How to Replace the Battery of a Mercedes-Benz GLA?

[KiaraLynn]

It is necessary to find an AGM battery with the same specifications as the original vehicle. If the specifications are different, it may cause the engine module to receive insufficient voltage, resulting in the inability to clear the fault warning light. For a power-off replacement, first remove the key from the vehicle and wait for 5 minutes to allow the vehicle to enter sleep mode before proceeding with the replacement. When connecting the battery terminals, connect the positive terminal first, followed by the negative terminal. After installation, you can spray anti-rust protectant or acid-free grease on the battery terminals for protection. Start the vehicle and check if the electrical system is functioning properly.
