The rechargeable lithium ionic battery is much lighter 40 50 than a nicd battery and it wont lose power when it self discharges the creeping capacity loss memory effect is also prevented the low total weight of approx 700 g makes the shears excellent to use the blades work precisely and give a clean cut this prevents the plants from going yellow where they have been cut features light and easy to use rechargeable battery is up to 50 lighter than common batteries thanks t
