Power cuts are still a regular challenge in many small towns and growing cities, so the right UPS battery is the one that gives the tested backup you need, takes little upkeep and has support within reach. Okaya's inverter batteries are built around those three points: backup hours that are tested and declared, low-maintenance water topping and a service network you can reach by dealer locator, WhatsApp or email. This guide shows how to pick the right capacity and what support to expect.
Three things matter most:
1. Tested backup: choose a capacity using declared backup hours at your load, not Ah alone.
2. Low upkeep: fewer water top-ups and easy level checks mean fewer occasions when you need help.
3. Reachable support: a nearby dealer, an easy warranty process and a way to book a service visit.
Okaya's tubular inverter battery range comes in Super Jumbo Tubular (SJT, 110Ah to 160Ah) and Tall Tubular (TT, 160Ah to 310Ah) formats, plus a 90Ah compact model. Okaya suggests these capacities as a starting point:
1. 90Ah: compact needs.
2. 160Ah: a typical 2BHK home, available in both SJT and TT.
3. 210Ah: larger homes that need longer backup (TT).
4. 260Ah: heavy loads (TT).
5. 310Ah: commercial use such as shops and offices (TT).
Add up the wattage of the fans, lights and appliances you want to run with the load calculator, then match it to a capacity. For a fuller walk-through, read which inverter battery is best for home.
Space matters too. An SJT container is 317 mm high, while a TT container is 404 mm high (413 mm at 310Ah), so check the shelf or trolley height before you buy. You can compare the inverter battery size of every model in Okaya's listing, and the Super Jumbo Tubular vs Tall Tubular batteries guide explains the difference between the two formats.
Certified Backup Hours (CBH) are the backup times Okaya declares for each battery at set loads. They are tested under the UMHD (Urban Metro Heavy Duty) load cycle in NABL-accredited laboratories and printed on the packaging, so you can match a battery to your load instead of guessing. Examples from Okaya's Certified Backup Hours figures, in hours:minutes:
1. 90Ah, 48 months (24+24): 3:25 at 200 W, 8:10 at 100 W.
2. 160Ah TT, 60 months (36+24): 8:45 at 200 W, 20:15 at 100 W.
3. 210Ah TT, 60 months (36+24): 12:05 at 200 W, 28:10 at 100 W.
4. 260Ah TT, 66 months (42+24): 15:05 at 200 W, 32:40 at 100 W.
5. 310Ah TT, 60 months (36+24): 6:40 at 400 W, 9:45 at 300 W.
The 310Ah model is tested at higher loads (600 W to 300 W), so its figures are not directly comparable with the others. Real backup varies with temperature, battery age, the inverter used and state of charge. The standard test conditions are constant-current charging until terminal output reaches 15.5V or above, specific gravity of 1.25 to 1.26, open circuit voltage of 12.50 to 12.70V, a 10.5V cut-off and a test temperature of 27 +/- 2 degrees C.
Okaya states that most models need only 1 to 2 water top-ups a year. Every battery has six ceramic water-level indicators, so you can check levels without opening the cell. SJT batteries have all water inlets on one side in a 6x1 layout, and TT batteries use a vent-plug and float design for spill-free topping. Use the water recommended in the product manual or by Okaya Care.
Total warranty is 48 to 66 months, depending on the model, and combines a flat and a pro-rata period. Warranty registration is paperless, and you can register your warranty online. Okaya offers PAN India onsite service, and you can book a complaint online. For help, message Okaya Care on WhatsApp at +91 9818 909090 or write to care@okaya.in.

Which inverter battery is best for a home in a small town?
Okaya suggests around 160Ah for a typical 2BHK and 90Ah for compact needs. Add up the wattage you want to run and check the declared backup hours at that load before you choose.
How many hours of backup will an Okaya battery give during a power cut?
It depends on the capacity and the load. For example, the 160Ah TT with a 60-month warranty is certified at 8:45 at 200 W and 20:15 at 100 W. Real backup varies with temperature, battery age and the inverter used.
Do Okaya inverter batteries need a lot of maintenance?
No. Okaya states that most models need only 1 to 2 water top-ups a year, and six ceramic water-level indicators help you check levels.
Can I use an Okaya inverter battery for a shop or office?
Yes, within the load it is sized for. Okaya suggests 260Ah for heavy loads and 310Ah for commercial use such as shops and offices. Add up your total wattage first to confirm the capacity.
What warranty do Okaya inverter batteries come with?
Total warranty is 48 to 60 months on SJT models and 48 to 66 months on TT models, combining flat and pro-rata periods.
How do I find an Okaya dealer near me?
