Battery AA Flat
battery rechargeable 900ma Ni-Cd sunnybatt flat
It means flattering in this battery without the tip
Its production without a tip or serial and its positive pole polarity is due to the fact that some of the batteries in which they are used are used in two or more batteries, and therefore these batteries should be serially parallel or with the device point The welds are connected to each other, therefore, it is necessary for the batteries to be folded in order to better connect them
Many devices are like this, like many medical-industrial devices, even screwdrivers
