The 150Ah Tubular Inverter Battery Built for Homes and Offices That Can't Afford to Go Dark
When the grid fails in the middle of a workday or a summer night, the only thing standing between you and a dark, silent home or office is your inverter battery. A weak or undersized battery will give you 45 minutes of flickering backup. The right battery will keep your fans, lights, and television running comfortably for hours without you even noticing the power cut.
The Exide InvaMaster IMST1500 Battery is built for exactly that job. It's a 150Ah short tubular inverter battery engineered with thicker plates, higher electrolyte volume, and deep discharge recovery to deliver reliable, long backup for Indian households and commercial setups.
Palsai is a trusted Exide InvaMaster IMST1500 dealer, supplier, and distributor serving customers across Pune, Goa, and Chhatrapati Sambhaji Nagar, with genuine stock, warranty support, and professional installation.
What Is the Exide InvaMaster IMST1500 Battery?
The Exide InvaMaster IMST1500 is a 150Ah, 12V short tubular inverter battery designed for deep discharge applications. It features thicker tubular plates, 20% more electrolyte per Ampere-Hour, and 1000 charge-discharge cycles at 80% Depth of Discharge backed by a 60-month warranty (36 months full replacement + 24 months pro-rata).
Unlike flat-plate batteries that wear out after repeated deep discharges, the InvaMaster's tubular plate design actively handles the stress of daily charge-discharge cycles. This makes it the go-to choice for areas with frequent or prolonged power cuts, where the battery is expected to deliver full backup regularly, not just occasionally.
Key Features of the Exide InvaMaster IMST1500 Battery
-
Tubular Plate Technology
The InvaMaster uses a robust tubular plate design instead of flat plates. Tubular plates hold their active material better under repeated deep discharges, which is why the battery's cycle life and capacity retention stay strong over years of use. -
Thicker Plates + 20% More Electrolyte
Engineered with thicker plates and 20% more electrolyte per Ampere-Hour compared to standard range batteries. This directly translates into longer life and consistent backup performance even under demanding usage conditions. -
1000 Cycles at 80% Depth of Discharge
Certified for 1000 complete charge-discharge cycles at 80% DOD meaning the battery is designed for daily, deep use over years, not just occasional light backup. -
Deep Discharge Recovery
Recovers reliably even after deep discharges during extended power cuts. This is critical in areas where power cuts run for several hours, leaving the battery significantly depleted before the grid returns. -
Factory-Charged and Ready
Supplied in a factory-charged condition, so it's ready for commissioning the same day you receive it no pre-charging wait time before first use. -
Very Low Maintenance
Requires only minimal periodic water top-up. This makes the InvaMaster IMST1500 practical for homes and offices where regular battery maintenance isn't always convenient. -
Electrolyte Level Indicator
Built-in electrolyte level indicator takes the guesswork out of maintenance, making it easy to check when top-up is actually needed.
