Title: Great 12/24V Battery Charger with Repair Function
Content: My 6-year-old Audi Q5 can start OK, because it has a strong starter (has auto start/off) but because of it's low state of charge, that function no longer works. I bought a trickle charger before this one which charged well on a 2019 Corolla that's being driven very little and infrequent but not on my 2018 Audi Q5. That other trickle charger charged my battery from 11.7 to 11.9V. I bought this charger due to it has a separate mode for AGM and Repair because my Audi battery is AGM. FYI, manual says you need to wait at least an hour from the last usage of your battery. So, I first charged it in the AGM mode and the display went from 50% to 100% in only 10 minutes but the voltage only improved to 12V. Yesterday I put it on repair mode, and it took 8 hours to show full. I did not wait for it to turn off by itself. The battery now has improved from 12V to 12.55V; from 50% to 80% capacity on a 6-year-old large AGM battery. I did not bother to remove the power cords due to my bad back and the battery is situated in the trunk all the way behind the backseat. Luckily it does not appear to cause any damage to my car. During the repair mode, I monitored the battery temperature with my laser thermometer; the charger nor the battery did not get warm and stayed in the low 70's. PROS: 1) Has separate AGM and Motorcycle and repair mode. 2) Great LCD lighted display will show the battery level when you hook it up even before you plug in the power cord. It will also show charger temperature, charging current & status, battery voltage & etc. 3) Smart charger has a built-in fan to stay cool and it will alter the charging power with respect to the battery status. It will start out slow and rarely goes to the full 10A, then it will decrease the power when you reached half full then even lower at 75%. Even when it's @100% charged, it will trickle charge to the max then turn itself off (fan off but light still on) and display OFF. 4) Great repair mode that reconditioned my 6 year old AGM battery from 50% to 80% capacity. 5) Very good price; I paid $24 shipped. CONS: 1) Very short cord, you will need an extension cord. But it's no big deal. 2) Per owner's manual, in Motorcycle mode, it will charge battery to full then turn off and turn back on when voltage drops below 12.5V. But does that mean you cannot maintain your battery in the other modes? It also states not to leave the charger unattended over 12 hours. Therefore, I don't think this is a battery maintainer which is fine for me. ................................................................ With this battery charger, I can charge my batteries before and after I go on a vacation and let not my batteries charge level go down too low thus prolongs the life of my batteries. I only had it for a week and so far, I am very happy about this product. I will update if the charger quit or have some problems.

Title: This Battery charger is a good product. meets expectations
Content: This battery Charger initially works as advertised and specified. Too soon To comment on reliability overtime. Smaller and lighter than the older style transformer type chargers. Easy to use status display is good but hard to read in bright sunlight. One star off for the state switch. The fingerprint spot function switch is very small and It works only with bare ungloved fingers. Not a good idea when working around old corroded car batteries. Easy to use, functions as expected, well priced and a good value.

Title: Quick, Easy, and Worked Like a Charm!
Content: My AAA roadside service man recommended that I get this unit to refresh my battery because a whole new battery would be overkill, and this unit worked perfectly. It was delivered the same day via Amazon, was super simple to connect to the battery, and has an auto-shutoff feature that keeps you from overcharging it.

Title: Fantastic Battery Charger
Content: So much to appreciate about this charger. I got this charger to replace a Black & Decker Battery Maintainer that went bad after just one use....This charger is so simple to operate; just select the battery type, ie. Car Battery, Motorcycle Battery, etc, hook it up to the battery, then plug in the AC & it automatically start the 7 stage process. First stage it goes into DSF mode, or Desulfurization, then goes into 6 other charging processes. I really like that it has a meter which you can even use to check the voltage on your battery before plugging into the AC. Then after you plug it in, the meter lets you know its working, whereas the B&D had no meter, so you never really knew it was connected to the battery properly, or even charging. It also lets you know the Voltage as it is charging, then reads "Full" when complete. They do recommend you let it run an additional 1-2 hrs (Floating charge) after it is Full. When Floating is complete, it will read "Off", then when this is done, the meter will go dark. I saw some comments that the instructions were poorly written, by a 3rd world country (then translated poorly to English) & hard to understand...They must have written a new set of instructions by an English speaking person, because I found these instructions Very Well Written & quite easy to comprehend, for this Non Mechanical person. It does take some hours to charge. It took me about 10-12 hrs to fully charge from an almost dead car battery, then about 2 additional hours for the Floating Process at the end. Note: They do recommend that you Do Not let this charger run unattended for more than 12 hours. I was reluctant to use this when I first got it, as I thought it would be somewhat complicated, but it was Super Easy. Get this charger; you will Love it.

Title: Recommend a more expensive product if it’s in your budget, but this works well enough for the price
Content: I wish it was a little more granular in letting you select the settings. But it’s also a generic product. It’s been working well enough for my purposes keeping a 24v RV topped off for the winter so far. I think my batteries like having a little more voltage than this unit provides, as after I’m done running the vehicle the voltage is a bit higher than this unit can get them too. My vehicle also has some safety features that remain active when the main battery disconnect is switched off. So there is a slight draw on the system during charging that may be confusing the unit slightly. All of that aside, it’s still doing its job for the price. If I had a greater budget, I’d have gone with a more expensive unit that would probably handle better. For now this is good enough to keep my batteries from dying.
