Okaya's current inverter battery range pairs tubular-plate construction with two Okaya technologies: XBD+ for longer backup and Certified Backup Hours (CBH) for tested, declared runtime. This guide explains what each feature does, how the Super Jumbo Tubular (SJT) and Tall Tubular (TT) designs differ, and how the 90Ah to 310Ah lineup compares on warranty and tested backup, so you can shortlist the best inverter battery for home use on verified numbers rather than Ah ratings alone. Every figure below comes from Okaya's current product specifications.
Four things set them apart: tubular plates built with XBD+ for longer backup, CBH figures that are tested and declared for each battery, low-maintenance spill-free water topping, and a rugged body designed for safe handling and installation. Together they cover the three things most buyers care about: how long it runs, how little upkeep it needs, and how long it lasts.
Tubular construction: 100% tubular batteries with taller tubular plates and Advanced Tubular Technology (ATT), designed for longer battery life under continuous use.
Materials: 99.98% pure lead, pressure die-cast terminals free from voids, a special paste formulation for quick recharge, and a PE envelope separator imported from DARAMIC, USA.
Low maintenance: a low antimony alloy reduces upkeep, and most models need only 1-2 water top-ups a year.
Rugged body: corner protection and securely fitted terminal protectors. On Tall Tubular models, the raised central portion of the top cover protects the terminals in transit and allows safe stacking.
Ready to use: factory charged, so no initial charging is needed, with a paperless warranty process and all-India onsite service support.
XBD+ (Xtra Backup Design Plus) combines an advanced active material composition with optimized internal engineering. It is designed to deliver up to 15-20% longer backup than a standard inverter battery of the same Ah rating, along with faster recharge after a power cut.
Super Jumbo Tubular models also recharge about 15% faster than conventional Jumbo Tubular batteries, which shortens the wait to get back to usable charge between outages. For the engineering behind it, see Okaya's XBD+ technology page, and for what it means in a typical home, the explainer on how Okaya XBD+ delivers longer backup for modern homes covers it end to end.
What Are Certified Backup Hours (CBH), and Why Do They Matter?
Certified Backup Hours are the backup times Okaya declares for each battery at specific loads. They are tested under Okaya's UMHD (Urban Metro Heavy Duty) load cycle and verified by an NABL-accredited laboratory, so you can compare tested runtime instead of estimating it from Ah alone.
Okaya describes CBH as the first declaration of actual backup time at different power loads. The declared figures for every capacity are published on Okaya's Certified Backup Hour (CBH) technology page, and the explainer on why Certified Backup Hours matter in inverter batteries shows how to read them when you compare brands.
How Long Do Okaya Inverter Batteries Back Up at Different Loads?
At a 400W load, declared backup runs from 1 hour 15 minutes on the 90Ah battery to 6 hours 40 minutes on the 310Ah battery. Lighter loads stretch it much further: among models with a published 100W figure, the 260Ah battery has the highest declared runtime at 32 hours 40 minutes. The table below lists every current model's Certified Backup Hours (hh:mm), with all models built on XBD+ with CBH.

The 310Ah battery is declared at higher loads, so it has its own row:
Certified Backup Hours (hh:mm). Backup varies with ambient temperature, battery age, the inverter used and State of Charge (SOC). Charging through inverters does not result in 100% SOC.
To read the table for your own home, pick the load column closest to what you actually run during an outage. If you are not sure of your load, Okaya's load calculator helps estimate the inverter VA and battery capacity before you buy.
SJT is the lower, more compact design and covers 110Ah to 160Ah, while TT is taller and covers 160Ah up to 310Ah. Both use tubular plates, XBD+ and CBH, so the choice mostly comes down to the height you have available, the capacity you need and how you prefer to top up water.
Water topping: SJT places all water inlets on one side in a 6x1 layout, while TT uses a vent-plug and float mechanism designed for spill-free topping.
Monitoring: both carry 6 ceramic water-level indicators, and both typically need only 1-2 top-ups a year.
For a closer side-by-side of the two formats, see the comparison of Super Jumbo Tubular vs Tall Tubular batteries, and for day-to-day upkeep, Okaya's inverter battery care guide covers topping up and routine checks.
Match capacity to your home's size and connected load: 90Ah to 140Ah for compact homes with light load, 160Ah for a typical 2BHK, 190Ah to 210Ah for larger homes or higher daily load, and 230Ah to 310Ah for heavy backup in large homes, offices and shops.
The guide on which inverter battery is best for home walks through this by home type, and the 1BHK, 2BHK and 3BHK power backup guide breaks it down by flat size.
Once you have shortlisted a capacity, you can check the current Okaya battery 160Ah price for the 60-month Tall Tubular model or the Okaya battery 210Ah price for its 60-month counterpart on the Okaya shop, where each page lists its warranty and specifications.
Consider upgrading when your backup has noticeably shortened, the battery is out of warranty, or your load has grown with new appliances or a larger home. A quick health check tells you whether the battery needs replacing or only maintenance.
Okaya's guide on how to check inverter battery health covers the basic checks, and how long an inverter battery lasts explains what affects its working life. Compare your current battery's backup with the Certified Backup Hours above to see what a higher capacity or a longer-warranty model would add.
Current pricing for the full range is listed on the Okaya shop, and the dealer locator helps if you prefer to buy in person.
Prices vary by capacity, warranty tier and running offers, so the most reliable way to compare is the current home inverter battery price listing, where every capacity page shows its warranty and declared backup. To buy in person, find an Okaya battery dealer near you using the dealer locator.
Okaya's advanced inverter batteries are built around three verifiable points: tubular construction with XBD+, backup that is tested and declared as Certified Backup Hours, and low-maintenance, spill-free water topping. When you compare the inverter battery rate across capacities, weigh it against the declared backup and warranty rather than the Ah number alone, and pair the battery with a compatible UPS for home so the inverter and battery are matched to your load.
