The Okaya OPTT34060 is Okaya's largest 310Ah Tall Tubular inverter battery. Priced at ₹32,000 and backed by a 60-month warranty, it is designed for large homes, commercial establishments, small offices, and other heavy-duty applications where standard residential batteries up to 260Ah are not sufficient. It is typically paired with a high-capacity inverter or an Okaya Hi-Capacity UPS.
As per Okaya's CBH (Certified Backup Hours) declaration, independently verified by NABL-accredited laboratories under UMHD conditions, the OPTT34060 delivers: 9 hours 45 minutes at 300W load, 6 hours 40 minutes at 400W load, 5 hours 10 minutes at 500W load, and 3 hours 45 minutes at 600W load.
With its 310Ah capacity, the OPTT34060 is engineered for heavy-duty residential and commercial applications where connected loads are significantly higher than those of a standard home. Testing at 100W or 200W would not accurately represent its intended use. Therefore, Okaya's CBH testing for this model focuses on the 300W–600W range, reflecting the real-world operating conditions for which it is designed.
At a 400W load, the OPTT34060 provides 6 hours 40 minutes of backup compared to the OPTT29066's 6 hours 15 minutes. Its additional 50Ah capacity becomes even more valuable at higher loads. For example, at 600W, the OPTT34060 still delivers 3 hours 45 minutes of backup—a load level at which the 260Ah model is not tested—highlighting that the 310Ah battery is built for a substantially heavier-duty category of applications.
The OPTT34060 features a 310Ah / 12V Tall Tubular design with dimensions of 510 × 215 × 413 mm and a net weight of 79.9 kg. It is Okaya's heaviest inverter battery and should be installed on a heavy-duty battery stand capable of supporting its weight. The battery is factory charged and ready for immediate installation and use.
