The Story
The Einhell 4512133 2 x 4.0 Ah 18V Power X-Change Battery & Charger Starter Kit is the ideal way to start or expand your Einhell cordless tool system. This complete kit includes two 18V 4.0 Ah Power X-Change batteries and a high-speed charger, giving users the runtime, power, and flexibility needed for cordless tools around the home, workshop, and garden.
As part of Einhell’s Power X-Change platform, the included batteries are compatible with all Power X-Change cordless tools, helping reduce the need for multiple battery types and chargers. This saves money, improves organization, and provides a more flexible cordless system for users working across multiple applications.
With two 18V batteries included, the kit is also ideal for 36V Twin-Pack tools that require two batteries at the same time. The 4.0 Ah capacity provides extended runtime and sustained power for demanding tasks, making it suitable for higher-performance garden and workshop tools.
Each battery features Einhell’s ABS process-controlled active battery management system, which continuously monitors battery parameters to optimize safety, performance, runtime, and service life. High-quality lithium-ion cells resist memory effect and self-discharge, while the 3-stage LED indicator allows users to quickly check the current charge level.
The included charger uses fast-charge technology to reduce downtime, with a charge time of approximately 75 minutes. Intelligent charge management monitors the battery during charging for safety and efficiency, while a refresh mode can help reactivate deeply discharged batteries. Compact housing and integrated wall-mount eyelets make storage simple and convenient.
Built for everyday cordless productivity, the Einhell 4512133 Starter Kit gives users a reliable power foundation for the full Power X-Change system.
