When your solar installer hands you a quotation with a “150Ah battery” line next to another line for a lithium pack, you face a comparison that is genuinely difficult without a common framework. These are not just different prices, they are different chemistries, different lifespans, different backup capabilities. EPCs preparing these quotes with a cost estimation tool should present both options in usable-kWh terms, not raw sticker price, to avoid this exact confusion.
This guide builds that framework. It provides complete price tables by chemistry, capacity, and brand, and includes backup time calculations for typical Indian household loads so you can compare options on equal footing.
Direct answer. Battery prices cannot be summarised in one range. Dated listings on 14 October 2026 include 150 Ah tubular VRLA at ₹16,760 (Amaron AM150TT42) and ₹17,999 (Luminous LPTT 12150H), and lithium at ₹1,08,000 (Loom Solar CAML-10051, 5.12 kWh by title) and ₹1,23,000 (Deye SE-F5 PLUS, 5.12 kWh). Use the Total Ownership Cost per kWh Delivered framework to compare packs: battery cost ÷ (usable kWh × cycle life at your operating temperature).
Solar Battery Price Table: VRLA (Lead-Acid)
VRLA (Valve-Regulated Lead-Acid) batteries are the legacy storage technology used in UPS and solar backup systems across India. They are available from every electronics shop, carry familiar brand names, and are easy to replace locally.
| Battery | Capacity | Usable energy (50% DoD) | Listing price | Printed warranty |
|---|---|---|---|---|
| Luminous LPTT 12150H (12 V, 150 Ah tubular) | 1.8kWh total | 0.9kWh usable | ₹17,999 | 72 months |
| Amaron AM150TT42 (12 V, 150 Ah tubular) | 1.8kWh total | 0.9kWh usable | ₹16,760 | 54 months (36 free, 18 pro rata) |
We found no verified dated price for other VRLA sizes or brands, so none are shown.
VRLA limitations in Indian conditions:
- Cycle life: shorter than lithium; check the maker’s printed cycle life at your depth of discharge. At one cycle a day in a power-cut zone, cycle life is used up quickly.
- Heat sensitivity: lead-acid cycle life falls as ambient temperature rises, so check the maker’s temperature derating and keep batteries in a cool room.
- Self-discharge: VRLA loses capacity while idle, so top up batteries that sit unused for months.
- Maintenance: Sealed VRLA is maintenance-free in theory, but periodic equalising charges and capacity checks every 12–18 months are recommended.
Solar Battery Price Table: LiFePO4 (Lithium Iron Phosphate)
| Battery | Capacity | Usable energy (80% DoD) | Listing price | Note |
|---|---|---|---|---|
| Loom Solar CAML-10051 (51.2 V, 100 Ah) | 5.12kWh (page title; technical table says 4.92kWh) | 4.1kWh | ₹1,08,000 | No tax statement; no cycle count printed; 5-year warranty |
| Deye SE-F5 PLUS | 5.12kWh | 4.1kWh | ₹1,23,000 | Indian retailer listing |
We found no verified dated Indian prices for Pylontech, Livguard or other lithium packs, so none are shown.
The Total Ownership Cost per kWh Delivered Framework
Price-per-unit (₹/Ah or ₹/kWh upfront) is the wrong metric for battery comparison. The right metric is total cost per kWh of electricity delivered over the battery’s life:
Applying this formula to Indian conditions (operating temperature ~40°C):
| Battery type | Cost (dated listing) | Usable kWh | Cycles (assumed) | Cost/kWh delivered |
|---|---|---|---|---|
| Tubular VRLA 150Ah 12V (Luminous LPTT 12150H) | ₹17,999 | 0.9kWh | 350 | ₹57/kWh |
| LiFePO4 5.12kWh (Loom Solar CAML-10051) | ₹1,08,000 | 4.1kWh | 4,000 | ₹6.6/kWh |
| LiFePO4 5.12kWh (Deye SE-F5 PLUS) | ₹1,23,000 | 4.1kWh | 4,000 | ₹7.5/kWh |
On these assumed cycle counts the lithium packs are several times cheaper per kWh delivered than the tubular VRLA battery. That is the core economic argument for lithium despite the higher upfront cost, and it only holds if the cycle life you are promised in writing is close to the assumption.
