I beleive the Generics are just that.They may not have the same improvements and extended cutoff that the V4L batteries have.
you made a great choice.
here's the reason why generic batteries from V4L are just fine....V4L doesn't build batteries. They order them with their logo printed on the sides. why would they sell these if the quality is different? i would think they are made side-by-side and just not logoed, so they are a tad cheaper.
the logoed batteries come in more color and LED variations. thats the only difference i can tell.
i placed my order!
