When you ask how long an inverter battery will last during a power cut, the answer in most cases is usually an estimate based on Ah rating and general assumptions. But actual backup performance depends on several operating and engineering factors beyond just stored capacity.
Okaya introduced CBH — Certified Backup Hours — to bring more transparency to inverter battery backup. Instead of relying only on estimated backup assumptions, users can now view tested runtime values under defined load conditions, verified through NABL-accredited third-party laboratory testing and printed directly on the battery packaging before purchase.
Most inverter batteries are compared primarily on Ah (Ampere Hour) rating. While Ah indicates how much energy a battery can store, it does not fully explain how long appliances will actually run during a power cut.
A measure of how much energy a battery can store. It reflects stored capacity — not actual runtime under real operating conditions.
Actual backup performance also depends on several additional factors such as battery plate design, internal construction quality, charging condition, and appliance load during usage. Because of these factors, two batteries with similar Ah ratings may still deliver different runtime performance during actual operation.
This is where Certified Backup Hours becomes important.
The actual runtime of an Okaya inverter battery tested under specific and controlled load conditions, verified through NABL-accredited third-party laboratory testing, and printed clearly on the battery packaging.
Unlike general backup assumptions, CBH values are scientifically measured under controlled charge and discharge conditions to help users understand expected runtime more transparently before purchase.
Each Certified Backup Hour value is:
1. Tested under defined load conditions
2. Verified through NABL-accredited third-party laboratories
3. Measured using controlled testing parameters
4. Printed clearly on the battery packaging for comparison
This gives homeowners a more reliable reference point while selecting an inverter battery for home backup requirements.
Okaya introduced CBH to bring measurable backup transparency to the inverter battery category.
Instead of depending only on estimated backup discussions, homeowners can now view tested backup values measured under controlled conditions and printed directly on the packaging for easier comparison before purchase.
This makes Okaya the first inverter battery brand in India to declare Certified Backup Hours on packaging through verified and standardized testing procedures.
Ab Backup Guess Nahi. Verify Karo.
CBH values are tested under standardized operating conditions designed to create measurable and comparable runtime values across battery models.
Okaya’s standardized test protocol based on typical Indian household load conditions. CBH values are validated under UMHD testing conditions.
Standard Test Parameters
| Parameter | Value |
| Charging Method | Constant current till TOC ≥15.5V |
| Open Circuit Voltage (OCV) | 12.50–12.70V |
| Specific Gravity | 1.25–1.26 |
| Temperature | 27±2°C |
| Cut-off Voltage at Discharge | 10.5V |
These controlled parameters help maintain consistency in runtime testing and allow customers to compare backup values more transparently across different battery models.
| Factor | Standard Inverter Battery | Okaya CBH Battery |
| Backup Information | Ah rating only | Certified Backup Hours at defined loads |
| Basis of Backup Value | General estimate | NABL accredited third party lab tested and verified |
| Packaging Information | Ah and warranty | Ah, warranty, and CBH values |
| Load Conditions Mentioned | Usually not specified | Tested under UMHD conditions |
| Comparison Before Purchase | Based on assumptions | Based on verified runtime data |
| Transparency | Limited | Verified backup information on packaging |
Backup hours are not fixed numbers. Runtime changes depending on the connected load during a power cut.
For example, a battery operating at 300W load conditions will naturally provide longer backup compared to the same battery operating at 600W load conditions.
This is why Okaya CBH values are measured against specific watt conditions such as 100W, 200W, 300W, and 400W. It helps homeowners understand expected backup performance more realistically based on actual usage patterns.
Instead of depending only on capacity numbers, users can compare tested runtime values under standardized operating conditions.
Okaya CBH batteries are integrated with XBD+ Technology (Xtra Backup Design Plus), designed to support longer and more dependable backup performance.
The batteries are engineered using advanced active material composition and optimized internal battery engineering to help improve, charging response, and runtime delivery during power cuts.
Okaya offers XBD+ with CBH across:
A. Super Jumbo Tubular (SJT) series
B. Tall Tubular (TT) series
covering household backup requirements as well as higher-capacity applications for larger homes and heavier power loads.
Certified Backup Hours provide a verified reference point under controlled testing conditions. However, actual runtime in real-world usage can still vary depending on several practical factors including:
1. Appliance load during operation
2. Ambient temperature
3. Battery age
4. Charging conditions
5. State of Charge (SOC)
6. Usage patterns
Charging through an inverter may not always result in 100% State of Charge, and backup performance on a new battery may stabilize further after multiple charge-discharge cycles.
CBH helps homeowners compare tested backup values more transparently, while real-world runtime depends on actual operating conditions inside the home.

CBH stands for Certified Backup Hours. It represents the tested runtime of an Okaya inverter battery under defined load conditions verified through NABL-accredited third-party laboratory testing and printed on the battery packaging.
Ah (Ampere Hour) indicates stored battery capacity. CBH helps users understand expected runtime at specific load conditions under standardized testing procedures.
Okaya CBH batteries are tested under UMHD conditions using controlled parameters including temperature, voltage, specific gravity, and defined watt loads.
Yes. Certified Backup Hours are printed directly on the battery packaging to help homeowners compare tested runtime values before purchase.
CBH values are verified runtime references measured under controlled testing conditions. Actual runtime can vary depending on appliance load, temperature, charging condition, battery age, and usage pattern.
Okaya XBD+ inverter batteries across SJT and TT series are available with Certified Backup Hours.
Homeowners can explore Okaya inverter batteries through www.okaya.in or by sending “Hi” to +91 9818909090 on WhatsApp to compare products, locate dealers, and access support assistance.
Ah rating tells you how much energy a battery can store. Certified Backup Hours helps explain how long that energy is expected to support your home under defined operating conditions.
By combining controlled testing, NABL-accredited lab verification, and packaging-based transparency, Okaya CBH Technology helps homeowners compare inverter battery backup more confidently before purchase.
For users looking for a more informed and transparent approach to power backup selection, Certified Backup Hours provides a clearer way to evaluate inverter battery performance beyond just Ah capacity.
