However, it also has disadvantages such as low specific energy, limited service life and the need for regular maintenance. Lead-acid batteries are commonly used in automobile starting, electric bicycles and other fields. After the lead-acid battery is produced, it is necessary to use a battery plastic shell detection device to detect the safety of the lead-acid battery plastic shell.

[0003] Battery plastic case is a plastic shell used to contain and protect lead-acid batteries or other types of batteries.

Therefore, a battery plastic shell heat resistance detection device is proposed to address the above problems. Utility Model Content
