How to Identify Battery Quality
1 Answers
There are several main methods to identify the quality of an electric vehicle battery: 1. Check whether the outer packaging is damaged or has been opened: When purchasing a battery, users should first check whether the outer packaging of the electric vehicle battery is damaged or shows signs of being opened. 2. Inspect the appearance of the battery itself: Open the packaging and examine the battery's appearance to see if there are any scratches or abrasions on the surface. 3. Check for rust on the metal terminals of the positive and negative electrodes: Look for anti-counterfeiting marks on the battery. If any of these criteria are not met, it is likely a refurbished battery or one that does not meet quality standards.
