Short type pole plate valve controlled lead-acid battery

The utility model relates to a valve controlled lead-acid accumulator with short type pole plates, which comprises an accumulator tank, a pole plate plugging box, a positive pole plate and a negative pole plate, wherein the edges of the positive and the negative pole plates are provided with plastic insulated protective films. Through the skillful reformation to the prior art, the utility model improves the performance of the valve controlled lead-acid accumulator. Because the edges of the pole plates are additionally provided with plastic insulated protective films, the ossibility that the positive and the negative pole plates generate short circuit can be reduced. Because the width of the pole plates is increased relatively, the utility model reduces the internal resistance at the bottom of the pole plates and improves the utilization rate of active material arranged at the bottom of the pole plates. Because the height of the plate is decreased relatively, the utility model reduces the generation of the stratification of the concentration of electrolyte solution in the accumulator tank and solves the problems of easy generation of sulfation at the bottom of the negative pole plate, etc. Accordingly, the utility model not only improves the utilization rate of the active material of the valve controlled lead-acid accumulator to improve the charge acceptance thereof but also extends the cyclical service life.
