The answer is that it really depends on the type of battery you are using. If you are using a lead acid battery, then connecting the negative terminal first will not cause any damage. However, if you are using a lithium ion battery, then connecting the negative terminal first can cause the battery to overheat and possibly catch fire.
The rechargeable lead-acid battery (LAB) has had a considerable role in human life since the first demonstration by G. Planté in 1860 . The simple, ordinary LAB cell has two grid electrodes of lead alloy immersed in a concentrated sulfuric acid electrolyte. Spongy lead wraps the first grid to act as a negative active material (NAM).
Use a multimeter: Set the multimeter to the DC voltage setting. Touch the positive lead to the positive terminal and the negative lead to the negative terminal. Interpret the reading: A healthy, fully charged battery should read between 12.6 to 12.8 volts. Readings below 12.4 volts indicate a discharged battery.
The good performance of a lead-acid battery (LAB) is defined by the good practice in the production. During this entire process, PbO and other additives will be mixed at set conditions in the massing procedure. Consequently, an active material mainly composed of unreacted PbO, lead sulfate crystals, and amorphous species will be obtained. Later, the same
