An inverter battery is a long-term purchase, and its cost depends on more than the Ah number printed on it. Capacity, series, technology, warranty and how many batteries your inverter needs all change what you pay and what you get back. This guide explains each factor so you can compare options properly, and it shows how Okaya's range is organised. If you are narrowing down the best inverter battery for home use, start with your load and work towards a capacity.
Five things decide the price. The table shows what each one means and how to compare it fairly.
|
Factor |
Why it matters |
How to compare |
|
Capacity (Ah) |
A higher Ah rating stores more energy and generally costs more |
Pick the capacity your load needs, not the largest available |
|
Series and design |
Okaya's range spans JXT, SJT and TT designs across 90Ah to 310Ah |
Match the design to your space and capacity |
|
Technology |
Backup design such as XBD+ affects how much backup you get per Ah |
Look at tested backup hours, not only the Ah rating |
|
Warranty |
Okaya batteries carry 48 to 66 months of total warranty depending on the model |
Compare total months and the flat versus pro-rata split |
|
Number of batteries |
A 12V inverter uses one battery, a 24V inverter two and a 48V inverter four |
Add up the full battery set, not a single unit |
How do you choose the right battery capacity?
Add up the wattage of the appliances you want to run during an outage, decide how many hours of backup you need, and then pick a capacity that covers both. The load calculator helps with the first step. Okaya's suggested use by size is: 90Ah for compact needs, 160Ah for a 2BHK home, 210Ah for larger homes or longer backup, 260Ah for heavy loads and 310Ah for commercial use. Choosing substantially more capacity than your requirement increases the cost and may provide more backup time than you actually need, while too little capacity results in shorter runtime. You can compare options on the inverter battery capacity listing, and the guide on which inverter battery is best for home explains matching a battery to your home in more detail.
These are the features Okaya publishes for its tubular range, and each one affects value over time.
XBD+: Okaya states XBD+ technology gives up to 15 to 20% longer backup than a conventional tubular battery of the same Ah capacity.
Spill-free maintenance: a low-antimony alloy, six ceramic water-level indicators and spill-free topping. Okaya lists 1 to 2 top-ups a year on most models.
Faster recharge on SJT: Okaya states SJT batteries recharge about 15% faster than conventional Jumbo Tubular batteries. Faster recharge does not by itself mean a longer battery life.
Certified Backup Hours: backup times declared at set loads, tested under the UMHD load cycle in NABL-accredited laboratories. They are a comparison guide and do not guarantee the same runtime in every home.
Both are tubular designs. The difference is size and capacity coverage, and it affects where the battery fits.

SJT is the lower design, which suits spaces with limited height. TT is taller and reaches the higher capacities used for larger homes and commercial loads. Measure the space before choosing.
A longer warranty provides extended coverage, but the split between the flat and pro-rata periods matters as much as the total warranty duration. Okaya batteries carry 48 to 66 months of total warranty, depending on the model, and registration is paperless. To compare tested runtime across capacities, see Certified Backup Hours and why Certified Backup Hours matter in inverter batteries.
Yes. The inverter's system voltage decides the battery count. A 12V inverter uses one 12V battery, a 24V inverter uses two and a 48V inverter uses four. Always compare the cost of the full battery set along with the inverter, not one battery in isolation.
What affects the price of an inverter battery?
Capacity in Ah, the series and design, the backup technology, the warranty and the number of batteries your inverter needs. A higher capacity or a longer warranty generally costs more.
Does a higher Ah battery always give better value?
No. Higher Ah gives more stored energy, but it only helps if your load needs it. Choose the capacity from your appliance load and the backup hours you want.
How many batteries does my inverter need?
A 12V inverter uses one 12V battery, a 24V inverter uses two and a 48V inverter uses four.
What is the difference between SJT and TT batteries?
SJT is the lower design for 110Ah to 160Ah. TT is the taller design for 160Ah to 310Ah. Okaya states SJT batteries recharge about 15% faster than conventional Jumbo Tubular batteries.
What is the warranty on Okaya inverter batteries?
Okaya inverter batteries carry 48 to 66 months of total warranty depending on the model. SJT models carry 48 to 60 months and TT models 48 to 66 months.
What are Certified Backup Hours?
They are backup times Okaya declares at set loads, tested under the UMHD load cycle in NABL-accredited laboratories. They help compare batteries, but real backup varies with load, temperature and battery age.
How often does an Okaya inverter battery need maintenance?
Okaya lists 1 to 2 water top-ups a year on most models. Six ceramic water-level indicators show the electrolyte level, and topping is spill-free.
Where can I check current Okaya inverter battery prices?
Current prices are listed on the Okaya shop. You can also find a dealer through the dealer locator or contact Okaya Care on +91 9818 909090 or care@okaya.in.
For current figures, check the inverter battery price list on the Okaya shop, including the home inverter battery price for 2BHK and 3BHK setups. If you prefer tubular models, the tubular battery price for each capacity is on the same page. To buy in person, use the dealer locator.
