Greenworks G40PSF I have been using this tool for a few garden jobs since September and I can confirm that it's a brilliant product.It does come with battery and charger. It was used for maximum 8 hours in total and the battery was charged maybe 9-10 times. No longer needed. It is very important to make sure there is chain oil in the tank when in use.(not included). The tool has been cleaned. Any questions please feel free to ask. 40V Cordless Pole Chainsawn Pruner Kit with 2Ah Battery and Charger.
