Star Plus Platinum is designed for extreme backup performance, faster recharge, and long-lasting durability. This 250Ah Tubular Battery offers the highest power backup facility in the market. 

Expect 60 Months (5 Years) of superior power backup performance with pure, thick tubular battery plates in use. Thick plates can withstand heavy loads and give heavy-duty power backup for every electronic application. 

Nigerian Meteorological Agency (NiMet) presented a Report in February 2026, predicting prolonged dry spells and a warmer climate across Nigerian regions this year. With the prediction of heat waves and dry months, a long-lasting power backup is needed. Here’s how our 250Ah can power for a longer time: 

• High Temperature Electrolyte Formula: Reduces heat-related damage and slows internal corrosion, improving durability in hot conditions.

• Fast Recharge Capability: 6-7 hours of fast recharge capacity minimises time spent in a low-charge state, reducing sulfation and preserving battery health.
• Deep Discharge Recovery: Helps restore performance after heavy discharge, extending usable life over repeated cycles. 

How many solar panels are needed to charge a 250Ah Tubular Battery? 

Thinking of going solar? Best decision for both economic and environmental sustainability. But before choosing any solar setup, know how many solar panels it takes to charge our 250Ah tubular battery. 

To charge a 12V 250Ah tubular battery, you typically need 600-750W of solar panels, which equates to two 350W–375W panels or three 250W panels. A 12V 250Ah battery holds roughly 3,000Wh, requiring high wattage to charge in 4-6 hours of peak sunlight fully.   

What is the backup time of a 250Ah tubular battery? 

Power backup in an inverter battery is the duration (in hours) a battery can sustain your connected electrical appliances during a power grid outage. 

Not every Nigerian region gets the same power grid supply. That’s when long-lasting power backup is required. Our 250Ah tubular battery offers a continuous 7 hours of power backup for homes and businesses alike. 

Universal Inverter Capacity of our Star Plus Platinum enables it to provide power backup easily and seamlessly for any user. Whether it’s a solar, hybrid, or conventional inverter, 7 hours of power backup is guaranteed in every setting. 

How does the Star Plus Load Calculator work? 

Many of our users want to know how much load a tubular battery can take. We have a smart solution for you. Try our Load Calculator for a quick understanding of tubular battery capacity and the associated power backup system. 

Get the estimated backup time, number of solar panels required, if you are thinking of going solar, and the recommended inverter model for a seamless power backup. This can help you understand the power backup system you need and plan your load accordingly. 

5 Ways to Make Your Battery Last Longer 

Batteries are the most critical and costly part of a solar system, so proper care is essential to ensure long service life. Follow these key practices:

• Do not mix old and new batteries: Batteries of different ages perform differently, leading to imbalance and reduced overall efficiency and lifespan.
• Ensure tight connections: Loose terminals can cause resistance, heat buildup, and even safety risks. Regularly check and secure all connections.
• Avoid deep discharge: Do not let the battery drain completely. Recharging before reaching very low levels helps preserve capacity and cycle life.
• Maintain proper airflow: Keep batteries in a cool, well-ventilated space to prevent overheating during charging and discharging.
• Ensure proper charging voltage: Low or unstable input power prevents full charging, leading to long-term performance loss and sulphation issues.
