How about Tianjin Le Tai battery?

1, maintenance-free, valve-controlled sealing technology and adsorption glass fiber partition, no need to add electrolyte during the service life.

2. The sealing structure and sealing technology ensure that the battery has no electrolyte leakage and can be used normally in any position.

3. No memory effect. Some batteries, such as nickel-cadmium batteries, will have a corresponding decline in capacity after many cycles, which is the memory effect, but this kind of battery does not have this performance.

4. Low self-discharge. The battery adopts a special lead-calcium alloy grid, which controls the self-discharge less and does not need to be charged even if it is stored for a long time.

5. Long service life. The grid made of special materials and the electrolyte added by polymer materials greatly extend the service life of this battery. Therefore, Tianjin Le Tai battery is quite good.