Backup Time Calculations for Indian Homes
Critical load definition (minimum comfort during power cut)
- Refrigerator (200L): 160 W
- Ceiling fans × 3: 225 W
- LED lights × 6: 54 W
- Phone charging: 25 W
- Total critical load: ~464 W (call it 500 W)
Extended comfort load (AC + critical)
- 1-ton inverter AC (steady state): 900 W
- Critical load above: 500 W
- Total extended load: ~1,400 W
| Battery | Usable kWh | Backup hours at 500W | Backup hours at 1,400W |
|---|---|---|---|
| 1 × VRLA 150Ah 12V | 0.9kWh | 1.8 hrs | 0.6 hrs |
| 2 × VRLA 150Ah 12V | 1.8kWh | 3.6 hrs | 1.3 hrs |
| 1 × lithium 2.4kWh (80% DoD) | 1.92kWh | 3.8 hrs | 1.4 hrs |
| 1 × lithium 3.5kWh (80% DoD) | 2.8kWh | 5.6 hrs | 2.0 hrs |
| 2 × lithium 2.4kWh (80% DoD) | 3.84kWh | 7.7 hrs | 2.7 hrs |
| 1 × lithium 2.5kWh (80% DoD) | 2.0kWh | 4.0 hrs | 1.4 hrs |
State-Specific Buying Considerations
- Rajasthan, Gujarat (extreme heat): LiFePO4 strongly preferred over VRLA due to heat tolerance. VRLA cycle life falls with heat, so install batteries indoors in a cool room.
- UP, Bihar, Jharkhand (high outage frequency): A higher daily cycle count means VRLA is used up faster. LiFePO4 is more economical long-term. A 4–6kWh bank covers most daily outage patterns.
- Maharashtra, Karnataka, Tamil Nadu (2–4 hours outage): Either chemistry works. LiFePO4 is the better long-term choice; VRLA is acceptable for budget-constrained buyers.
- Kerala, northeast (lower irradiance, moderate outage): System generation is lower; battery sizing remains the same, but payback may extend slightly.
VRLA vs Lithium: Which to Choose?
| Factor | VRLA | LiFePO4 Lithium |
|---|---|---|
| Upfront cost | Lower per pack (₹16,760 to ₹17,999 for 150Ah tubular listings) | Higher per pack (₹1,08,000 to ₹1,23,000 for 5.12kWh listings) |
| Cycle life | Shorter; read the printed figure | Longer; read the printed figure (the Loom page prints none) |
| Lifespan in India | Shorter; depends on heat and cycling | Longer; depends on heat and cycling |
| Depth of discharge | 50% (safe maximum) | 80% (standard) |
| Maintenance | Annual check recommended | None |
| Heat tolerance | Poorer; falls with temperature | Better; check the maker’s temperature range |
| Weight | Heavier per kWh | Lighter per kWh |
| Total cost over the life | Compute with replacements on your own quotes | Compute with printed cycle life on your own quotes |
| Cost/kWh delivered (assumed cycles) | About ₹57 | About ₹6.6 to ₹7.5 |

Common Mistakes When Buying Solar Batteries
- Comparing Ah ratings across chemistries: A 150Ah VRLA battery at 12V has 1.8kWh total energy with 0.9kWh usable at 50% DoD. A 2.4kWh lithium battery would have 1.92kWh usable at 80% DoD. Comparing “150Ah vs 2.4kWh” at face value is meaningless, always compute usable kWh.
- Ignoring inverter compatibility: A lithium battery requires a hybrid inverter with lithium support and BMS communication. Using a lithium battery with a basic inverter/charger designed for VRLA can damage the battery or the inverter.
- Undersizing for the actual outage pattern: If your area has 4 hours of outage per day, you need significantly more storage than for a 1-hour occasional outage. Use the backup time table above to size correctly.
- Not accounting for temperature derating: Battery Ah specifications are given at 25°C. In hot rooms, check the battery datasheet’s temperature curve and add a design margin.
- Using unrecognised brands without IEC 62619 certification: Any lithium battery installed in a grid-connected solar system in India must comply with IEC 62619 safety standards. Non-certified batteries pose fire risk and may void the inverter warranty. Always ask for the IEC certification certificate before purchase.
- Ignoring DISCOM export limits when sizing storage: Excess battery storage capacity beyond what the inverter can charge and discharge within daily generation cycles adds cost without adding value. Consult the net metering India guide to understand how storage interacts with export credits.
- Buying imported brands without verifying local service: For VRLA, the service network of Exide and Amaron is unmatched. For lithium, verify the distributor’s authorisation and service process before purchasing. See the Exide vs Amaron solar battery comparison for a full breakdown of brand service quality, or purchase through a verified equipment retailer that stands behind the certification. MNRE’s rooftop solar guidelines{target=“_blank” rel=“noopener”} require all storage systems to meet minimum safety certifications, confirm your chosen battery has BIS or IEC 62619 certification before purchase.
