Ukoke20V Cordless Power Garden Tools (Grass Trimmer)

Works great however when first put on charge instructions said a red light will appear on charger until charged but instead of this a green light appeared. After leaving it on charge for a couple of hours it was still not working, noticing the pins on battery back didn’t look like was lining up to charger properly I removed cover from battery pack and placed pins in correct place by doing this the battery charged and I am now happy with my purchase.
