Okaya's Advanced Inverter Battery range is a line of tubular batteries for homes, shops and offices, available from 90Ah to 310Ah. It combines tubular plate construction with XBD+ for longer backup, Certified Backup Hours (CBH) for tested runtime, and a low-maintenance design. This introduction explains what the range includes, how the formats differ and which capacity suits which home. If you are comparing a tubular battery for your inverter, start here and then go deeper using the guides linked below.
It is Okaya's current range of tubular inverter batteries, built in three container formats: JXT, SJT (Super Jumbo Tubular) and TT (Tall Tubular). The range has 9 capacities, 90Ah, 110Ah, 140Ah, 160Ah, 190Ah, 210Ah, 230Ah, 260Ah and 310Ah, with total warranties from 48 to 66 months depending on the model.
Okaya has also upgraded its older 100Ah, 150Ah and 200Ah batteries to 110Ah, 160Ah and 210Ah, with no change in physical size or compatibility.
The formats differ mainly in height, capacity range and how you top up water.

The inverter battery size you need depends on the space available and the capacity you choose, so check the dimensions on the product page before buying.
Okaya states that SJT batteries recharge about 15% faster than conventional Jumbo Tubular batteries.
Okaya lists these features for its tubular inverter battery range:
1. Rugged body design with corner protection and securely fitted terminal protectors.
2. Spill-free water topping, with 6 ceramic water-level indicators so you can check levels without opening the cell.
3. Low-antimony alloy, which reduces water loss and maintenance. Okaya states that most models need only 1 to 2 water top-ups a year.
4. Factory-charged batteries, paperless warranty registration and PAN India onsite service.
XBD+ (Xtra Backup Design Plus) uses an advanced active material composition and internal design to improve how stored energy converts to usable power. Okaya states it gives up to 15 to 20% longer backup than a conventional tubular inverter battery of the same Ah capacity. You can read more on Okaya's XBD+ technology page.
Certified Backup Hours are the backup times Okaya declares for each battery at specific loads. They are tested under the UMHD (Urban Metro Heavy Duty) load cycle in NABL-accredited laboratories and printed on the battery packaging, so you can compare tested runtime instead of estimating from Ah alone. Full figures are on the Certified Backup Hours page. Real backup still varies with temperature, battery age, the inverter used and state of charge.
