37、 the battery is packed in soft package, to ensure its good performance, its very important to carefully handle the battery 2.2.1 Soft Aluminium foil The soft aluminum packing foil is very easily damaged by sharp edge parts such as Ni-tabs, pins and needles. Dont strike battery with any sharp edge pa

38、rts Trim your nail or wear glove before taking battery Clean worktable to make sure no any sharp particle 2.2.2 Sealed edge Sealing edge is very flimsy Dont bend or fold sealing edge 2.2.3 Folding edge The folding edge is formed in battery process and has passed all hermetic tests. Dont open or defo

39、rm folding edge 2.2.4 Tabs The battery tabs are not so rigid especially for aluminum tab. Dont bend tab 2.2.5 Mechanical shock Dont fall, hit, bend battery body 2.2.6 Short Short terminals of battery is strictly prohibited, it may damage battery. Caution: Danger of explosion if battery is incorrectl
