Rechargeable batteries are further classified into different types:a) Nickel Metal Hydride: These types of car batteries are not expensive and due to their low internal resistance, they produce near-constant voltage until they discharge, which means they have high-energy density.b) Lithium Ion Batteries: They are light-weight and mostly used in consumer electronics. It comes with self-discharging property and has high energy density.c) Lead-acid Batteries: They are the first rechargeable batteries and are cheap.Car Battery Life SpanThe average car battery life is between three to five years. The car battery lifespan depends on a lot of factors.

I purchased a Autocraft Titanium battery from them a year ago. This comes with a 3yr free replacement warranty. I took it to them today because it was dead. They happily came out and tested it, and told me the computer said it had a bad cell. They said before they can replace it they need me to leave it with them for 2hrs so they can charge it and retest it. They gave me a loner battery for the time being. I came back and they tested my battery again. The computer said it had a bad cell. Then they preceeded to tell me that they just changed their return policy on batteries 2 months ago and no longer take batteries back without a original reciept of purchase. First of all they are the only retailers of this particular battery in the entire county. Most reciepts today are thermal and don't last very long before they fade out. It was very obvious that my battery was not very old. This is fraud. I recommend that people find another auto parts store to deal with. I will not be shopping there ever agian.
