– Use energy saving devices.
– Turn off extra devices or appliances if not in use.
– Connect bigger or more batteries to your UPS / Power Inverter.
– Change old and worn out batteries.
People use power backup devices to cope with power outages that are caused by either bad weathers or scheduled load shedding. UPS (uninterrupted power supply) and Power Inverter are two commonly used electric power backup devices that are capable of supplying electric current to keep electrical and electronic devices working. Their use varies from running computer servers, fans, lighting and all sorts of home appliances. Computer servers no matter they are larger for commercial use or smaller for official or residential use, they are always connected with UPS to protect their running activity and keep them always online in case of power failure. A standby generator is also always kept ready in case of extended power outage or black out.
There is a small difference between a UPS and a Power Inverter. UPS carries built in batteries packed inside the enclosure for a limited supply of backup. Whereas Power inverter can be connected with a wide sizes of batteries or battery banks depending upon the needs. Before buying a UPS or power inverter, you should calculate how much backup you need. Then a purchase should be made. Below are some useful guidelines and tips to increase the backup of your power backup device.
1- If you own a smaller UPS or Power Inverter with smaller battery, the backup time will be shorter. What you can do is decrease your average power consumption by disconnecting or turning off extra load when not needed. More the load you put, more the power will be sucked out of batteries and shorter will be the backup period. So, try to manage your needs to extend the backup.
2- UPS that contains built in batteries can be opened and connected with larger external batteries as well. Make sure you buy similar voltage batteries made with similar chemistry as that of UPS’ built in batteries. Power inverters can be connected easily with larger batteries without any hassle. Additionally, by connecting several batteries in series-parallel, larger battery packs can be made which can be used to extend the backup.
3- Use energy saving devices only. Ordinary bulbs consume 75 % more electricity but gives the similar brightness as CFL lamps give. To further cut the load, use LED lights. LEDs are the most energy saving light producing devices which are now widely used due to the low power consumption and extremely long service life. Newer fans made with better copper winding also consumes lesser power. Poor quality wiring increases the resistance thus increasing the load on UPS and affects the backup. Use good quality copper wires only.
4- Latest gadgets consume fairly lesser electricity than older gadgets. New LED televisions, computer monitors and new technology based CPUs, they all consume very low power. Servers should be upgraded for efficiency and power saving. The use of SSDs inside them can further cut the load. UPS in which larger batteries can not be installed, such upgradation can help or you may go for a larger UPS instead.
5- Change the batteries if they are worn out. Batteries lose their designed capacity over time thus reducing the backup. Buy good quality batteries only which will last longer and also guarantee the correct charge storage capacity. Poor quality batteries fails prematurely, does not offer better backup, and are simply waste of money. SLA batteries (sealed batteries) are best suited for installing inside the enclosure as these won’t leak the electrolyte. Power inverters can be connected with flooded lead acid batteries as well. There are other types of batteries as well like lithium batteries which can be used if the Power Inverter or UPS manufacturer recommends their use. Lithium (ion and polymer) batteries are the most efficient batteries available today in reasonable price.

Ref. to HOW TO EXTEND UPS & POWER INVERTER BACKUP
Hi there.
Thanks for your info which is very interested.
Now I am going to ask some questions.
I have an old UPS with dead battery inside it. I decided to remove such battery and replace it with a 12v car battery. Then when I try to use the UPS as an inverter everything goes fine and same works fine but it’s only stays on for five minutes.
I’m thinking that it might be some kind of setting inside the UPS which command the UPS system to switch off automatically after these five minutes.
So my question is:-
Can I increase the time limit of back up for example 1 hour or more? Can I eliminate that setting and let the UPS on for a couple of time on back up mode?
Talal A.
Connect bigger battery and try. I am suspecting the car battery you are using is also weak.
UPS will continue supplying backup as long as battery voltage does not fall below threshold. Then it shutdown. 5 min backup is the indication the battery you have connected is also weak or it is not getting charged properly.

please sir how do i extend the battery of my blue gate 1200va ups with bigger battery. it has two series connected 12v 7ah battery inside it. please using a large 24 volt thousands amp deep circle battery will it be perfect. and how do i charge the batteries please?
Talal A.
There are no 24V lead acid batteries. Buy two larger 12 V batteries and place them outside the UPS. Remove terminals from internal batteries and connect them with external batteries in series. Buy proper gauge cables if you need to extend the internal battery cables.
See this post how to connect in series: http://benignblog.com/2012/04/how-to-make-battery-banks-battery-packs-faqs.html
kellysmartboy
am grateful of your reply. so like how many amps will be much for such ups so that i will not exceed to the one that may burst the unit. for example (24v(12*2) 10,000 amps) is it ok or much and the charger of the ups, can it charge the battery
Talal A.
I will recommend to go for batteries not bigger than 50 Ah each.
Buy two batteries of same brand and equal capacity.

i have been getting only 40 sec backup in my WEP UPS. can u help?
Talal A.
How old are your UPS batteries? If they are quite old, changing them will resolve the problem.

What specific features are required in inverter to connect two battery of 12 v each?
Talal A.
It should either require 24v battery input or you may connect two batteries in parallel with 12 v inverter.
Vikas
If adding more batteries then will it not affect the circuits and output of the ups?
Talal A.
Adding in parallel won’t. Adding in series will damage the inverter.

I have 10kv UPS with currently 16batteries of 26AH and it gives hardly 20 minutes back up for 35 desktop. what is the next step to get at least one hour back up
Talal A.
Add more batteries.

I have a 3.5 kva inverter with 4 batteries, used it for over 3 years and my batteries are almost brand new. Currently my inverter or batteries cannot give me power for 2 straight hours. What do you advice. Thank you
Talal A.
Check batteries and inverter individually to figure out which of them is actual culprit.

I bought luminous red charge 25000 200ah battery and luminous ecovolt 1050 inverter..When installed inverter charged battery for few minutes and charging indicator went off.But we were told to charge it for at least 12 hours before use.We used it and it gets charged well but after full charge if power supply goes off and comes again inverter charges again for some time with boiling sound coming from battery and charging indpicator goes off.Is this sound normal.Also this new battery only gave backup of only 10 hours for only 20 watt load..what is wrong with battry…what to do.,please guide.
Talal A.
Full charge it and test it by putting a relatively heavier load like may be a fan or some other device. Test how much backup that battery supplies then. You must be aware of device power consumption for accurate analysis.

My 1500VA,24V Sukam inverter produces a whistling sound when it works. What should be changed to solve this problem?
I wonder if the large consumed power in my inverter was as a result of this problem! It needs 1.6A to operate with no load..
I’ll be grateful for your urgent reply.
Talal A.
Are you sure it is not fan noise?

Respected sir,
I have 1.5kva ups in which pic16f72 used there was problem in current control, so what is solution?
Jason Russel
Thanks for this informative post Talal! Most people prefers buying ups and inverters with low even if they would like higher backup because of the big difference in the price. I am an example as I use a low end Staticon stativolt inverter. People would definitely like to improve the limited backup they could avail from their ups and power inverters. The tips mentioned in this article is very effective and helpful for everyone.

I have purchased Inverex 2200 va ups 3 months back,last night it stopped working (suppling power).I immediatly restarted it,till now it is working fine Alhamdulila.I want to know that it was due to weak battery or due to ups internal fault.
Talal
Check the battery terminals for loose connection.
