The Einhell 18 V 4.0 Ah Sealed Power X-Change Plus is part of the multifunctional and infinitely combinable Power X-Change battery system from Einhell. The universally applicable Power X-Change batteries supply all cordless tools in the entire product family in the garden and workshop sector with power and endurance. The special feature of the sealed battery? Thanks to its sealed housing, it is protected against water jets and dust in accordance with protection class IP57. Thanks to the integrated short-circuit protection on an extra contact at the battery holder, the sensor system recognises contact with water and switches off the electronics. This ensures that the dried battery can be used again even after complete immersion in water. Its latest-generation lithium-ion cells provide 100 % more power for maximum power in all applications, combined with a 13 % more compact design and 10 % weight reduction. PLUS technology also provides extra power for power-intensive work. The high-quality battery also resists the memory effect and the usual self-discharge for constant, high power. The 18 V 4.0 Ah PXC PLUS is a high-end battery from the Power X-Change family and is also suitable for twin-pack use in 36 V applications. The process-controlled, active battery management system ABS constantly monitors the parameters of the battery with the help of the microprocessor used. This ensures maximum safety, optimum device performance, maximum runtime and maximum service life. The current charge status can be checked using a 3-stage LED display. Due to its design, the housing is resistant to corrosion and mechanical influences. The rubber coating gives the battery high impact protection and a good grip. It can be easily removed from all devices using the recessed grip. Supplied without charger. This is available separately.
