Fein Battery Regeneration – professional power restoration for your tools
Fein battery regeneration is a professional and cost-effective service designed to restore the original performance of your power tools without purchasing a new battery. Fein, a German brand with a long-standing reputation for precision engineering, produces reliable multitools, drills, and grinders used in workshops and industry. Over time, even premium lithium-ion batteries lose their capacity and efficiency. Our company specializes in the regeneration of Fein batteries, using only top-quality cells from Samsung, LG, and Sanyo to ensure durability, safety, and full compatibility with original chargers and tools.
Why choose Fein battery regeneration
Replacing a Fein battery with a new one can be expensive, while low-cost substitutes often fail to deliver performance or safety. Regeneration offers an alternative that restores the full capacity of your existing battery by replacing worn-out cells with new lithium-ion ones of type 18650 or 21700. The original housing and BMS electronics are preserved, guaranteeing perfect fit and communication with your Fein tools. Every regeneration is performed in a controlled environment using professional spot-welding and diagnostic equipment to ensure the highest standards of reliability and quality.
The regeneration process step by step
Each Fein battery undergoes a complete diagnostic check before the regeneration begins. We measure voltage levels, internal resistance, and BMS condition to identify defective cells. The old cells are removed, and new Samsung, LG, or Sanyo cells are installed. The pack is reassembled using industrial-grade spot welding for strong and secure connections. After assembly, the battery is tested under load to verify its capacity, temperature stability, and power output. Every regenerated unit is labeled with a regeneration date and a quality control number for traceability.
Most orders are completed within just a few business days. Each regenerated Fein battery includes a 12 to 24-month warranty. For convenience, we provide a prepaid shipping label, allowing you to send your battery to our service center quickly and at no cost.
