• Warranty: 60 months
• Back up at 400W: ≥ 4 hrs 10 mins
Among the models listed here, this is the highest capacity (200Ah) paired with the longer warranty tier (60 months), delivering approximately 4 hours 10 minutes of backup at 400W — if maximum backup duration and warranty length are both priorities, this sits at that combination within the range.
At 65.5kg versus the 200H's 63kg, the additional weight likely reflects construction differences supporting the longer 60-month warranty period — both deliver identical rated backup performance, so the weight difference relates to durability design rather than capacity or output.
This capacity tier suits larger households with multiple essential loads (lighting across several rooms, fans, a refrigerator, entertainment electronics) wanting several hours of meaningful backup, or smaller commercial setups like shops needing to maintain operations through extended outages — it's a step up from what a single-room or minimal-load setup would require.
Yes — confirm your PCU or inverter's charging current rating can properly charge a 200Ah battery within a reasonable time, verify your wiring gauge is adequate for the current involved, and ensure professional installation handles the earthing and ventilation requirements appropriately for a battery this size.
Watch for backup time noticeably shorter than the rated 4 hours 10 minutes even after a full charge, unusually long recharge times, or frequent low-battery warnings despite correct water levels and load — these are signs worth having a technician check, particularly as the battery approaches or exceeds its warranty period.
Manufacturing defects under normal use conditions for 60 months from purchase. Confirm specific registration requirements, installation conditions, and maintenance obligations with Okaya Customer Care to ensure coverage remains valid throughout the full period.
