Flex Battery Regeneration – restoring full power to professional tools
Flex battery regeneration is a professional and cost-effective solution designed to restore the original performance and capacity of your power tools without the expense of purchasing new batteries. Flex is a renowned German brand known for its precision, reliability, and innovation in the field of industrial-grade tools such as grinders, polishers, drills, and 18V cordless systems. Over time, lithium-ion batteries naturally lose capacity and runtime. Our specialized service rebuilds and restores Flex batteries using only premium Samsung, LG, and Sanyo cells, ensuring durability, safety, and long-lasting performance.
Why choose Flex battery regeneration
Buying a new original Flex battery can be expensive, and cheap replacements rarely meet professional standards. Regeneration provides a sustainable and affordable alternative. We replace only the worn-out lithium-ion cells, keeping the original housing and BMS electronics intact to maintain full compatibility with your Flex chargers and tools. During the process, we can upgrade the battery with higher-capacity 21700 cells for increased runtime and improved efficiency. Every battery undergoes complete diagnostics and performance testing to ensure reliability comparable to a new one.
The regeneration process – step by step
Each Flex battery received at our workshop is subjected to a detailed inspection. We test voltage levels, internal resistance, and the condition of the BMS circuitry. Once diagnosed, old cells are replaced with new branded lithium-ion cells from Samsung, LG, or Sanyo. Spot-welding technology is used for precise and durable connections that meet professional safety standards. After assembly, every battery is tested under load to verify capacity, voltage stability, and thermal performance. Each unit is labeled with a regeneration date and a unique quality control number.
The entire process is carried out in our professional service center equipped with advanced diagnostic and testing stations. Regeneration typically takes between 2 and 5 business days. We provide a 12–24 month warranty on all regenerated Flex batteries. To make the process even easier, customers receive a prepaid shipping label for convenient and free dispatch of their battery to our facility.
