Just an update.

I bought a Motolite Excel 2SM nearly two years ago. First year performance esp. the vehicle start up was really good. About 16 months into its use, it started to exhibit a weaker start. I'm trying to get this replaced under warranty. I brought it to two different battery shops. First one, is where I bought the battery from. They say my alternator needs a checkup, which I think is a misdiagnose bec. it is evident that they don't want to honor the warranty. Second shop which sells the "A" brand, is willing to do a test just to disprove the claims of the first shop, as well as to better defend my warranty claims with the first shop.

If I don't get a replacement, goodbye Motolite. I'm buying the other "A" brand. :D
