I asked about how they handle the warranty since I hear they do not last long. Here is their reply. They mention to use a battery maintainer. They had them for 236 + 30 shipping.

"Our batteries have a good record of longevity. The biggest thing is to properly maintain them since they are generally in cars that are not used much. Sitting is the worst thing for any battery. You want to keep the charge voltage up while not in use by using a battery maintainer or giving a full charge once a month. The battery should also be disconnected from the car to avoid parasitic draws while in storage. There is a 4 year pro rate warranty. You would call to get a return number and send the battery back direct for inspection. Upon inspection the amount credit is determines by taking the purchase price / 48 months (4 years) and multiplying by the age of the battery. This would be how much credit was used, the remaining would be the credit left towards the replacement.
Thank You
