Tubular Plate
A design in which the positive (+) plates are assembled from several tubes in which the active material is quasi "armored".
Thanks to their design they are extremely resilient and cycle resistant and have plenty of space for as much active material as possible (lead dioxide = PbO2).
The more active material there is, the greater the amount of current a battery can supply. This is crucial for the power capability of a battery.
