Battery Basics

A lead-acid battery stores electrical energy through a chemical reaction between lead plates and electrolyte solution. During discharge, chemical energy converts to electrical energy, and the process reverses during charging.

Capacity in Ampere-hours (Ah) indicates how much charge a battery can store and deliver over time. Higher Ah means longer backup under similar load conditions.

Price differences arise from plate design, material quality, manufacturing processes, warranty coverage, and brand reliability.

VRLA (Valve Regulated Lead Acid) batteries are sealed, maintenance-free batteries designed to prevent electrolyte leakage and reduce water loss.

In a dry-charge battery, plates are pre-charged and dried before assembly. Electrolyte is added before first use, followed by an initial boost charge.

Usage & Maintenance

Water level should be checked periodically and topped up with distilled water when it drops below recommended level.

Maintain proper charging, avoid deep discharge, keep terminals clean, and follow regular maintenance guidelines.

Low temperatures reduce chemical activity, temporarily lowering battery capacity and starting power.

Solar batteries store excess solar energy for later use, reduce dependence on grid power, and provide backup during outages.

Lithium Battery

Lithium batteries are lighter, charge faster, and typically offer longer cycle life compared to lead-acid batteries. Lead-acid batteries are a reliable tested technology which are more economical upfront but require regular maintenance.

Battery life depends on usage patterns, charging practices, and operating conditions. Under normal conditions, lithium batteries generally provide significantly higher charge–discharge cycles than conventional lead-acid batteries.

Yes. Lithium batteries require compatible lithium chargers with proper voltage control and safety protections. Using an incorrect charger may affect performance or safety.

Compatibility depends on vehicle design, controller specifications, and charging system. Consultation with an authorized technician or dealer is recommended before conversion.

Solar & Energy Solutions

PM Surya Ghar: Muft Bijli Yojna is a Government of India initiative that promotes rooftop solar installation for households by providing financial assistance and encouraging clean energy adoption. Scheme benefits and eligibility are defined by government guidelines and may change over time.

Applications are typically submitted through the official government solar portal or approved local agencies. Users should verify current procedures through official government sources or authorized solar installers.

  • On-grid systems are connected to the utility grid and can export excess electricity.
  • Off-grid systems operate independently using batteries to store energy for backup and usage during non-sunlight hours.

On-grid systems may operate without batteries, while off-grid or hybrid systems require batteries to store energy for backup power.

Key factors include energy consumption, backup requirement, installation space, sunlight availability, system capacity, and compatibility with inverters and panels.

Warranty & Service

Warranty duration varies by product category and covers manufacturing defects under normal usage conditions.

Visit an authorized dealer or service partner with the original invoice and product details for inspection and support.

No. Warranty does not cover damage due to mishandling, improper installation, or misuse.

Recycling & Safety

They must be handled responsibly due to lead and acid content, but are safe when used and recycled properly.

Return used batteries to authorized dealers or recycling partners to ensure safe and compliant disposal.

Orders, Shipping & Returns (E-commerce)

Orders can be placed through authorized channels or online platforms where available.

Approved digital payment methods and banking channels are supported depending on purchase mode.

Delivery timelines vary by location and product availability.

Installed batteries are non-returnable. Replacement is provided only for verified manufacturing defects under warranty terms.
