Solar Tubular Battery

A solar tubular battery is a type of lead-acid battery designed specifically for solar energy storage. It is known for its durability, deep discharge capacity, and long lifespan, making it a great choice for off-grid and backup solar power systems.
Key Features of Solar Tubular Batteries
✅ Longer Lifespan – 5 to 10 years (compared to flat plate batteries)
✅ Deep Discharge Capability – Can handle 80% Depth of Discharge (DoD)
✅ High Efficiency – Designed for slow and steady charging/discharging
✅ Better Heat Tolerance – Performs well in hot climates
✅ Low Maintenance – Requires occasional distilled water topping-up
Types of Tubular Batteries for Solar Systems
1️⃣ Short Tubular Battery (ST) – Compact in size, suitable for limited space
2️⃣ Tall Tubular Battery (TT) – Larger in size, offers higher capacity and backup time
3️⃣ Inverter Tubular Battery – Specifically designed for home inverters
