It means if your battery fails after the free replacement period but within the warranty, you get a new battery at a discounted price, based on how much warranty is left.

Okaya inverter batteries come with a spill-free float design and Advanced Electrolyte Management System (AEMS). The float plug moves with the water level—

• If the float is up, the level is sufficient.
• If it drops down, the battery needs a top-up

Simply add distilled/demineralised (DM) water through the float opening until the float rises back. There’s no need to remove the full vent plug. Keeping the right level prevents plate exposure, loss of backup, and long-term damage.

Tap water contains minerals and impurities that cause sulfation/corrosion, reducing life and backup. Use distilled/DM water only.

Typical check every 1–3 months depending on usage/temperature. Okaya’s AEMS + low-antimony design reduces water loss; still, follow periodic checks.

Okaya batteries come with heavy-duty embedded terminals that resist rust and breakage. Just keep the terminals clean and tight and apply a little protective jelly/grease as recommended. Always use the right cable size and tighten properly—this keeps the connection safe and backup consistent.

Reduced backup, slow charging, or inverter warnings indicate the battery may require attention. Health can be verified through a multimeter check or a professional load test by an Okaya authorized technician. For support, contact Okaya Customer Care:
