Thanks. Its NOT a "Car battery". It is a home inverter battery. (Just to avoid any confusion).

Home inverter battery setup was connected to mains supply as normal, & there was no power cut at all over the last 10++ days. I randomly thought of checking the voltage on battery terminals, and surprisingly it turned out to be very high - 18.5 Volts. I took it multiple times to be sure, & using...

Did another experiment over 2 nights (10 PM to 10 AM). During these 12 hrs on BOTH nights, 2 ceiling fans, 2 mosquito repellents, 1 fridge, & 1 water purifier was ON. Only the 2 celing fans were on inverter connection, while other appliances were only on mains power supply. There were NO...

My experience with Wipro & Zebronics has been dismal (as stated here - https://techenclave.com/threads/home-inverter-consuming-too-much-power.225132/post-2584569) Better to try this one if rating is good.

Please do report your findings about power consumption. If that small battery (video) is 80w/hr, its like more than a ceiling fan running 24*7*365 non-stop. :confused: A big-big cost for the convenience of the inverter.

Question - This video claims that a normal running inverter keeps consuming power and delivers only one-third of what it consumes. Is it true?

Thanks @6pack. Tech specs suggest that PC does not draw more than 200 PSU (~180 W) - its Lenovo ThinkCenter m700 desktop. More importantly, the same desktop PC is running on the same inverter battery setup for the last 4 years (with same 4-yr old PC config), but the high consumption problem by...

Thanks @6pack. However, I've bought two such 16A smart plugs in the past - one of Zebronics & another of Wipro. First one burnt off on 2nd day when used on a geyser connection. Second stopped working on its own after 4 months. They're costly, so can't keep on buying new :-((

Thanks again @karanwk. These are useful insights. Allow me some time to check these and I'll update ASAP.

@karanwk - thanks for the response. Recently, have charged the battery fully. Then turned off main supply to observe how long it works with 2 fans, Desktop PC and 1 LED 18W tubelight. It ran fine for 2 hrs, which is when I turned on the power supply again. (it means it had capacity to continue...

Hello, Around 1 year back, My total electricity consumption per month was 4 to 4.5 units per day. Somehow, it increased to 6.5 to 7 units per day over the last 6 months without any new electric fitments or uses. So I got into trial & error checks by keeping 1 appliance off each day and...

Do we have any inputs on the availability of these kind of chargers which can be purchased and operated to charge the batteries at the standard 240V home voltage? I mean, batteries are being used everywhere - bikes, cars, inverters/UPS. This problem of battery going dead (or being told so by...

Thanks a lot everyone for the inputs over the last few days. I finally had the inverter-battery setup checked with a "borrowed" multimeter. It was showing 4V only. After having it charged by the battery person for more than 14 hours, it still did not bump up the voltage to the required 12+...

Yesterday afternoon. So, How should I proceed here here? Should I keep it connected with inverter for few more hours/days? Or give it to the battery charging guy, or go for a replacement?

Thanks again @blr_p for the inputs. 2 cells on the left were full, two in the middle were at 75%, while rest 2 at the right were at 50% water level. Unfortunately, I dont have a multimeter, but the battery person who visited last told that it was around 4 V.... (I couldnt see that reading so...

OK, so I should have added this in my previous reply. I have fully filled up each cell of the battery with distilled water yesterday afternoon, and left it connected with my inverter switch ON (27 hours now). But the inverter LED indicators are not turning ON at all till now. Around 30 minutes...

Battery is 135 Ah and around 5 years old. However, it was working perfectly till before going on leaves. Was powering multiple fans and tubes for 3+ hours. So I doubt if it is really dead and that's the whole reason for seeking help.

Hello, Thanks for the response. It is a tubular battery. The person who came to check the battery said that it has around 4 Volts remaining and is telling that the battery is dead. Given that he himself is a battery seller, is there anything else that I can check or try to get it working...

Hello, My Su-Kam inverter has apparently stopped working. Need some advice on what could be going wrong. Before going on leaves, I had charged the battery fully, and then disconnected the inverter power connection from the mains. After coming back, I reconnected the power to main line and...
