This model delivers approximately 2 hours at 300W versus the 075H's 1 hour 40 minutes, despite identical 75Ah capacity — small construction and design differences tied to the longer 60-month warranty tier can result in marginally different real-world backup performance, even at the same rated capacity.
It's a modest difference, but worth noting for mounting — ensure your battery stand, trolley, or shelf is rated for at least 40kg with some margin, standard practice regardless of which specific model in this weight range you choose.
It matches the warranty tier offered on the S-suffix models across most capacities in the range (040S, 100S, 120S, 150S, 200S all carry 60 months) — so the warranty length itself doesn't vary by capacity, only by which suffix variant you choose within each capacity.
At 75Ah, it comfortably handles lighter, sustained loads like LED lighting, fans, and device charging for several hours, but isn't sized for running power-hungry appliances like refrigerators or pumps for extended periods — match your specific load list against the 300W backup rating before relying on it for heavier equipment.
No — the maintenance approach is identical across the ATT range: periodic water level checks via the ceramic indicators, distilled water only for top-ups, clean and tight terminals, and adequate ventilation. Capacity doesn't change the maintenance routine, just the backup duration you get from following it.
It covers manufacturing defects for 60 months under normal use. Many battery warranties require registration or proof of professional installation to remain valid — confirm the specific registration process with Okaya Customer Care or your dealer at the time of purchase.
