I have been having nothing but problems with the batteries in my 2000 viper. I have gone through at least 8 batteries in the last 4 years. The dealer takes it in and performs all the tests but they find nothing wrong. Luckily most of the batteries have been on warranty but I am real tired of having battery problems when I want to use the car.

Has anyone heard of or tried these lithium ion batteries? http://www.reli-ionbatteries.com/automotive/

They have a never die system that turns off the battery so that it never drains completely and enough reserve to get your car started.

I believe they run about three times the price of a regular battery but if they work I think it will be well worth it.
