The Luminous Red Charge RC 18000ST powers your home seamlessly through extended outages with one of India’s most trusted backup power lineups. It combines high-grade spine alloy grids with advanced tubular technology to deliver rapid charging, minimal water topping, and heavy-duty load handling.
Built in a space-saving Short Tubular (ST) design, this 150Ah battery gives you high backup capacity without the taller footprint of a Tall Tubular unit ? ideal for homes with compact battery trolleys or restricted storage height, without compromising on load handling.
Key Features
Advanced Tubular Plate Engineering: Robust thick-plate structure withstands deep cyclical discharges for steady power during long, frequent outages.
Optimized Spine Alloy Composition: Low-antimony alloy mixture minimizes internal grid corrosion, extending battery lifespan and stabilizing performance in extreme heat.
Fast Charge Acceptance: Recharges rapidly between successive power failures ? ideal for regions with frequent back-to-back outages.
Low Maintenance Design: Highly visible microporous ceramic disc float indicators let you check distilled water levels at a glance while preventing harmful acid fumes from escaping.
Compact Short Tubular Footprint: Delivers 150Ah of backup capacity in a low-height form factor that fits sleek cabinets and space-constrained battery trolleys.

Is This the Right Battery for You?
Who the RC 18000ST is built for
Higher Capacity, Compact Space: Best if you need 150Ah of backup capacity for heavier appliances (mixer grinder, personal cooler) but have strict physical space limitations or a compact, low-height battery trolley.
Frequent Short Outages: Fast charge acceptance makes it well suited to areas with back-to-back power cuts, since it recharges quickly between failures.
Standard Storage Height: If you don’t have the vertical clearance for a Tall Tubular battery, this Short Tubular design delivers the same 150Ah capacity in a lower-profile case.
