Tubular battery vs Flat plate battery | difference between Tubular battery and Flat plate battery
This page compares Tubular battery vs Flat plate battery and mentions difference between Tubular battery and Flat plate battery.
Introduction:
Both are lead acid batteries with different design structures. They have their respective benefits and drawbacks.
Let us discuss them individually before we derive difference between them.
Tubular battery

• The figure-1 depicts structure of tubular battery.
As shown it uses series of tubes which are placed side by side length wise.
Tubular battery grid has comb like structure.
• It uses thicker electrodes.
Hence it produces small currents for long time
period of usage.
• It is used for various applications which include power backup at home and
small offices, solar equipments, electric propulsions etc.
Normal Flat plate battery

• The figure-2 depicts structure of flat plate battery.
Normal battery grid has multiple squares like structure which forms
broad mouthed mesh.
• It uses thinner electrodes. Hence it can produce huge amount of currents in
very short time period of usage.
