What is a Tubular Battery?
A tubular battery is a type of lead-acid battery with a positive plate enclosed in a tube-like structure, which increases durability and performance. This design allows the battery to handle deep discharge cycles, making it ideal for long power backups.
Advantages of Tubular Batteries:
- Longer Lifespan – Lasts 5-8 years, whereas flat plate batteries last 2-4 years.
- Better Backup Performance – Holds charge longer and provides consistent power supply.
- Handles Frequent Power Cuts – Ideal for areas with long or frequent outages.
- Low Maintenance – Requires less frequent water topping than flat plate batteries.
- High Efficiency – Converts stored energy into usable power more efficiently.
1. Latest Innovations in Tubular Battery Technology
a. Tubular GEL Batteries

2. Tubular Battery vs. Flat Plate Battery – Which One to Choose?
| Feature | Tubular Battery (Recommended) | Flat Plate Battery |
|---|---|---|
| Lifespan | 5-10 years | 2-4 years |
| Backup Duration | Longer backup | Shorter backup |
| Efficiency | 80-85% energy conversion | 70-75% |
| Maintenance | Low water loss, occasional refilling | Needs frequent water topping |
| Best For | Homes, offices, frequent power cuts | Short backup needs |
Verdict: If you need a long-lasting, low-maintenance battery, tubular batteries are the best choice.
3. How to Choose the Best Tubular Battery for Your Inverter
Step 1: Calculate Your Backup Needs
For a 150Ah, 12V battery, running a 500W load: Backup Time = (150 × 12 × 0.8) ÷ 500 = 2.88 hours
Step 2: Select the Right Battery Capacity
| Backup Requirement | Recommended Tubular Battery |
|---|---|
| 1-2 hours backup | 100Ah – 120Ah |
| 3-5 hours backup | 150Ah – 180Ah |
| 6-8 hours backup | 200Ah – 220Ah |
Step 3: Key Features to Look For
- Low Maintenance – Look for GEL or AGM technology
- Fast Charging – Reduces downtime after power cuts
- Longer Cycle Life – Ensures deep discharge protection
- Inverter Compatibility – Supports 12V or 24V inverter systems
