I am going to need a new battery for my 06 Lexus IS350 soon. I had to recently add more distilled water to the OEM battery and in doing so had the battery tested at Autozone and PepBoys. Both said I need a new battery. I noticed I needed to add water so I did and the battery is doing fine, but have a feeling that it will need to be replaced anyway in the very near future. I check out both brands and was wondering which is better. I also looked at Optima, but I don't really need that much power. Thoughts?!
