Product Description

The Luminous Red Charge RC 18000TT 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 Tall Tubular technology to deliver rapid charging, minimal water topping, and heavy-duty load handling.

Built in a high-density Tall Tubular (TT) design, this battery carries a larger volume of acid above the plates than compact short-tubular alternatives, giving it superior thermal management and better endurance — making it the right choice for dedicated inverter rooms and homes with ample vertical storage space.

Technical Specifications

Is the RC 18000TT Right for You?

FAQs

1) What makes Tall Tubular (TT) different from Short Tubular battery designs?

The primary difference lies in physical shape and acid volume distribution. Tall Tubular batteries like the RC 18000TT are taller and narrower, containing a larger volume of acid above the plates. This provides superior thermal management, slower water evaporation, and better endurance during long, continuous power outages compared to shorter, more compact designs.

2) Can I use this 150Ah battery with an inverter that previously ran on a lower-capacity battery?

Yes, absolutely. This battery operates on standard 12V DC architecture. Upgrading to a 150Ah battery simply means your inverter will deliver a longer backup duration for the exact same connected electrical load — just ensure your existing inverter supports a 12V single-battery setup.

3) How much backup time will the RC 18000TT provide for my home?

Backup time directly depends on the total wattage of your running appliances. On a typical load of 3 Fans, 3 LED Bulbs, and 1 LED TV (approx. 300W–350W), the RC 18000TT (150Ah) provides roughly 4.5 to 5 hours of continuous backup.

4) What does the 36-month warranty on the RC 18000TT actually cover?

The RC 18000TT carries a 36-month warranty cycle, split as 18 months free replacement followed by 18 months on a pro-rata basis. Free replacement covers manufacturing defects at no cost in the first half of the term, while the pro-rata period offers a proportional discount toward a replacement unit if the battery fails afterward.

5) How often does this Red Charge tubular battery require distilled water topping?

Thanks to the high-quality spine alloy composition that reduces water loss, this battery typically requires water topping only once every 3 to 6 months, depending on your local climate and usage frequency. Monitor the 6 red-and-green float indicators on top of the battery; when the green indicator dips toward the red line, it's time to top up with pure distilled water.
