- Cold Cranking Amps (CCA): CCA is a measure of the battery’s ability to start an engine in cold weather, making it essential for performance reliability.
- Reserve Capacity (RC): This indicates how long the battery can run on its own power without the engine, which is important for maintaining electrical functions.
- Type of Battery: Different vehicles may require different types of batteries, such as lead-acid, absorbed glass mat (AGM), or lithium-ion, depending on their electrical system and usage.
