The advantage of this battery has the following aspects:
1. raw-material utilance height adopts two-way utmost point assembled in series method at the storage battery of model of the same race, can increase the capacity of 20%-30%, greatly reduces cost.
2. resistance was little and even up and down when the assembly method that adopts the two-way utmost point to connect was charged.Top and the bottom are the same during discharge.
3. adopt the storage battery of two-way utmost point assembled in series method, little and even because of discharging and recharging resistance, the little moisture loss of storage battery own, the life-span is long.
4. our purpose is an energy savings, reduces cost, and allows prolong the life of storage battery under the constant prerequisite of cost and promote, and the life-span, constant then cost descended, and the capacity life-span of storage battery improves greatly.
