Professional Battery Service at AkkuPlus – More Than Just Cell Replacement
A battery is the heart of many electronic devices. When battery performance declines, the problem is often not limited to the battery cells themselves, but may also involve the control electronics (EEPROM / TI chip).
At AkkuPlus we offer a professional battery repair service that goes far beyond a simple cell replacement. Our goal is to restore your battery's service life, safety, reliability, and full performance.
⚙️ Intelligent Cell Replacement – The Difference That Matters
Many repair providers simply replace worn-out battery cells. However, for modern battery systems, this is often not enough to fully restore the battery's original performance.
Many battery packs contain a Texas Instruments battery management chip (e.g., BQ20Z95) that stores important information such as battery capacity, charge cycles, manufacturing date, and error logs.
At AkkuPlus we do more than replace cells. After the cell replacement process, the battery management electronics are read, analyzed, reset, and reprogrammed to ensure that the battery operates correctly and communicates properly with the device.

Why EEPROM Reprogramming Matters
Even after replacing battery cells, many modern battery systems continue to rely on stored data within the battery management electronics. If this information is outdated or incorrect, battery performance may remain limited despite new cells being installed.
EEPROM analysis and reprogramming allow the battery management system to recognize the new cells and operate with accurate capacity information, resulting in improved performance and more reliable operation.
Repair Instead of Replace
Repairing a battery is often significantly more sustainable and cost-effective than purchasing a new replacement. By reusing housings and electronic components while replacing only worn battery cells, valuable resources can be conserved and electronic waste reduced.
AkkuPlus combines battery repair, battery diagnostics, EEPROM programming, and battery management expertise to maximize the lifespan and performance of your battery packs.

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.
