Deep Cycle Batteries vs AGM: Choosing Your Right Power Solution

Understanding the differences between AGM and Deep Cycle batteries is crucial for making an informed decision. Each type offers unique advantages for specific applications, from UPS systems to renewable energy solutions.

AGM Batteries

Design

Uses fiberglass mat to absorb electrolyte, ensuring spill-proof and vibration-resistant operation.

Performance

Excellent for high-discharge applications, with quick and efficient charging capabilities.

Lifespan

Several hundred to thousand cycles, ideal for moderate use scenarios.

Deep Cycle Batteries

Design

Built for repeated deep discharges with robust construction to handle extensive use.

Performance

Optimized for continuous power supply with careful charging requirements.

Lifespan

Thousands of cycles, perfect for long-term renewable energy applications.

BPDC Series- Deep Cycle Battery

BPDC series is a valve-regulated AGM technology-based battery specifically designed for high-cycling applications. With a higher tin content, a special thick plate structure, and a unique paste formulation it provides a much longer cycle life compared to general-purpose AGM batteries in cyclic applications such as mobility / electric vehicles, renewable energy, recreational vehicles, and marine applications.

Comprehensive Quality Control Process

Our commitment to excellence is reflected in our rigorous steps quality control system, ensuring every product meets the highest industry standards.

1.Plate thickness variations can lead to uneven current distribution. The selection should be based on the specific application requirements and usage patterns of the battery. Thicker plates: better for deep cycle, better resistance to grid corrosion and active material shedding. Thinner plates: Better for high-rate discharge, faster charging

2.Short Circuit Testing is an important quality control measure in the manufactuering process. It is a 100% test for every single battery. There are many reasons that lead to battery short cirbuit: separator defects, plate misalignment, poor welding connections, material impurities, grid defects. It prevents catastrophic battery failures, reduces risk of thermal runaway in advance

3.Air-tightness testing is critical for ensuring battery quality and performance. It involves pressurizing the battery and monitoring pressure retention over time. A properly sealed battery prevents electrolyte leakage, maintains internal pressure, and ensures optimal chemical reactions

4.Weight inspection is another measure that helps us detect that whether the performance meet customers' requirement, Even the specification of the same model varies according to different market, application and the price acceptance of end user. Any significant weight deviation may indicate manufacturing issues requiring immediate attention, making this simple yet effective test essential for quality assurance

5.This multi-functional test reveals: actual capacity verification, charging efficiency, internal resistance characteristics, cycle life performance.The results help identify manufacturing defects, predict battery lifespan, and ensure product quality. Through controlled charging and discharging cycles, we can validate if batteries meet specifications and customer requirements. This testing is crucial for maintaining high product standards and reliability in real-world applications.

6.Refering to the battery distributors and wholesalers, they usually do not have the professional testing euipment like battery manufacturers. The battery system tester offers valuable benefits: Quick and accurate voltage readings, Instant internal resistance measurement, Real-time state of charge indication, Minimal training required for operation. We will also use this tool to unify testing criteria with customers.

Handing Instruction

  • Do not short the terminals.
  • Do not place the battery near or in fires.
  • Do not use the battery in a container or bag without proper ventilation.
  • Operate at a temperature between -15°C to 50°C. But for cycle use, the 5°C to 35°C temperature range is recommended.
  • To properly store the battery, remove battery from equipment or charge and store in a dry and cool place.
  • Immediately recharge after discharging.
  • If sulfuric acid from the battery is spilled on skin or clothing, wash immediately with water. If acid comes in contact with eyes, flush with large amounts of water and immediately see a doctor.
  • To obtain maximum life, the ripple current at the RMS forward current of the charger should be regulated to 10% less than its output value.
  • Avoid mixed use of batteries. Different capacities, histories, or manufacturers of batteries may cause damage to the batteries or other equipment’s.
