The existing blog title calls the Okaya Super Jumbo Tubular (SJT) the best inverter battery in India, but which battery is best depends on your load, space and backup hours, and Okaya's data does not include an independent ranking. This guide lists what Okaya states about SJT so you can judge it for your own needs, as one option in Okaya's tubular inverter battery range.
Okaya's SJT product page lists these features. They are Okaya's own descriptions:
1. A 100% tubular battery in a Super Jumbo container, with a compact footprint compared with an equivalent Tall Tubular battery.
2. Corner protection and securely fitted terminal protectors for added safety.
3. A vent-plug design that prevents spills, and a float design for spill-free water topping without removing the float plug.
4. A 6x1 layout with all water inlets on one side, and six ceramic water-level indicators.
5. Taller tubular plates, which Okaya states give better performance, longer backup and easier water top-up than traditional Jumbo Tubular batteries.
6. Charging about 15% faster than conventional Jumbo Tubular batteries.
7. XBD+ and Certified Backup Hours.
8. 99.98% pure lead, pressure die-cast terminals and a PE envelope separator.
9. Factory-charged, ready to use, with paperless warranty registration.
Four models cover 110Ah, 140Ah and two 160Ah variants (48-month and 60-month). Total warranty across the SJT range is 48 to 60 months, made up of a flat period and a pro-rata period.
Okaya makes two direct comparisons with conventional Jumbo Tubular batteries: the 15% faster charging and the taller plates. Okaya's data does not list other Jumbo Tubular figures, so compare the specification sheet of the Jumbo Tubular battery you are considering. A fuller comparison is in SJT vs Jumbo Tubular batteries.
Okaya declares Certified Backup Hours for each model, tested under the UMHD (Urban Metro Heavy Duty) load cycle in NABL-accredited laboratories and printed on the packaging. In hours:minutes, at 400 W, 300 W, 200 W and 100 W:
1. 110Ah SJT: 1:45, 2:45, 4:55, 11:30.
2. 140Ah SJT: 2:30, 3:50, 6:35, 15:05.
3. 160Ah SJT, 48 months: 3:00, 4:30, 7:50, 17:20.
4. 160Ah SJT, 60 months: 3:05, 4:40, 8:00, 18:40.
Okaya states that XBD+ gives up to 15 to 20% longer backup than a conventional tubular battery of the same Ah capacity, and that real backup varies with temperature, battery age, the inverter used and state of charge.
Okaya states that most models need only 1 to 2 water top-ups a year. Use the water specified in the product manual or by Okaya Care for your model.
It depends on your wattage and space. SJT batteries from 110Ah to 160Ah measure 540 x 210 x 317 mm, and Okaya suggests around 160Ah for a typical 2BHK. For larger loads, Okaya's range also includes TT models up to 310Ah. Add up your wattage, compare declared hours, and see SJT inverter battery for home for the models in detail. The inverter battery details for each model are on the product listing.
Warranty registration is paperless, and Okaya lists an all-India onsite service network. Message Okaya Care on WhatsApp at +91 9818 909090, write to care@okaya.in, or use the dealer locator to find nearby Okaya dealers in your area.
