• Back up at 300W: ≥ 2 hrs : 40 mins
The weight difference itself is negligible for performance — both deliver essentially the same backup time (approximately 2 hours 40 minutes at 300W). The meaningful difference is the warranty tier (60 vs 36 months), with the marginal weight increase reflecting whatever internal construction difference supports that longer coverage period.
At 120Ah with roughly 2 hours 40 minutes of backup at 300W, it suits moderate household loads — a few lights, fans, and a TV or similar electronics together. For larger 3BHK homes with heavier combined loads (multiple rooms, larger appliances), you may want to compare your actual total wattage against this rating before deciding if 120Ah is sufficient or if a higher capacity makes more sense.
Ensure all batteries in the bank are the same age, same model, and ideally purchased together — mixing batteries of different ages or wear levels in parallel can cause uneven charging and shorten the lifespan of the newer units. Consult your installer on proper series/parallel wiring for your specific voltage needs.
At 412mm in height and 54kg in weight, it needs more vertical clearance than flatter battery formats, plus a stable, adequately rated base. Confirm your installation space (under-counter, utility room, etc.) has sufficient height clearance before purchase, particularly in compact installation spaces.
No — the warranty length doesn't change the maintenance requirement. Regular water checks, distilled water only, clean terminals, and proper ventilation remain necessary regardless of warranty tier; skipping maintenance can void warranty coverage even within the covered period.
Manufacturing defects under normal use conditions for 60 months from purchase. Confirm specific registration requirements and maintenance conditions with Okaya Customer Care to ensure coverage remains valid throughout the period.
