Now he uses a SWASTIK brand SINE WAVE inverter (900VA) with a local made (ESCORT) battery 180AH and results are quite good. Good thing is charging current is configurable, 6 Amps and 8 Amps. He has kept it at 6 Amps. Takes more time to charge but its good for life of battery.

The new APC UPS has a selectable charging current switch.

My inverter at home finally gave up a few days ago after a long service life of over 15 years! Yes, 15 years! The model was a 1kVA unit from Gravity India and was bought sometime in 1999 and served us well. I changed batteries just once back in 2009.

I called my friendly neighbourhood battery dealer and he opened the unit and said he'll try and source a circuit board for it and looked all over SP Road in B'lore but to no avail since this was a very old model and so advised me to buy a new unit. I've been associated with this guy and have bought batteries for my old Santro, my current Alto and also replaced my old inverter's batteries when they failed in 2009 with a local brand that he suggested and have never had any quality issues with him. His service was also always prompt and he's always been a phone call away.

He suggested that I go for a 1.6 kVA Microtek UPSSEBz1600 Pure Sine Wave inverter since our house is fairly large and has a lot of power requirements in the event of a failure. I mentioned about the negative reviews and some QA issues with Microtek and he assured me that none of the customers he had supplied this brand to had any problems over the past several years. I know it was a small leap of faith for me but I decided to go ahead and buy it since I've had no issues with any product I have bought from him over the past many years.

He offered to buy the old inverter and after the exchange I paid him 7k, which to me, is a good deal. Perhaps, I would have got it cheaper on an eBay or another online store, but it was this guy's service and quality over the years that made me seal the deal with him.

The new unit has been connected to the old set of 2x120AH batteries supplied by the same guy in 2009 which are almost five years old (purchased in November 2009) and has been up and running for a while now. The old unit was a square wave and its nice to have no humming noise when the fans are running now which I had gotten used to over the past many years.

Again, a big thanks to this forum and this thread for the feedback and research.

Guys my Exide Invatubular IT 500 made a sad demise after donkeys years, so need to replace it with the same or any newer generation/facelift of the same. Does anybody know whats the current OTR price of the same.

So exactly how many years did it last?
(since I too own one)

I dont remember when I had bought it. 5 years min. May be more.

Just sharing my experience with Amaron Current (Non Tubular) 140 A for our Microteck 850 VA Inverter.

Our 1st one purchased on 8/4/10. We had to buy another one on 6/5/12 of same type as one cell conked off due to less water (our mistake).

Now this second one has started getting hot like a pressure cooker from last month.

First thought Inverter issue so spend a lot of money on repairing Inverter, while the local repair guys did nothing inside it.
Last call made to Microteck Service man, and as per him Inverter is in perfect condition, its the battery (again).

Battery gets charged till 12.5 - 12.9 V, then after that it just takes in current, but does not achieves the desired 13.8 V for cut off from Inverter.

So the pressure cooker situation.

Now Amaron service came in the picture, very prompt, home visit, free.
Dropped the battery to pit stop.
Today collected the battery, and was told, same, they cannot do anything,
Also battery is out of warranty and worth only Rs 1000, (only lasted 2 years and few months)
Saw also few more of same type with similar situation there.

May be Okaya this time, no more Amaron for Inverter for sure.

Thank you for sharing. Just trying to understand the whole deal but does the statement below not point towards an issue with the charger? I can understand one battery going bad but two in a row is a bit much. Maybe Amaron batteries are too sensitive and the service you get from another brand's product on the same inverter will clear it up. Hope your future update say in a couple of years will be positive.

Exide Inva Tubular, if possible. It has been going strong on useless 48 months warranty, that got over an year ago & still good.

Thanks Khoj,

Well the Inverter gives 10 V first I think this is the peak. All Inverter do same for similar capacity.
Also Amaron does not specify the same as what is best for battery. BTW they do specify as Amaron Current for Inverter use.

If any is in the market for a Inverter setup, the standard is Inverter of this much VA and a battery of this much Amperage, this is standard across India.

Second step is square wave or sine wave.

Still, and now an addition is Pulse charging etc.

It is not that the my second battery has gone bad, yes it will hold charge, and give back up, even for 3 hours it is intended to do, but the battery has to be manually disconnected and connected in the system for use.

Why because the battery will keep drinking power from Inverter, but will not tell to the inverter to please stop and go on stand by, why because it can not achieve and hold the required 13.8 V for stand by to come in force.

Why the battery is doing it now and not before, as it is aging, or getting off warranty.

Thanks Aargee, I am only taking half of your suggestion which is Yes Tubular battery this time, as am over cautious with these Automobile battery suppliers(Amaron/Exide) and was thinking to go with Okaya/ Mtek Power as
the battery has Microteck written right over it, also I think it is the same companies.

[inder]

Aargee, even I would suggest Exide Invatubular IT500. Very competent battery just replaced my 6 year old IT500 with another IT500 for 12500 (includes old battery buyback). The dealer was suggesting CT500 for 11k. But I did not want to try a new model.

Sir, I only stated my experience, no humble opinions and yes, feel free to make your own choice

Personally I would like to try Amaron's tubular, just for their brand name. Also my neighbor has 2 X Amaron's tubular 150 mA, but he's been using it only for 2 years. Anyway, that's me & 4 years ago Amaron didn't have tubular or one for inverter.

Superb. So I got one more year to go huh I would like to try Amaron Tubular next

First of all, Hats off for getting it right on battery the first time itself. I was never aware of Exide Inva Tubular before, an especially the IT500, which is a hot selling product, thank you, seriously.

Aargee From the horses mouth, Yes Amaron Inverter batteries are very dependably, but the star catch is 'only within the warranty period'.

We also went for the brand both times.

Btw I had replaced my car Amaron Flo/go (same, lasted little over warranty) with Amaron black just few months back, and only wanted Amaron, but no more.

[inder]

Guys the IT 500 which I recently purchased has started boiling on connecting to inverter. I talked to the dealer,he has agreed to replace. The local electrician says the inverter is overcharging. Problem is the setup is in my village 120km away. Dont know if the inverter is at fault or the new battery. plz advice.

[ritz3645]

Hi everyone,

In continuation of my previous post, an update as of today,

Took my Inverter battery Amaron flat plate 140mA to Another Battery dealer, and was confirmed on arrival that the battery is dead. Once wired there was no spark, just dead.

Got a mouth watering deal on a 150 TT by Emark battery in exchange for just Rs 5500/. It has the standard 2 year exchange warranty plus the one year pro rata.
http://www.emarkbattery.com/Products1.htm

I was not the decision maker. And in my hunt also found a repairable 200mA C10 TT but made of 4mm plate, from a near by city.
I would have preferred this repairable TT for 6.8K with exchange and scope for negotiation.

FYI some other battery manufactures having TT products for Inverters, they make sealed, not repairable ones.

Also my experience is a 'Flat plate battery and an Inverter are not made for each other', may be Tall Tubular and a Inverter is, hope so.

I couldn't figure out the difference between Sukam Shiny and Falcon. From the Sukam site its clearly does not mention if Shiny is PURE sine wave it just says Sine wave. Falcon is mentioned as pure sine wave. I want to run my 40" LED TV and couple of computers at home. So I need something which is pure sine wave.

But all the sellers put Shiny as Pure sine wave. I checked many sellers online and offline.

Could anyone throw some 'light' on this ?
