Tianneng TNE 12-25 General Deep Cycle 12v 25ah Electric Bicycle Lead Acid Battery

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Deep Cycle Endurance: Designed for repeated deep discharges (down to 50% state of charge) in applications like electric bicycles, solar power systems, and uninterruptible power supplies (UPS). The 25Ah capacity ensures sustained power delivery for demanding tasks.
  • AGM Technology: Sealed, maintenance-free design with non-spillable AGM (Absorbent Glass Mat) construction, enabling reliable operation in varied environments without electrolyte leakage.

Key features

  • 1. AGM Technology for Enhanced Durability

  • With AGM (Absorbent Glass Mat) technology, you can achieve a maintenance-free, spill-proof design that resists corrosion and vibration. This sealed lead-acid battery outperforms traditional flooded batteries by eliminating the need for electrolyte refills and reducing leakage risks*.

  • 2. Sealed Design for Universal Compatibility

  • With a fully sealed structure, you can safely install this battery in compact systems like electric bicycles, golf carts, and solar setups without担心液体泄漏或维护需求. Its non-spillable design ensures reliability in both residential and commercial environments.

  • 3. High-Performance 25Ah Capacity

  • With a 25Ah capacity and 0.5C discharge rate, you can deliver stable power output for prolonged use in electric vehicles, home appliances, and UPS systems. This balances energy density with rapid discharge capability for demanding applications.

  • 4. Deep Cycle Endurance for Frequent Use

  • Designed for deep cycling, this battery allows repeated discharges to low charge levels without capacity loss. Ideal for solar storage, electric wheelchairs, and power tools, it maintains performance over thousands of cycles compared to standard car batteries*.

  • 5. UL-Certified Safety and Quality

  • With UL certification, you can trust compliance with global safety standards for fire resistance and electrical performance. This ensures reliable operation in critical systems like emergency lighting and medical equipment.
