Data-Driven Success: CHISEN Batteries Power 1M+ Scooters Globally

Beyond the Testimonials: What the Numbers Actually Say

In the battery business, claims are cheap. Every manufacturer claims long cycle life and superior quality. What separates marketing from reality is data — measured, verified, and independently audited performance data.

CHISEN Battery publishes its performance data because we have nothing to hide. Here is what we know from operating in the field with over one million electric scooters powered by CHISEN batteries worldwide.

Global Fleet Performance Data (2022–2024)

CHISEN tracked battery performance across 1.2 million vehicles in 23 countries over a 24-month observation period. Here is what the data shows:

Battery Lifespan by Application

Failure Analysis: What Actually Fails

Of CHISEN batteries returned under warranty (2.1% of total shipped), independent laboratory analysis showed:

• 62%: User damage (overcharging, physical damage, water immersion) — not manufacturing defects
• 23%: Natural end-of-life (capacity below 60% after rated cycle count)
• 11%: Application mismatch (battery undersized for motor power requirements)
• 4%: Manufacturing defect confirmed — full replacement under warranty

This breakdown tells an important story: when CHISEN batteries fail, it’s almost never the battery’s fault.

Cycle Life: The Most Important Metric

Cycle life testing conducted by third-party laboratories (SGS, Bureau Veritas) under standard conditions:

• CHISEN 6-DZF series: 450 cycles at 80% depth of discharge
• CHISEN 6-EVF series: 650 cycles at 80% depth of discharge
• CHISEN 6-DMF series: 580 cycles at 80% depth of discharge

Industry average for equivalent applications: 280–350 cycles.

Geographic Performance Variation

Different climates present different challenges. CHISEN’s data from global deployments:

Hot climates (India, Southeast Asia, Middle East — avg. 35°C):

• CHISEN 6-DMF series: 24-month average lifespan
• Formulation specifically optimized for high-temperature electrolyte stability

Temperate climates (Europe, East Asia — avg. 18°C):

• CHISEN 6-EVF series: 34-month average lifespan
• Standard formulation performs excellently

Cold climates (Northern Europe, Central Asia — avg. 5°C):

• CHISEN 6-DZF series with cold-weather starting optimization: 30-month average
• Special cold-weather charging protocol recommended below 0°C

The 1 Million Milestone

Reaching one million vehicles is a milestone that brings responsibility. Every one of those one million vehicles represents a rider who depends on CHISEN batteries to get home safely. That trust is not taken lightly.

“Data transparency is part of our commitment,” CHISEN’s quality director said. “We share our performance data because our partners deserve to make informed decisions. If our batteries weren’t performing, the data would show that too.”
