Power that never fades
Premium inverter batteries from India’s top brands. Luminous, Microtek, Eastman, Addo, Exide, Livfast, Amaze, Livguard & Lithium — all at unbeatable prices.
Inverter Battery Basics
An inverter battery stores electrical energy to power your appliances during outages. The two main types are Lead Acid (affordable, reliable) and Lithium (longer life, lightweight, fast charging). Choosing the right capacity (Ah) depends on your total load and backup hours.
For a typical Indian home, a 150Ah lead-acid battery provides 2-3 hours of backup for fans, lights, and a TV. For longer backup or sensitive electronics, consider Lithium batteries with deeper discharge capability.

Detailed Comparison
| Parameter | Lithium Battery | Lead Acid Battery |
|---|---|---|
| Cost (Initial) | Higher (₹12,000+) | Lower (₹6,000 – ₹10,000) |
| Lifespan | 8-10 years | 3-5 years |
| Weight (150Ah) | ~25 kg | ~55 kg |
| Charging Time | 1-2 hours | 6-8 hours |
| Maintenance | Zero maintenance | Water topping required |
| Depth of Discharge | 80-90% | 50% (max) |
| Warranty | 5-7 years | 2-3 years |
Which one should you choose?
If you have a higher budget and want long-term savings, Lithium is the future-proof choice. If you are on a tight budget and need a reliable backup for occasional use, Lead Acid is still a great option. InvaTek offers both with expert guidance.

Top 5 Tips to Extend Battery Life
1. Keep terminals clean. 2. Avoid deep discharge below 50%. 3. Ensure proper ventilation. 4. Check water level (for lead acid). 5. Use a smart charger. Following these can add 2-3 years to your battery's life.
Inverter vs Generator – Which is Better?
Inverters are silent, emission-free, and cost-effective for short power cuts. Generators are better for long outages and heavy machinery. For most homes, a reliable inverter with a good battery (like Lithium) is the clear winner.
Understanding Battery Capacity (Ah)
Ah (Ampere-hour) indicates how long your battery can supply power. For a typical home, a 150Ah battery provides 2-3 hours of backup during an outage. Calculate your load (in watts) to choose the right capacity.
Solar Batteries: What You Need to Know
Solar batteries store energy from solar panels. Lithium batteries are preferred for solar due to their high round-trip efficiency and deep discharge capability. InvaTek offers specialised solar batteries for off-grid and hybrid systems.
