Updated: 2026-07-15

Overview

Jinhao Battery is a reputable manufacturer of lead-acid and advanced AGM/gel batteries, catering to industrial and automotive sectors. Known for robust construction and consistent performance, these batteries are designed to withstand demanding environments, including extreme temperatures and frequent cycling. With a focus on reliability, Jinhao batteries are commonly used in backup power systems, renewable energy storage, and electric vehicles. The brand emphasizes R&D to improve energy density and lifespan, making it a preferred choice for B2B buyers seeking cost-effective solutions.

Structure and Working Principle

Jinhao batteries utilize lead-acid chemistry, with variants like AGM and gel electrolytes for spill-proof operation. The AGM design employs fiberglass mats to absorb electrolyte, enhancing safety and vibration resistance, while gel batteries use silica to immobilize the acid, ideal for deep-cycle applications. During discharge, chemical reactions between lead plates and sulfuric acid produce electrical energy. Recharging reverses this process, restoring the battery’s capacity. Jinhao’s sealed designs minimize maintenance, and advanced grids optimize charge acceptance.

Key Features

Jinhao batteries stand out for their high energy efficiency, with some models offering up to 99% charge retention. Their leak-proof construction complies with international safety standards, making them suitable for indoor installations. Additional features include low self-discharge rates (less than 3% per month) and a wide operating temperature range (-20°C to 60°C). Customizable terminals and modular designs facilitate integration into diverse systems.

Application Areas

These batteries are widely deployed in telecommunications infrastructure to power base stations and repeaters. Data centers rely on them for UPS backup, ensuring uninterrupted operations during outages. In the automotive sector, Jinhao batteries start engines and support auxiliary systems in trucks and buses. Off-grid solar installations also benefit from their deep-cycle capabilities, storing energy for prolonged use.

Maintenance and Precautions

Regular voltage checks and clean terminals are essential to prolong battery life. Avoid exposing Jinhao batteries to direct sunlight or humid conditions to prevent corrosion. Overcharging can cause overheating, so use compatible chargers with automatic cutoff. For AGM/gel types, never open sealed valves—this disrupts internal pressure balance and voids warranties.

B2B Procurement Guide

When sourcing Jinhao batteries, verify supplier certifications (e.g., ISO 9001) to ensure authenticity. Bulk orders often attract discounts, but confirm lead times, as custom configurations may require extended production. Compare specifications like ampere-hour (Ah) ratings and cycle life (typically 500–1,200 cycles) against project needs. Partner with distributors offering after-sales support, including recycling programs for expired units.
