Frequently Asked Questions down arrow

A regular inverter battery is built for occasional backup during power cuts and works best with partial discharges. An Okaya Solar Battery is engineered for deep-cycle, daily use—it's designed to be charged and discharged every day as part of a solar system, handling both partial and full discharges efficiently for longer, more reliable renewable energy backup.

AEMS (Advanced Electrolyte Management System) keeps electrolyte levels consistent across all cells, drastically cutting down how often you need to top up water.

Paired with Water Level Indicators (WLI) on each cell, it makes maintenance spill-free, cleaner, and far less frequent—a genuine convenience advantage over older battery designs.

C10-rated means the battery is designed to deliver its full rated capacity over a 10-hour discharge period—the industry-standard benchmark for solar battery performance.

All Okaya Solar Batteries are C10 rated, ensuring consistent and predictable backup performance for solar applications.

Okaya Solar Batteries range from 40Ah to 200Ah, so the right size depends on your daily energy usage and how many hours of backup you want overnight or during outages.

Larger households or systems with bigger loads typically need higher-Ah batteries. Our team can help you match the right battery capacity to your actual energy requirements before you buy.

Okaya Solar Batteries come with either a 36-month or 60-month warranty, depending on the model.

Built with Advanced Tubular Technology (ATT), they offer better deep-discharge recovery and longer cycle life. Actual battery lifespan depends on usage patterns, charging habits, and maintenance, but the ATT design is specifically built to handle the repeated daily cycling that solar applications demand.

Yes. Okaya Solar Batteries use:

  • Spill-proof PPCP containers
  • Robust terminals
  • Compliance with IS 16270 and IS 13369 safety standards

They do release hydrogen gas while charging, so proper ventilation is essential. Only distilled water should be used for top-ups—never tap water, which can damage the battery cells over time.
