A high-performance inverter battery is one that has tested and declared backup hours at defined loads, recharges between power cuts and needs little upkeep, at a capacity that fits your load. This guide explains what to look for in a best inverter battery for a home or an office, and how Okaya's tubular range, from 90Ah to 310Ah, fits each case.
What should a high-performance inverter battery offer?
Check these five things before you decide:
1. Capacity that matches the wattage you need to run.
2. Declared backup hours at a known load, not just an Ah rating.
3. Recharge that keeps pace with how often power cuts occur.
4. Low upkeep, with easy water-level checks.
5. A warranty and a service network you can reach.
Okaya's inverter batteries are tubular batteries made for inverter backup. The current range has 13 models across 9 capacities: one 90Ah JXT model, four SJT (Super Jumbo Tubular) models across 110Ah, 140Ah and 160Ah capacities, and TT (Tall Tubular) models from 160Ah to 310Ah. Okaya states that XBD+ gives up to 15 to 20% longer backup than a conventional tubular battery of the same Ah capacity.
Add up the wattage of the lights, fans and devices you want to run, then match it to a home inverter battery capacity. Okaya suggests these starting points:
1. 90Ah for compact needs such as a few lights and a fan.
2. 160Ah for a typical 2BHK home.
3. 210Ah for larger homes or longer backup.
4. 260Ah for heavy loads.
5. 310Ah for commercial use such as shops and offices.
The inverter power calculator helps with the wattage. If you also need to pick the inverter, read choosing the right inverter for your home.
Size depends on the container design. Check that the space you have fits it:
1. SJT (110Ah to 160Ah): 540 x 210 x 317 mm.
2. TT (160Ah to 260Ah): 508 x 198 x 404 mm.
3. TT 310Ah: 510 x 215 x 413 mm.
The full list of inverter battery size and weight for each model is on the product listing.
Your inverter's system voltage decides the battery count: one battery for a 12V inverter, two for 24V and four for 48V. When identical batteries are connected in series, the system voltage increases while the Ah rating stays the same. A higher-voltage system therefore needs more space and a larger total battery cost.
Look at the declared figure for your load. Okaya's Certified Backup Hours are tested under the UMHD (Urban Metro Heavy Duty) load cycle in NABL-accredited laboratories and printed on the packaging. Examples, in hours:minutes:
A. 90Ah, 48 months (24+24): 3:25 at 200 W, 8:10 at 100 W.
B. 160Ah TT, 60 months (36+24): 8:45 at 200 W, 20:15 at 100 W.
C. 210Ah TT, 60 months (36+24): 12:05 at 200 W, 28:10 at 100 W.
D. 260Ah TT, 66 months (42+24): 15:05 at 200 W, 32:40 at 100 W.
Real backup varies with temperature, battery age, the inverter used and the battery's state of charge. Okaya states that its SJT batteries recharge about 15% faster than conventional Jumbo Tubular batteries.
Okaya states that most of its models need only 1 to 2 water top-ups a year. Six ceramic water-level indicators let you check the level, and SJT batteries have all water inlets on one side in a 6x1 layout. Use the water specified in the product manual or by Okaya Care for your model.
Total warranty is 48 to 66 months depending on the model, made up of a flat period and a pro-rata period. Warranty registration is paperless, and Okaya lists an all-India onsite service network. Message Okaya Care on WhatsApp at +91 9818 909090, write to care@okaya.in, or use the dealer locator to find nearby Okaya dealers in your area.
It is a battery with tested and declared backup figures at defined loads, suitable recharge performance, low maintenance requirements and a clear warranty.
Which inverter battery is right for a 2BHK home?
Okaya suggests around 160Ah for a typical 2BHK. Add up your wattage to confirm.
Which inverter battery suits an office or shop?
Okaya suggests the 310Ah battery for commercial use such as shops and offices. For smaller loads, use your wattage to pick a lower capacity.
How many batteries does an inverter need?
It depends on the inverter's system voltage: one battery for 12V, two for 24V and four for 48V.
How much backup does a 160Ah tall tubular battery give?
The 160Ah TT with a 60-month warranty is certified at 8:45 at 200 W and 20:15 at 100 W. Real backup varies with temperature, battery age and the inverter used.
How often should I add water to an inverter battery?
Okaya states that most models need only 1 to 2 top-ups a year. Check the water-level indicators and use the water specified in the product manual or by Okaya Care.
What warranty do Okaya inverter batteries have?
Total warranty is 48 to 66 months depending on the model, made up of a flat period and a pro-rata period.
