I bougth this charger I really like it .

Useless for my particular situation ! Let me explain. I had only 3 hours time to charge Fully my Ford Escape 2013 battery. The battery was not empty but low 12.0 v (engine not running ,no lights on or radio on) I connected this charger and selected the acid lead battery type and set for 30A ,then I press START. The charger started ok showing pulses from Zero A to 30 A every second or so. I thought all is ok but 30 min later the voltage on the car battery went from 12.0 v to 12.2 v. I would not believe my eyes ; way to low.I discontinued everything and connect my old CENTURY 10 A (auto/manual)CHARGER. THE voltage on the battery went to 13.5 v in15min !! Then I understand the difference, The first charger is. Ot a conti uous charger but uses pulses that go to 30 A but it switched off in one second to start again ,it will take days to bring my 12v battery to a fully charged state. My old Century charger pushes 10 Amp Continuosly into the battery thus the charging is much faster. I am not saying that the pulse 30 A is useless, it is a great charger but was not for my particular need( when I wanted a fast continuously 10 Amp charging. Of course I know that I have to keep an eye on the battery voltage and disconnect it when fully charged Or I can switch this nice Century auto.atic/ manual 10 A charger on Auto so it will stop automatically when the battery is 90% full. I like to keep it on Manual because I get the full 10 A due to li.ited time I have (2 hours)

Love this product, works as described

The charger instructions are lacking many details. I followed the instructions exactly and the charger just flashes information on the screen, and nothing else. Press the start button, you see the information flash and then nothing happens. It just sits there flashing the information. I connected an old battery and also a brand new battery to see if the charger did anything different, but No Difference!! Contacting the manufacturer is useless. They ask questions, but give zero answers. You basically work for them to figure it out and waste your time, not to mention the time delay to get any response at all. Item RETURNED!!!!! Sounds like a great product but NOT.

I have four battery chargers already, so why did I get another one? The oldest one is a simple transformer from the 1960s that will apply a charge no matter what the battery voltage is. I use it to get a charge started before switching over to one of the self-regulating chargers. The second oldest one is from the 1970s, and it still works. The third oldest one is from the early 2000s, and it still works. The latter two are heavy transformer types with very limited charging modes and display feedback. The fourth is a 1-amp NOCO Genius that is pretty good. I got this battery charger in addition to my others because it has more modes for a variety of battery types. There's also a "repair" mode. I've seen lots of YouTube videos of people restoring old batteries. Sometimes it works. However, the idea of charging with a welder to get electrolyte boiling and cooking doesn't appeal to me. I have an old large AGM battery for my house power generator that I have replaced. I still have the old battery sitting around so I thought I'd give it a repair cycle or two. I did not have high hopes. I attached the new charger to do its thing for two repair cycles. Wow, now it's holding a full charge! I attached my load tester and did three test cycles allowing the tester to cool between each cycle. Wow, now it tests OK! After load testing, I now have the charger in normal mode applying a 10-amp load. I will challenge this battery over the next few days, and if it turns out it really didn't work, I will update here. UPDATE: The charger did good work, but the battery resting voltage is now 12.4 volts, which is degraded. The load tests are good, but the resting voltage drooped a volt by the next day. The old battery is just worn out. That said, the charger is still top notch. Otherwise, it works! Oh yeah, I really like the information provided by the display. It's so much better than a simple red/fellow/green LED to indicate the state of the charge. Also, this charger is very lightweight compared to the older designs. There's a much smaller transformer in the new one due to the circuit design. Verdict: Recommended. Amazing!
