Do cheap automotive batteries last as long more expensive batteries?

Generally, no. Cheap automotive batteries tend to have shorter lifespans compared to more expensive batteries.

Quality of Materials:

- Cheaper batteries often use lower-quality materials in their construction leading to faster degradation

Construction and Durability:

- More expensive batteries tend to have robust construction using thicker plates, enhanced grids, and improved electrolyte composition making them more durable.

Reserves, Capacity, and CCA (Cold Cranking Amps):

- Higher price batteries often offer greater reserve capacity and higher CCA allowing for longer performance and reliable starting even in difficult conditions.

While a cheap battery might save money upfront, it may require you to make repairs such as more frequent replacements within a shorter period leading to higher cumulative costs in the long run.
