HBL Power Systems Ltd Industrial Battery Architecture
HBL Power Systems Ltd is India's leading pioneer in specialized engineered battery solutions for mission-critical applications: telecommunication towers, electrical substations, railway signaling, data center UPS systems, defense, and megawatt solar power plants. Known for exceptional metallurgical purity and zero-maintenance sealed recombination technology, HBL batteries are deployed across heavy industries in Vidarbha.
Unlike standard consumer batteries, claiming warranty on industrial VRLA or 2V cells requires strict adherence to operating parameters, float voltage records, and certified engineering test reports. Orange City Batteries provides the localized diagnostic expertise required to document and resolve HBL warranty cases in Nagpur.
How to Process an HBL Battery Warranty Claim
Industrial warranty validation requires the following 4-step documentation procedure:
Compile commissioning logs and float voltage readings
Gather initial installation commissioning reports, monthly float voltage records, and ambient room temperature logs.
Record serial numbers of defective cells
Document the individual cell serial numbers, batch manufacturing codes, and rack positions of the affected battery block.
Perform internal impedance and load discharge tests
Measure cell internal resistance, open-circuit voltage, and discharge performance using calibrated digital battery analyzers.
Submit claim dossier to HBL authorized channel
Submit the completed technical test report and purchase invoice to Orange City Batteries Nagpur for official factory warranty processing.

| HBL 2V VRLA Industrial Cells | 2V (200Ah – 3000Ah) | 36 – 60 Months | Thermal plants, Grid substations, Switchyards |
| HBL Tubular Gel (OPzV) | 2V / 12V | 36 – 60 Months | Solar microgrids & cyclic backup |
| HBL Pure Lead Thin Plate (PLT) | 12V Front Terminal | 36 Months | Telecom 19-inch racks & fast-charge sites |
| HBL Nickel-Cadmium (Ni-Cd) | 1.2V Pocket / Sintered | 60+ Months | Railways, Aviation, Harsh temperature zones |
Critical Warranty Conditions for Industrial VRLA Cells
HBL Power Systems establishes technical criteria that must be maintained to keep industrial warranties fully valid:
Operating Environment Safeguards
- Temperature Control: Rated service life is specified at 25°C (or 27°C). Operating in uncooled Vidarbha plant rooms exceeding 38°C without temperature-compensated charging accelerates grid corrosion and reduces warranty tenure.
- Float Voltage Calibration: Float charging voltage must be calibrated between 2.23V to 2.27V per cell (for AGM VRLA) to prevent overcharging dry-out or chronic undercharging sulfation.
- Ripple Voltage Limits: AC ripple current on the rectifier output must not exceed 5% of rated battery capacity (5A per 100Ah) to avoid internal overheating.

What types of batteries does HBL Power Systems manufacture?
HBL Power Systems Ltd designs and manufactures heavy-duty industrial batteries, including Valve Regulated Lead Acid (VRLA AGM & Gel), Pure Lead Thin Plate (PLT), Tubular Gel, Nickel-Cadmium (Pocket Plate & Sintered), and specialized solar storage systems.
What documents are required to claim warranty on HBL industrial batteries?
Industrial warranty claims require: 1) The original commercial purchase invoice, 2) The initial commissioning report signed by the installing engineer, 3) Routine float charge and maintenance logs, and 4) A calibrated impedance or load test report identifying the defective cell serials.
What is the standard warranty period for HBL VRLA batteries?
HBL VRLA and solar batteries typically carry manufacturer warranties between 24 and 60 months depending on the specific series, duty cycle, and operating temperature specifications defined in the supply contract.
Does Orange City Batteries assist industrial clients with HBL battery testing in Nagpur?
Yes. Orange City Batteries supports commercial facilities, telecom towers, substation contractors, and solar projects across MIDC Butibori, Hingna, and Kalmeshwar with cell impedance testing, capacity checks, and replacement claim coordination.
Where is the serial number located on HBL battery cells?
On HBL monoblocs and 2V industrial cells, the serial number is permanently heat-stamped or laser-engraved on the upper container rim near the terminal posts and printed on the side specification label.
