টিউবুলার ব্যাটারি ও ফ্ল্যাট প্লেট ব্যাটারির পার্থক্য / Flat battery vs Tubular battery

Flat and tubular batteries both are members of the lead-acid battery family. However, in a flat plate battery both positive and negative electrodes of a Flat plate are in shape. But in a tubular battery, negative electrodes are flat plate type and positive electrodes use a frame structure consisting of a series of vertical spines connected to a common bus bar. Each spine is covered by non-conductive tubes filled with a paste of lead oxide active mass.
