While high-voltage lithium-ion systems dominate discussion in the EV sector, conventional 12v lead-acid starter batteries continue to play a vital role in vehicle operation.

Still, the AGM battery is just a battery with different chemistry and should not affect the radio operation. I would start by rechecking the installation and cleaning and tightening the connections.

A flooded lead-acid or VRLA battery might be a good option if you have an older car. On the other hand, some newer vehicles require AGM batteries and might not be suited for regular VRLA or lead ...

Tesla replaced the lead-acid low-voltage battery in its vehicles with a Li-ion counterpart in 2021. However, these batteries used NMC chemistry, thus having a higher voltage of 16 volts.

A fully charged lead-acid car battery will have an electrolyte solution of about 37% sulfuric acid and 63% water. In this state, the positive plates inside the battery turn to lead oxide, while ...
