At present, the following four power batteries can be used by electric bicycles, namely valve-controlled lead-acid maintenance-free battery, colloidal lead-acid battery, nickel-metal hydride battery and lithium ion battery. Today's electric vehicles are mostly equipped with lead-acid batteries, because lead-acid batteries cost low and cost effective. The following points should be noted when buying batteries:
1. Check whether the product logo is complete. Including name of manufacturer, product specification, date of manufacture and trademark; Check whether the internal and external signs are consistent, especially check whether there is a marked mark on the body of electric vehicle battery products, and pay attention to whether the production date is in the near future.
2. Pay attention to the appearance of the battery. Check for deformation, cracks, scratches, and leakage marks. The battery terminal shall be clean and free of rust, and the mark shall be clear.
3. Electric vehicle batteries pay attention to the rated capacity of electric vehicle battery products. The larger the rated capacity marked by the battery, the longer the discharge time of the electric vehicle battery, it is better not to buy the battery not marked by the rating, but should pay attention to whether it is special for electric vehicles, if there are multiple capacity marked, the rated capacity shall prevail.
4. Select well-known enterprises and large enterprises for electric vehicle batteries. The battery is generally provided by the specialized electric vehicle battery factory, the battery quality that different brand, different manufacturer produces has actor bad is different, the price also has the difference of high and low. Well-known, large scale, strong technology, good after-sales service, electric vehicle battery quality assurance.
5. Electric vehicle batteries are selected and equipped with intelligent charger with automatic control. A suitable charger can automatically adjust the charge size and time, which is beneficial to extend the battery life.
