East Penn battery manufacturer

Your list is missing one, East Penn Manufacturing. They make their own labeled batteries, as well as several private label, including for Battery Plus stores under the "Werker" and "Ray-O-Vac" brands. They also own the company that makes the BMW branded batteries, although I believe those are made in a seperate factory.

Their "exact fit" batteries for European cars are very high quality.

Where to buy:

I have their standard Group 49 battery (they also make an AGM version) for over 6 years, and it has never needed water (though I check it every couple years) and when I load tested it last weekend, it tested at 925 CCA! Granted, this is a sample size of one, but I am impressed with their quality. I only paid $93 for it 6 years ago.... I think their current price is more like $140, but worth it.
