At 51.4kg versus the 100H's 39kg, this is a genuinely different physical format — Tall Tubular (TT) construction with taller, narrower dimensions (508×190×412mm vs 532×221×284mm). The TT format generally supports a longer service life and the extended 60-month warranty, but it does require more vertical installation space and careful handling given the added weight.
Yes — given the height (412mm) and the weight concentration, a stable, wide-base stand or trolley rated for this weight class is important, more so than with the flatter 100H format, since a narrower footprint with significant height and weight needs solid support to avoid tipping risk.
This model delivers approximately 2 hours 30 minutes at a 300W load, while the 100H is rated at roughly 3 hours 30 minutes at a lower 100W load — these are tested at different load levels, so direct comparison requires converting to your actual intended load rather than comparing the headline backup figures directly.
TT construction is generally associated with deeper plate design supporting longer cycle life, which aligns with why this format pairs with the longer 60-month warranty across Okaya's range — but actual longevity in your specific installation still depends heavily on maintenance, charging discipline, and avoiding chronic deep discharge.
The same routine applies — periodic water level checks through the ceramic indicators, distilled water only, clean and tight terminals, adequate ventilation. The TT format doesn't change the maintenance steps, only the physical handling considerations given its taller, heavier build.
Manufacturing defects under normal use conditions for 60 months from purchase. As with other models in the range, proper installation and maintenance are typically required to keep coverage valid — confirm specific registration steps with Okaya Customer Care.
