bought a DELL old laptop computer battery REFURBISHED......
sounds suspicious since in my 50 + years of electronic business I never heard to refurbish a sealed Li-Ion battery. (regenerate in some cases)
Anyway I received the part, installed in my laptop, waited 24 hours....the battery didn't charge.
Informed IMPACT which sent me a replacement and told me I do NOT need to send back the defective battery. By curiosity I went to the lab and open (remove the plastic cover) and found right away a cell completely corroded an still leaking. !! (so much for the refurbish)
I discarded the battery since there are strict laws about shipping/disposing batteries even more Li-Ion.

I informed Impact of my finding.
Installed the second battery...guess what.... do not work either. No way to charge.
Open the plastic cover and did a individual cell charging and load. Half of the cells are dead and the other half not far behind.

Informed Impact of my finding.
Impact informed me that they will refund the battery cost $19.95 ( not the S&H !) if I send back BOTH defective parts.

Of course since I do not have anymore the first I cannot send it back .....so they gave me a RMA which says the first battery was to be returned too.........to cut short and limit my damages I told to them to keep the $ 19.95 and I will keep the second battery as door stop.
