Top 10 Inverter Batteries in India: Best Tubular, SMF and Lithium Options for Home Backup
14 October 2026
The top 10 inverter battery brands in India are:
- Lento Battery
- Loom Solar Battery
- Exide InvaMaster IMTT1500
- Luminous Inverlast ILTT 18060
- Amaron Current AR150TN54
- Livguard IT1560STT
- Okaya Hadi OPHT18060
- Eastman EM16060TT
- Genus Hallabol GTT170
- V-Guard VT 160
For most Indian homes, a 150Ah tall tubular inverter battery is the standard choice. A 200Ah battery suits heavier loads or longer power cuts. No single battery is best for everyone, so match capacity, rating and warranty to your own load.
What Is an Inverter Battery?
An inverter battery stores electricity and supplies it to your home through an inverter when the grid fails. Unlike a car battery, it is built for slow, deep discharge and repeated charge cycles. The three main types sold in India are:
| 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 needed | Low-maintenance UPS and solar use |
| Lithium (LiFePO4) | Lithium iron phosphate cells | None needed | Long life, compact space, daily cycling |
Explore the sealed option with a Lento SMF VRLA monoblock battery.

C10 vs C20 Rating: Compare Batteries Fairly
Battery capacity (Ah) depends on how long the discharge test runs.
| 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 | Same Ah number is the more demanding rating | 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.
Lento Tubular Inverter Battery Range at a Glance
| Capacity | C10 model | C20 model | Typical applications |
|---|---|---|---|
| 50Ah | LCTB C10 7000 | LSTB C20 7000 | Home lights, basic appliances |
| 70Ah | LCTB C10 9000 | LSTB C20 9000 | Homes, small offices |
| 100Ah | LSTB C10 12000 | LSTB C20 12000 | Clinics, home backup |
| 150Ah | LSTB C10 16500 | LSTB C20 16500 | Clinics, home backup |
| 200Ah | LSTB C10 22000 | LSTB C20 22000 | Retail, small healthcare centres |
| 250Ah | LSTB C10 27000 | LSTB C20 27000 | Commercial, hybrid solar |
| 300Ah | LSTB C10 32000 | LSTB C20 32000 | Commercial, hybrid solar |
All models are 12V. The C20 range extends further, with 180Ah and 320Ah options. A 150Ah battery weighs about 58 to 60 kg and a 200Ah battery about 61 to 63 kg in the Lento range.
How to Choose the Best Inverter Battery for Your Home
- Add up your load. List the watts of fans, lights, TV, router and other appliances you run during a cut.
- Pick the capacity. 150Ah suits most homes with basic loads. Choose 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. A Lento pure sine wave home inverter is designed for this kind of home backup.
- Compare warranty splits. Look at total months and free replacement months, not just the headline number.
- Plan space and weight. Allow a sturdy, ventilated spot.
- Buy from an authorised dealer for a genuine product and after-sales service.
How Long Will an Inverter Battery Last on a Power Cut?
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. For sizing a 200Ah setup, read inverter capacity for a 200Ah battery.
Energy stored: a 12V 200Ah battery holds 2.4 kWh. A 24V version holds 4.8 kWh and a 48V version 9.6 kWh.
Tubular vs SMF vs Lithium: Which Inverter Battery Is Right for You?
| 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 |
For long-life, maintenance-free storage, see Lento LiFePO4 lithium ion batteries. If you are pairing a lithium battery with an inverter, read which inverter is best for a 200Ah lithium battery.
Inverter Battery for Solar and Hybrid Systems
Solar and hybrid setups cycle the battery daily, so deep-cycle, higher-capacity batteries work best. Higher-capacity C10 tubular batteries and sealed solar hybrid batteries are common choices. Explore the Lento SMF VRLA solar hybrid battery and pair it with a Lento household hybrid solar inverter.
7 Mistakes to Avoid When Buying an Inverter Battery
- Buying only by brand name and ignoring load and capacity.
- Comparing C10 and C20 batteries as if they were equal.
- Reading only the total warranty and missing the free replacement months.
- Using a battery your inverter cannot charge properly.
- Ignoring weight and space.
- Buying from an unauthorised seller, which risks fake products and weak warranty support.
- Skipping maintenance, such as water top-ups and terminal cleaning.
Inverter Battery Maintenance Tips
- Check distilled water levels 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.
