What Is an Inverter Battery?
An inverter battery stores electricity and supplies it to your home through an inverter during a power cut. Unlike a car battery, it is built for slow, deep discharge and repeated charging.
| Type | How it works | Maintenance | Best for |
|---|---|---|---|
| Tubular (flooded lead-acid) | Tubular positive plates, liquid electrolyte | Periodic distilled water top-up | Frequent, long power cuts |
| SMF / VRLA (sealed) | Sealed, valve-regulated design | None | Low-maintenance homes, UPS and solar |
| Lithium (LiFePO4) | Lithium iron phosphate cells | None | Long life, compact space, daily cycling |
The Top 3 Inverter Battery Brands in India, Reviewed

- LiFePO4 lithium ion batteries suit compact, daily-cycling storage.
2. Exide: Long-Established Brand With Tall Tubular Lines
Best for: premium-segment value and long, frequent outages.
Exide is one of India’s oldest battery makers. The InvaMaster IMTT1500 is a 150Ah tall tubular battery with a 60-month warranty, including 36 months of free replacement.
3. Amaron: Calcium-Hybrid Grid Technology
Best for: low-maintenance use.
Amaron’s heat-resistant calcium-hybrid alloy grid reduces water loss and corrosion. The Current AR150TN54 (150Ah) has a 54-month warranty, including 36 months of free replacement.
How the Top 3 Brands Compare
| Factor | Lento | Exide | Amaron |
|---|---|---|---|
| Capacity choice | 50Ah to 320Ah | 150Ah model listed | 150Ah model listed |
| C10 and C20 options | Both | Check per model | Check per model |
| Free replacement | Confirm per model | 36 months | 36 months |
| Standout feature | Range from home to commercial | Established brand | Low water loss |
| Also offers SMF and lithium | Yes | Check per model | Check per model |
C10 vs C20 Rating: Compare Batteries Fairly
| Feature | C10 rating | C20 rating |
|---|---|---|
| Measured over | 10-hour discharge | 20-hour discharge |
| Discharge rate | Higher, closer to heavy real-world use | Lower, suited to light loads |
| Best for | Long outages, commercial spaces, hybrid solar | Fans, lights, TV and router |
| Buying tip | The same Ah number is the more demanding rating | The same Ah number looks bigger on paper |
Key takeaway: A 150Ah C10 battery and a 150Ah C20 battery are not equal. Always compare at the same rating.
How Long Will an Inverter Battery Last During a Power Cut?
Formula: Backup (hours) ≈ (Battery Ah × 12V × usable factor) ÷ Load in watts
| Battery | Load | Usable factor | Approx. backup |
|---|---|---|---|
| 150Ah | 400W | 0.7 | about 3.1 hours |
| 200Ah | 400W | 0.7 | about 4.2 hours |
| 200Ah | 400W | 0.5 (50% depth of discharge) | about 3 hours |
Using only 50% of capacity extends battery life. Real backup also depends on inverter efficiency, battery age and temperature. To size your setup, read which inverter suits a 200Ah battery.
Tubular vs SMF vs Lithium: Which Should You Buy?
| Feature | Tubular | SMF / VRLA | Lithium (LiFePO4) |
|---|---|---|---|
| Upfront cost | Moderate | Moderate to higher | Highest |
| Maintenance | Water top-up needed | None | None |
| Life | Long with care | Moderate | Longest |
| Best for | Long, frequent power cuts | Low-maintenance homes and offices | Daily cycling, small space |
How to Choose the Best Inverter Battery Brand
- Add up your load. List the watts of fans, lights, TV, router and other appliances you run during a cut.
- Pick the capacity. Choose 150Ah for basic loads, and 200Ah or more for a fridge or longer outages.
- Pick the rating. C10 for heavy or commercial use, C20 for light household loads.
- Check inverter compatibility. Match battery voltage and charging profile to your inverter, such as a Lento sine wave inverter.
- Compare warranty splits. Free replacement months matter more than the headline total.
- Check local service support before choosing a brand.
- Buy from an authorised dealer for a genuine product and warranty support.
Inverter Batteries for Solar and Hybrid Systems
Solar and hybrid setups cycle the battery daily, so deep-cycle, higher-capacity batteries work best. Pair them with an off-grid hybrid solar inverter for reliable home backup. For an inverter with the battery built in, see the Lento sine wave inverter with inbuilt lithium battery.
Inverter Battery Maintenance Tips
- Check distilled water every 2 to 3 months, or as the manufacturer advises.
- Keep terminals clean and lightly greased.
- Avoid regular full discharge.
- Keep the battery in a dry, ventilated, shaded place.
- Use an inverter with the correct charging profile.
