UPS Battery Price in Pakistan: Every Battery for Home UPS and Inverters

What kind of battery does a UPS use?

A home UPS or inverter in Pakistan runs on 12V lead-acid batteries. There are three main types:

• Tall tubular: the best for long daily loadshedding. See tubular batteries (Tubular Battery).
• Flooded flat-plate deep cycle: a lower-cost choice for shorter cuts. Examples are Exide HP (50Ah to 200Ah), Phoenix UGS and UGLT (65Ah to 225Ah), Osaka HT-IPS and IPS Gold (120Ah to 175Ah), Volta V IPS (120Ah to 175Ah), AGS DC Power Hub (85Ah to 185Ah) and Daewoo DSS (85Ah to 210Ah).
• Sealed dry: no water and no fumes. See dry batteries (Dry Battery).

Many people say "inverter battery"; it means the same thing.

How many batteries does my UPS need?

Check the battery voltage on your UPS label:

• 12V UPS (usually up to about 1 kVA): one battery.
• 24V UPS or inverter (often 1.5 to 3 kVA): two batteries in series.
• 48V inverter (bigger solar systems): four batteries in series.

Always use batteries of the same model and age in one bank. Mixing an old and a new battery shortens the life of both.

UPS battery backup time

Our formula is hours = Ah x 12 x 0.5 x 0.85 / watts. It uses half the capacity, which keeps a lead-acid battery healthy, and allows for UPS losses. For one 12V battery:

• 100Ah: about 1.7 hours at 300W (2 fans, lights, router), 0.85 hours at 600W (fridge plus fans).
• 130Ah: about 2.2 hours at 300W.
• 175Ah: about 3 hours at 300W, 1.5 hours at 600W.
• 200Ah: about 3.4 hours at 300W, 1.7 hours at 600W.

Two batteries on a 24V UPS double these hours at the same load. For a PC, a router or CCTV, even a 65Ah battery lasts a long time.

Tubular or flat plate for UPS?

Flat-plate UPS batteries such as Exide HP 150 (100Ah, 15 plates) or Phoenix UGS-190 (140Ah, 21 plates) cost less and recharge quickly. Tall tubular batteries cost more but cope better with deep daily discharge, so they suit homes with long cuts or solar. If your power goes for one or two hours a day, a flat-plate battery is fine. If it goes for many hours, choose tubular. Our dry vs tubular guide (Dry vs Tubular Battery: Which One Should You Buy?) explains the trade-off in more depth.

Popular UPS battery searches

Shoppers often search by brand plus "for UPS": AGS battery for UPS, Volta battery for UPS, Daewoo battery for UPS and Phoenix tubular battery for UPS. Model searches include Osaka IPS Gold and Osaka IPS 2000. Whatever the brand, compare Ah, plates, type and warranty, not just the name.

Tips to make a UPS battery last

A UPS battery lasts longest when it is treated well:

• Do not overload the UPS. Running a 600W load on a battery sized for 300W shortens both backup and life.
• Let the battery charge fully after each cut. Short, frequent cuts with no full recharge slowly weaken it.
• Keep flooded and tubular batteries topped up with distilled water, never tap water or acid. See how to check battery water (How to Check Battery Water and Top It Up Safely).
• Place the battery in a shaded, ventilated spot, off the bare floor if it is damp.
• Clean the terminals and keep the cables tight.

In summer, check water levels more often, because heat dries out flooded batteries faster.

UPS and battery: buying them together

If you are buying a new UPS and batteries at the same time, decide the battery first. Work out your load and backup hours, pick the battery size, and then choose a UPS whose DC voltage and charger suit that battery. A 1 kVA 12V UPS pairs well with one 150Ah to 230Ah battery; a 24V UPS needs two identical batteries. We sell the batteries with live prices; the UPS comes from its own brand or dealer. Our best battery for UPS guide (Best Battery for UPS in Pakistan: Which One Should You Buy?) gives picks by budget, and the connection guide (How to Connect Batteries to a UPS: Series and Parallel Wiring) shows how to wire a double battery UPS.

Osaka, Exide and Phoenix UPS batteries

The flat-plate UPS ranges most people search for are Osaka HT-IPS (1200 to 2000, 120 to 175Ah), Exide HP (HP 80 to HP 275, 50 to 200Ah), Phoenix UGS and UGLT (65 to 225Ah), Volta V IPS (120 to 175Ah) and Daewoo DSS (85 to 210Ah). They cost less than tall tubular batteries and suit one or two short cuts a day. For long daily loadshedding, a tubular battery (Tubular Battery) lasts longer.
