Retrofit & Cell Replacement – Sustainable Battery Upgrades
At AkkuPlus, we offer more than traditional battery cell replacement. Our retrofit solutions upgrade your battery pack using modern battery technology, helping to improve performance, reliability, and efficiency.
Retrofit means that we not only replace worn-out battery cells but also modernize your battery system where technically possible. As a result, you benefit from higher capacity, longer service life, and improved battery technology without having to purchase an entirely new device.
Our Services
- ✔ Battery cell replacement for power tool batteries, e-bike batteries, and specialty battery packs
- ✔ Retrofit upgrades for improved performance and efficiency
- ✔ Professional inspection, safety testing, and installation of premium-quality battery cells
Why Choose Retrofit Instead of Replacement?
Retrofitting and battery rebuilding offer a cost-effective and environmentally friendly alternative to replacing an entire battery pack or device. By upgrading existing battery systems, valuable resources are conserved while extending the useful life of your equipment.
Our experienced technicians carefully analyze each battery pack and select suitable high-quality replacement cells to ensure optimal performance and compatibility.

Ein BMS ist die elektronische Schutz- und Steuerungseinheit einer Batterie. Sie überwacht Zellspannung, Strom und Temperatur, greift bei kritischen Werten sofort ein und sorgt so für Sicherheit und eine längere Lebensdauer. Bei Blei-Säure-Batterien lässt sich darauf oft verzichten, bei Lithium-Ionen-Zellen ist ein solches System praktisch zwingend, weil die Chemie sonst schnell irreversibel Schaden nimmt. Ohne diese Kontrolle drohen Kapazitätsverlust, Überhitzung oder im schlimmsten Fall ein Brand.
Copilot said: A charge cycle describes a complete charge from 0% to 100% and back down again, whether it happens in a single session or is spread across multiple partial charges. How many of these cycles a lithium-ion battery can withstand before noticeable degradation occurs depends less on the cycle count itself and more on factors such as temperature, charging range, and depth of discharge. The industry typically defines the end of battery life, known as End of Life (EoL), at around 80% remaining capacity. In other words, charge cycles are only one piece of the puzzle and do not tell the whole story.
The most reliable method for measuring battery capacity is a controlled constant-current discharge. All other methods provide only estimates or trend indicators rather than true capacity values. In this process, the battery is discharged at a defined current down to its cutoff voltage, and the extracted charge is calculated using the formula: Capacity (Ah) = Current (A) × Time (h) The result is reproducible, compliant with industry standards, and can be directly evaluated as a measure of the battery’s State of Health (SoH).
Wussten Sie, dass in Deutschland jedes Jahr rund 40.000 Tonnen Batterien verbraucht werden? Jede einzelne Batterie enthält wertvolle Rohstoffe wie Zink, Kupfer oder Lithium, die bei falscher Entsorgung verloren gehen und die Umwelt belasten. Wer Batterien richtig entsorgt, schützt nicht nur Böden und Gewässer, sondern sorgt auch dafür, dass wichtige Materialien wieder in den Kreislauf zurückkehren und Ressourcen geschont werden.
