A 12V inverter battery is the common building block of home backup, but the number of batteries you need depends on your inverter's system voltage, and the capacity depends on your load. Okaya's checked 90Ah, 110Ah, 160Ah and 260Ah product pages list their batteries as 12V. This guide covers what 12V means, how many batteries an inverter needs, how to pick the capacity, and how long a tubular battery is expected to last.
12V is the battery's nominal voltage. Okaya's checked product pages list the 90Ah, 110Ah, 160Ah and 260Ah batteries as 12V, with capacity rated at C20. Confirm the voltage on the product page of the model you choose, since the other capacities were not checked here.
It depends on the inverter's system voltage, which is printed on the inverter or in its manual. A 12V inverter uses one battery, a 24V inverter uses two, and a 48V inverter uses four. Connecting batteries in series raises the voltage, and the Ah capacity stays the same as one battery.
Add up the wattage of the appliances you want to run during a power cut, and use Okaya's inverter power calculator for the estimate. Okaya's suggested capacities are 90Ah for a compact setup, 160Ah for a typical 2BHK, 210Ah for larger homes or longer backup, 260Ah for heavy loads and 310Ah for commercial use. Confirm the nominal voltage on the individual product page before purchase. For the full selection steps, see which inverter battery suits your home power needs.
Okaya declares Certified Backup Hours for its models at defined test loads, tested under the UMHD (Urban Metro Heavy Duty) load cycle in NABL-accredited laboratories and printed on the packaging. For example, the 90Ah model is certified at 3:25 at 200 W and 8:10 at 100 W, and the 160Ah SJT with a 60-month warranty at 8:00 at 200 W and 18:40 at 100 W. Okaya also states that XBD+ gives up to 15 to 20% longer backup than a conventional tubular battery of the same Ah capacity. Real backup varies with temperature, battery age, the inverter used and state of charge.
Okaya's FAQ gives a service life of 4 to 6 years, and Okaya's models carry 48 to 66 months of total warranty, made up of a flat period and a pro-rata period. Most models need only 1 to 2 water top-ups a year, and the water type should follow the product manual or Okaya Care. The factors that shorten or extend life are covered in inverter battery lifespan.
Installation is typically arranged through your Okaya dealer. Do not rewire the battery terminals yourself unless you are trained. Use the dealer locator to find nearby Okaya dealers in your area, or message Okaya Care on WhatsApp at +91 9818 909090 or write to care@okaya.in.
Are Okaya inverter batteries 12V?
Okaya's checked 90Ah, 110Ah, 160Ah and 260Ah product pages list them as 12V. Confirm the voltage on the product page of the model you choose.
How many 12V batteries do I need for my inverter?
One battery for a 12V inverter, two for a 24V inverter and four for a 48V inverter. Check the system voltage on the inverter.
Does connecting batteries in series increase the Ah?
No. Series connection raises the voltage, and the Ah capacity stays the same as a single battery.
Which capacity of 12V battery is right for a typical home?
Okaya suggests around 160Ah for a typical 2BHK, with 90Ah for a compact setup and 210Ah or more for larger homes or longer backup. Add up your wattage to confirm, and check the nominal voltage on the individual product page before purchase.
How long will a 12V inverter battery run my appliances?
It depends on the battery capacity and your load. Okaya declares Certified Backup Hours for its models at defined test loads, so compare the declared runtime at a load close to yours.
How long does a 12V inverter battery last?
Okaya's FAQ gives a service life of 4 to 6 years. Warranty is 48 to 66 months, made up of a flat period and a pro-rata period.
Can I connect a 12V battery to any inverter?
Only if the inverter's system voltage matches the battery arrangement: one battery for 12V, two for 24V, four for 48V. Check the inverter manual or ask your dealer.
