Delivery to the UK from CN was 5 weeks which was within the time quoted, but not what I have come to expect, but I can't really fault it as it arrived within the specified time. I have tested on multiple 12v car batteries and have found no fault with the charger. You simply plug it in - press the mode button until the led goes to the correct mode you desire - then attach the connectors to the battery, the charger auto senses the battery and begins it 7 stage charging process. The blue LED's flash to indicate which stage the charger is on gradually going static on the completed stages. Charging time varies depending in the state of the battery, the only definite timed process is the recondition, or repair, mode that last 16 hours, I'm not sure how effective this is as I don't have a bad battery to test it on, the worst I had was a battery that over time would always drop to 11v and running repair didn't appear to change that, although its possible that it will hold its voltage for longer, but I'm not going to wait another 6 months to find out before posting here. All in all I'm very satisfied with the charger, and have no question about its ability to charge, I like that the charger alternates between the charging rate in Amps and its Internal Temperature while charging and that on the numerous charge cycles I've put it through it always worked and the internal fan, that draws air in at the bottom and pushes it out through the top, kept the charger nice and cool during charging. All in All a good purchase that I am happy to Recommend A+++

I am very happy with this purchase. My lead acid 75AH battery was totally dead. outputting only 2.5volts but now outputs 12.8volts after 22hours of repair charge and 12 hours of normal charge. I am now repair my motorbike battery too. Thanks a lot.
