As long as the battery is produced by a regular manufacturer, it is acceptable. Both brands of batteries have their own advantages.
1. Chaowei Battery is the first company to apply graphene technology to batteries, and graphene technology is relatively more mature. In particular, the upgraded version of Chaowei Black Gold battery developed in 2017 has fully achieved technological upgrades based on the first generation of Chaowei Black Gold. The core technology of graphene alloy has been further improved, and a unique "galvanostatic column" structure has been used to improve product performance. More stable and longer service life.
While the patented technology of "graphene alloy" has greatly increased the battery capacity, its frost resistance, load capacity, climbing performance, service life, and battery stability have also been comprehensively improved, and has been favored by the industry. It received unanimous praise both inside and outside.
2. Tianneng Battery also perfectly integrates black gold with batteries, which increases the durability of power batteries, extends their service life, and solves the industry pain points of previous batteries that are not durable, easy to bulge, and afraid of low temperatures. And in order to remind consumers to choose black gold batteries with real materials, the product is named real black gold battery.
How to purchase electric vehicle batteries:
1. Check whether the electric vehicle battery product logo is complete
Including manufacturer name, product specification model, manufacturing date, Trademark; check whether the internal and external marks are consistent, especially check whether the product body has an eye-catching logo and production date.
2. Pay attention to the appearance of the electric vehicle battery
Check for signs of deformation, cracks, scratches and leakage. The battery terminals should be clean, free of rust, and clearly marked.
3. Pay attention to the rated capacity marked on electric vehicle battery products
The larger the rated capacity marked on the battery, the longer the battery discharge time. It is best not to buy batteries without rated markings, but Pay attention to whether it is dedicated to electric vehicles.
4. Choose brand batteries from well-known companies and large enterprises
Batteries are generally provided by professional battery manufacturers. The quality of batteries produced by different brands and manufacturers varies. Prices also vary. Well-known and large enterprises have large scale, strong technology, good after-sales service, and guaranteed battery quality.
5. Choose an intelligent charger with automatic control that matches the battery. A suitable charger can automatically adjust the charging size and time, which will help extend the life of the battery.
