Strimmer with 2 x batteries

One battery is new 06/23, the other is older and has less power.

The device is powered by a high-capacity lithium battery that allows for a long operational time. Equipped with a telescopic handle, the trimmer is highly adjustable to fit different user heights. The cutting line advance system makes sure that the string is always at the proper length for optimal results. The design of the device also guarantees minimal operator effort and maximum comfort. The GLC2500 is perfect for small and medium-sized lawns, gardens, and flower beds.
