How many years does a Mercedes-Benz battery last without power?

[VonLouis]

Mercedes-Benz batteries typically last 3-6 years without power. Introduction to automotive batteries: Automotive batteries are an indispensable part of a vehicle. The types of batteries used in cars include traditional lead-acid batteries and maintenance-free batteries. These batteries use lead-calcium alloy grids, which reduce water decomposition during charging and minimize water evaporation. The sealed structure of the battery casing also reduces the release of sulfuric acid gas. Precautions for battery usage: Reduce electrical usage when the engine is off; clean and replace the battery regularly; the vehicle should be used periodically. Even if the car is restricted from use or not in operation, it should not be left unused for extended periods, as this will gradually deplete the battery's charge.
