Real User Reviews
Mark T. (California, USA)
“The original battery in my 2015 Leaf lasted 8 years, but the range had dropped to 120km. Replacing it with an OEM battery would cost $16,000! I chose a 62kWh battery from CNS for $7,800. After installation, the full charge range is 430km. I’ve been using it for almost a year, and the battery capacity is still at 11 out of 12 bars.”
Lisa K. (Berlin, Germany)
“After the original battery degraded, the 4S dealership quoted €12,000. My friend recommended CNS. The brand-new CATL battery cells were the same quality as the original. Now, the full charge range has increased from 180km to 290km. The lifetime technical support is incredible!”
Mike’s Auto Service (Vancouver, Canada)
“As a repair shop, we replace EV batteries monthly. CNS is our most reliable supplier. Their batteries have excellent compatibility and cover all Leaf models. The 2-year warranty is longer than other brands. Customer feedback indicates the range meets the stated specifications.”
