Excelente batería

Súper contento con el servicio y con el producto

I haven't received it yet.

Great cells

These cells perform better than advertised. I highly recommend them. Best price I could find on them too.

good deal

used these to replace a few cells in Dewalt 20v packs. direct replacement and working well

Maybe three and a half stars if I'm being generous.

The reality is this battery works fine. But it doesn't give off as much energy as I would have thought. I also own a hohmrun battery of the same size. Over time the capacity has degraded some. Basically it doesn't last as long as it used to. But at lasts pretty much as long as this brand new one that I'm reviewing right now. So like I said it works, but I was expecting it to be a little bit more exciting capacity-wise.
