of about 800-1000Rs., there seems to be a lot of price difference. Inquire with other dealers to know the baseline price in your area.

MRP on the Exide invared 450+ is Rs.12,xxx for all cities except Maharashtra (on box),

Hi, I need to replace my Exide Inverter Plus 500 battery attached to a luminous 800Va inverter. I have shortlisted Exide InvaRed 500 . I cannot go for the tall tubular batteries due to space constraints. Is this the best option? I prefer only exide batteries.

Also is battery bhai a reliable portal to buy the battery?

Just got new Exide InvaTubular IT 500 batteries for both home and office inverters as both needed replacement. Price quoted by dealer was 14500 per battery and he bought back the old batteries for 2k each. Checked out batterybhai website and found the prices on d higher side.

Did you find a suitable alternative to APC?
I also use the SUA750I.
Have been searching for a cheaper yet pure sine-wave & reliable UPS alternative but haven't found any!

2 years before, I bought 150Ah tall tubular battery (JC battery) for 11K I remember. It gave exceptional backup time > 24 hrs with judicial use of power (1200W). Off late whenever the battery is over loaded with around 700Watts, I am getting weird smell. Later I found its from the negative terminal post and the temp is more than 90C. Replaced the cheap 10sq.mm ups wire to Orbit 15sq.mm wire. There is no burning smell or wire heating, but I am noticing drastic drop in battery backup. We had a electrical cable burn that cause 1.5 days of power outage. This time ups gave max 12 hr back up which is close to 900 watts of power. I believe the plates re sulfated due to constant deep discharge and charging. I can say its still a better quality compared to other brands.

Can someone help me understand how I'd go about filling distilled water in this battery, please?

It's an Amaron battery with Amara Raja inverter. I'm unable to understand what to disconnect or power off before filling up distilled water:

Hi, its a fairly simple procedure and you don't need to disconnect anything. Just turn the mains supply off and put the inverter switch to off position. Fill all the cells after removing their respective caps with distilled water and make sure that the level remains between max and min. Take care not to spill water anywhere as it may leave stains and also take care not to have contact with skin also. After filling, close all the caps and wipe any extra water spiled on battery and after you are done turn on inverter and mains supply.

Thank you for the super quick response! With your encouragement, my dad and I just got to filling it and it was a no-nonsense affair. The hardest part was lifting the heavy battery out of the enclosure.

We tried to stick to the level between min and max but on a couple of cells it did slightly exceed the max "green" level. I hope that isn't an issue.

Thanks again, we just saved Rs200+ that they charge to fill it up.
