Hey, can you tell me the battery size needed for a 2004 Chevy Silverado 2500HD?

The 2004 Chevy Silverado 2500HD comes with a size 34/78 group battery that delivers 800 cold cranking amps. Warning signs that indicate the battery needs replacing include difficulty starting the engine, problems with cranking, and a lack of interior lights or chimes. Other less common symptoms to watch out for are a clicking sound when turning the key, the need to press the gas pedal to start the vehicle, and misfires. Inconsistent charging can lead to issues such as spark plug misfires and problems with the starter solenoid. If the battery is drained or not holding a charge, it could be due to a faulty alternator. A healthy battery may fail over time if the alternator is unable to recharge it properly. In such cases, it is recommended to have the battery tested, recharged, and to replace the alternator if necessary.
