Increased battery discharge when the car is parked means the battery is over-discharging. When the ignition switch is turned on, the dashboard will display a warning indicating battery over-discharge. This is closely related to the car battery. Below are detailed explanations about car batteries: Overview: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. The battery typically refers to a lead-acid battery, which is mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte. Others: The plates of a conventional battery are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low cost; the disadvantages are low specific energy (i.e., the amount of electrical energy stored per kilogram of battery), short service life, and frequent daily maintenance.

Why hasn't the ETC fee been deducted?

Reasons why the ETC fee hasn't been deducted: It is likely an ETC debit card, which records transactions first and deducts fees uniformly at the end of the month on the settlement date. If the fee hasn't been deducted by the end of the month, you can call the bank or ETC customer service for inquiries. ETC credit cards follow a 'consume first, deduct later' model, settling once a month. The ETC center handles the unified settlement, then deducts the amount from the bank credit card account. Once the credit card bill is issued, you can proceed with normal repayment. The purpose of ETC is to allow vehicles to pass through highways quickly, improving road capacity. Electronic toll collection helps enhance vehicle operational efficiency, reduces noise and exhaust emissions at toll booths, and significantly increases traffic capacity.
