  • Battery works. Shipping was insanely fast
Item worked as expected. I did charge the battery before installing it in the car but it probably didnt make that much of a difference. The best part was when purchasing, i had an estimate delivery date of maybe 5-7 days. It was delivered, using a delivery service from the vendor, that day. Not sure if its the case with everyone but was for me and i appreciated it. ... show more
