Review on Energup Li-Ion Replacement Battery Pack For Black Decker Versapak VP Series With 2-Port Charger by Timothy Johnson

I bought these for my Versa Pak circular saw and they were great when I first received them. I removed them from the saw for storage and needed them six months later. Of course they needed a charge and I thought nothing of it. I charged them and they did not work. Thinking the charger might be bad since it saw the original charger, I purchased a new one. I let them charge overnight and still nothing. Don't purchase they are not viable for very long at all. I would have been better off buying better instead of being cheap. You get what you pay for!
