DKOPzV-1000-2V1000AH SEALED MAINTANANCE FREE GEL TUBULAR OPzV GFMJ BATTERY

What are the advantages, disadvantages and uses of tubular and pull lead acid batteries?

Tubular plates have some advantages, such as good deep discharge performance, long battery life, and can be made into larger capacity batteries; However, there are also some fatal disadvantages, such as complex production process (high cost), low energy density (low cost performance), low charging current (slow charging), and large changes in the size of the plate (often breaking the shell).

Compared with tubular plate, grid plate has some disadvantages, such as short life (cycle life and floating charge life are much shorter, because the active material is easy to fall off), limited capacity of battery that can be made (mainly not too high in height), poor performance of small current, etc., but the advantages of current VRLA are very attractive: first, simple process and low cost; Second, it has strong charging capacity with large current and can charge quickly; Third, the energy density is high, which is mainly for tubular plates. In fact, the energy density of lead storage is very low in the battery; Fourth, it is safe. Unless there is impact or high temperature, the shell will not break, because the plate will not change in its life cycle.

With the above characteristics, their respective uses are also obvious: there are two main applications of tubular plates. First, the floating charge life is very long in small current and long-life applications, such as solar energy, wind energy and other clean energy; Second, it can be used with diesel engines in the absence of mains power supply. For example, the communication base station can be used with diesel engines for deep discharge cycle, and the cycle life is quite long; The grid plate is applied to all scenarios except the above scenarios, such as car startup, UPS, communication, electricity, and even power supply for electric vehicles.
