Super-fast charge time A Gtech Li-Ion battery will be fully charged & ready to use in just 3 hours. In comparison a Ni Cad battery can take up to 10 hours to fully charge. Zero drop off levels in performance Its frustrating when a battery struggles on for the last 10 minutes of its run time, bringing the performance of your product down with it. Li-Ion batteries however are different, they keep on working at full capacity all the way through their run time, meaning you can keep on cutting your hedge right until the point it runs out of power. Zero discharge levels Left over a long period of time, a Ni Cad battery can loose up to 50% of its charge, frustrating when you want to cut your hedge now. Over the same period of time a Li-Ion battery will only loose about 5% of its charge, meaning it is always going to be ready to use, Lightweight technology Due to the compact nature of Li-Ion technology, Gtech’s British engineers have managed to incorporate a powerful 14.4 V battery pack into the handle of the ST05. This removes the need for a battery pack to be worn on the hip, & so offers levels of user friendliness & flexibility like never before.
