Single-cell replacement: did you know?
86% of batteries can be safely repaired through mechanical component maintenance, without the need for single-cell replacement.
STUDY (January 2026): 86% of micro-mobility battery failures processed by NOWOS are related to structural (70%) or electronic components (16%).
An analysis of 240.000 diagnostics and repairs performed on batteries sent to NOWOS since 2020 reveals that 86% of micro-mobility battery failures are related to structural (70%) or electronic components (16%), such as casing damage and software locks, rather than the cells themselves.
From the 14% unrepaired batteries, the majority have problems with the complete cell pack. A small percentage has individual cell problems. By replacing only one cell module, though, the other cell modules will often fail due to corrosion.
→ These findings suggest that the majority of batteries can be safely repaired, without the need for single-cell replacement, provided the industry prioritizes accessibility and high-quality design.
HOW WE WORK
-
We first assess any documentation you have such as the UN 38.3, MSDS, any technical sheets
-
With a sample of 5-10 batteries, chargers and tooling we perform a physical repairabiity test on batteries. We look at the time it takes to dismantle and reassemble, availability of spare parts, skills required.
This allows us to provide a repair quote.
-
We discuss together the potential volume of batteries in need of repair on a monthly and/or yearly basis.
-
After agreeing on a Statement of Work outlining all the requirements, we start a pilot batch of repairs and prepare for the next flows.
