• Capacity @C10: 150Ah
• Dimensions: Length*Width*Total Height = 508 * 190 * 412 mm (±2 mm)
• Net weight: 58.90 kg (±3%)
• Warranty: 36 months
• Back up at 400W: ≥ 3 hrs
At a 400W load, this battery delivers approximately 3 hours of backup — a reasonable evening window for combined loads like lighting, fans, and a TV or similar electronics. If you need backup well beyond 3 hours at that load level, you'd want to compare against the 200Ah tier instead.
This is a genuinely heavy unit — get help moving and positioning it rather than attempting it alone, place it on a stable, level, properly rated surface or stand, and ensure your installation space has the floor strength and clearance for both the weight and the 412mm height of the Tall Tubular format.
Same 150Ah capacity and identical backup performance (3 hours at 400W for both), but the 150S carries a 60-month warranty versus this model's 36 months, and interestingly weighs slightly less (56.5kg vs 58.9kg) despite the longer warranty — worth comparing both factors rather than assuming heavier always means longer-lasting.
Possibly, depending on your refrigerator's actual wattage — add up your refrigerator's running wattage plus lighting and other essentials, then compare the total against the 400W backup rating. If your combined load exceeds that figure, actual backup time will be shorter than the rated 3 hours.
It doesn't differ in steps, only in scale — more cells mean more water level indicators to check, but the same process applies: periodic visual checks via the ceramic indicators, distilled water only, clean tight terminals, and proper ventilation, done consistently every 1–3 months.
Manufacturing defects under normal use conditions for 36 months from purchase, with proper installation and maintenance typically required to keep coverage valid — confirm exact terms with your dealer.
