VRLA (Valve-Regulated Lead-Acid) batteries, often called “maintenance-free” or “dry” batteries, are sealed lead-acid batteries that use immobilized electrolytes (gel or AGM technology). They are widely used in UPS, solar systems, and backup power applications in Pakistan.
📌 Key Features of VRLA Batteries
✅ Maintenance-Free – No water refilling needed.
✅ Spill-Proof & Safe – Can be installed sideways (unlike flooded batteries).
✅ Low Self-Discharge – Holds charge longer when unused.
✅ Deep Cycle Capability – Good for solar/inverter use (limited cycles).
✅ Affordable – Cheaper than lithium-ion but less efficient.
🔧 Types of VRLA Batteries
-
AGM (Absorbent Glass Mat)
-
Faster charging
-
Better for high-power applications (e.g., UPS)
-
Example: Eastman Xplorer, Fiamm Sonik
-
-
Gel Batteries
-
Deeper discharge tolerance
-
Longer lifespan (if maintained properly)
-
Example: Trojan Solar Gel, Exide Gel

💰 VRLA Battery Price in Pakistan (2024)
| Capacity | AGM Price (PKR) | Gel Price (PKR) |
|---|---|---|
| 100Ah | 35,000 – 45,000 | 40,000 – 55,000 |
| 150Ah | 50,000 – 65,000 | 60,000 – 75,000 |
| 200Ah | 70,000 – 90,000 | 85,000 – 110,000 |
(Prices vary by brand and warranty.)
⚡ Best Applications in Pakistan
-
Home UPS/Inverters (Eastman, Fiamm)
-
Solar Systems (Trojan, Exide)
-
Commercial Backup Power (Deka, CSB)
-
Telecom Towers (Long-duration backup)
⚠️ Limitations
❌ Shorter Lifespan (3-5 years vs. lithium’s 10+ years).
❌ Sensitive to Overcharging – Requires a proper charge controller.
❌ Lower DoD (Depth of Discharge) – Only 50-60% recommended (vs. 80-90% for lithium).
🔋 VRLA vs. Flooded vs. Lithium-Ion
| Feature | VRLA (AGM/Gel) | Flooded Lead-Acid | Lithium-Ion |
|---|---|---|---|
| Maintenance | Zero | High (water refill) | Zero |
| Lifespan | 3-5 years | 2-4 years | 8-10 years |
| Efficiency | 80-85% | 70-75% | 95-98% |
| Cost (100Ah) | PKR 35K-55K | PKR 25K-40K | PKR 150K+ |
🔧 Maintenance Tips
-
Avoid Overcharging – Use a voltage-regulated charger (13.8V-14.4V for 12V batteries).
-
Keep Cool – High temperatures reduce lifespan.
-
Recharge Immediately – Never leave discharged for long.
-
Clean Terminals – Prevent corrosion with petroleum jelly.
