Here is how a APC original should be .

Back-UPS HI - Product Information
This is the 'BI' and not the 'HI' model.

(BI850SINE is the exact model number)

After going through the site, even I thought they are a fake.

APC site is to blame. It is not in the list but when you search for it comes up. And it seems to be India specific model.

Default Re: Inverter Batteries

I am being offered a battery brand called "Arise". A 160AH tall tubular battery costs RS 9300.00 after discounting the old battery. I have never heard of this brand and upon Googling it appears to be a Delhi based company. Does anyone have an idea as to the reliability of this brand?

^^ I have finally bought a new 1000 VA inverter, Exide EL+ 150 AH tall tubular battery and matching trolley for Rs 21500.00. Got a rebate of Rs 2500.00 for old Amaron battery+600 VA inverter+trolley, so a net price of Rs 19000.00. Battery comes with a 60 month warranty (48 + 12).

This gentleman has assured me that for this combination, I will not have to change the battery before the year 2021!

@Gansan: can you provide cost breakup for battery and inverter. I got tall tubular battery from a company called JC battery around 12K with 48 months warranty.

Vijay

^^ Rs 5000.00 for inverter, Rs 15000 for battery and Rs 1500 for trolley. The inverter brand is "Neltron", manufactured locally by this gentleman himself. He basically makes power back-up systems for industry and has diversified in to home systems too.

I felt the battery may be a little cheaper elsewhere, but this man provides good service - will take care of the battery warranty issues if any, will provide a standby inverter/battery if any of them are taken for service, etc. It will otherwise become very difficult if we have to carry the battery to the dealer in case of any complaint, as it weighs 78 KG!

Default Re: Inverter Batteries

Thats a good price for 1 Kva. For chennai its best to have local brand inverter especially if located in suburbs like pallikaranai where the voltage never raise above 170V and in peak summer you can run U.S appliances without any converter . Based on your earlier post I have made sure charging voltage is set around 8Amps to avoid battery damage. I have installed 850 VA inverter today and tested with 3 fans, 5 tubelight, 1 cfl, 32" lcd tv + set top box and PC (AMD 550BE unlocked proccy + benq G2220HD). It shows over load then I turned off one tubelight and everything went alright. So I hope its really 850 VA and no noise from fan (sine wave). I didnt install trolley and total cost with wiring came around 17.5K . I know from other source Base teminal 150 tall tubular Battery for 11k and microtek sine wave inverter for 4K but I need to take the battery and inverter from there place. Just for 2K it would be herculean task to move these things around the city.

Regards,
Vijay

Default Re: Inverter Batteries

Are you sure about the load you have connected? Because I have been told the safe load is 4 fans + 4 lights and a TV for my inverter. It takes the load easily when tested with an ammeter. He says the output current can go safely up to 40 amps.

What brand is your inverter and how did you set the charging current? I have been told my system will start charging at 9 amps and as the battery charge rises, the charging amps will come down gradually.

Default Re: Inverter Batteries

I just connected maximum load to check for noise from inverter. Its a local made called "zest". I have not checked the charging current as the guy didnt bring clamp meter with him. I need to check this myself. But the charger cut off voltage was set at 14.25V. The inverter resume charging at 13.01V which means the battery takes 5 sec on ~ off cycle between charges once fully charged. I am thinking to reduce this terminal voltage to 13.8V to avoid over charging and less electricity consumption.

Vijay

Normally clamp meters are used for AC and not DC. You either need to have a DC ammeter connected in series with battery (or if you are feeling rich and have resources, a Hall Effect Clamp meter for DC).

For long battery life you have to set the charging current to max 1/10 of the battery capacity, preferably to 1/20. That is for a 150AH battery the current should be between 15 and 7.5A. Once the battery is charged you require "Float Charging", which is battery dependent, but normally 1/100 of the battery capacity, which in this case should not be more than 1.5A.(this is current required to compensate self discharge)

Voltage based regulation will charge the battery at a very high rate initially, and should be avoided. The charging circuit should change over from normal charging to float charge when the cells reach 2.3V, that is 13.8V.

Here is the sticker on top of my new APC-UPS, which advertises your point.

Default Re: Inverter Batteries

I just moved into my new rented apartment and they don't have provision for the inverter setup. The electricians are quoting very high for getting this done as they want to separate out the connections for heavy loads. The main is also 3 phase and the attached bathrooms are with the bedroom connection at the distribution switch (which includes Geyser).

It will be great if someone can help me with any suggestion/diagram of how this can be done in a simple way. As this is rented, I don't want to do something elaborate and expensive as I will be moving into my own flat in a years time.

Thanks in advance.
