Introduction
In India’s fast-growing solar landscape, choosing the right battery is just as important as selecting the right solar panels. Tubular solar batteries stand out for their durability, efficiency, and performance—making them the go-to choice for homeowners, businesses, and industries alike. At Activolt, we specialize in supplying, installing, and maintaining premium tubular batteries to optimize your solar energy solutions.
What Are Tubular Solar Batteries?
Tubular batteries are deep-cycle lead-acid batteries with a cylindrical plate design. Unlike traditional flat-plate batteries, tubular batteries feature positive plates nested within metal tubes, ensuring better retention of active material and enhanced durability. They are engineered to handle extensive charge-discharge cycles, making them ideal for solar installations where consistent performance is critical.
Core Benefits
Longer Lifespan & Durability
- Tubular batteries last significantly longer—typically 5–10 years, compared to 3–5 years for flat plates.
- Durable build resists corrosion and degradation in demanding environments.
- Robust performance in extreme weather—excellent thermal tolerance for Indian conditions.
Deep Discharge Capability & Cycle Life
- Engineered for deep-cycle applications, such as solar setups requiring consistent energy draw.
- Handle 800–1,500 charge cycles at 80% depth of discharge—far above flat plate performance (~600–800 cycles).
High Energy Efficiency & Charge Acceptance
- Higher charge acceptance captures solar energy more efficiently, especially during shorter daylight.
- Low self-discharge rates ensure maximum energy storage and utility.
Low Maintenance
- Larger electrolyte volume and tubular design mean less frequent topping up.
- Superior water and acid retention prevents corrosion and prolongs life.
TCO & Environmental Advantages
- While upfront cost is higher, lifecycle cost is lower due to longevity and reduced downtime.
- Sustainable choice—with low environmental impact and recyclable materials .
