Not that there aren't good & poor batteries, but I know that when I was younger, I spent about a year working in a battery factory. We had a few different specs of batteries (based on lead core surface area) that we built in a number of different color cases. Then, you guessed it, we slapped on stickers from just about every battery brand available! I slapped on stickers from Napa, to DieHard, to every Auto Parts store brand you can think of. All the same batteries. Other than the newer Gel-type batteries, my experience working for GBC (General Battery Corp.) tells me that the reason they all look the same, is because they are.
