NEXPEAK NC201 10-Amp Battery Charger, Smart Trickle Charger 12V 24V Car Battery Charger Fully Automatic Maintainer Desulfator w/Temp Compensation for Car Truck Lawn Mower Boat Marine Batteries

This charger is great! I had to jumpstart my car every time I needed to go anywhere because of lack of use, and I only drive locally, in stop-and-go traffic. I bought this NexPeak after my friend loaned me hers, and it worked great. I decided that I needed one of my own. This charger arrived promptly, and in good condition. I put it on Repair mode, and let it do its thing. Ten hours later it was all done. There is a bit in the instructions which seems to advise letting the charger run past when it says "Full" to when it says "Off", so I did. That was about 4 days ago. Since then I have only driven twice, for about a block and a half each time, and it still starts like a charm. I am so happy with this charger that I bought it a dedicated carry backpack. So glad that I bought this!

I've searched several online and local stores for a 10 amp charger and couldn't even find a lower amperage one that is less expensive. Note, I said "less expensive", not cheaper. works very well. It charged my Jeep AGM battery sometime overnight to 100%. The battery had a very low charge , only enough to power the courtesy lights when door was opened....but "dead" if I tried to start. As recommended by the instructions, I let the charge continue until the FUL message was displayed. My older charger would not charge at 10 amps. The display is bright and easy to read. Just remember to select the battery type and pay attention to the connect and disconnect instructions. Construction, fit and materials look as good a more expensive units I examined. The clips are a bit small, but use an integrated piece of metal to connect to the charger cables. They are not copper, but appear to be steel. If you connect the clips backwards, the display will warn you. Very quiet and cool. This unit was manufactured in China...not my first choice, but check the box, it appears they are manufactured in more than one country.

Didn't know how good this would be considering it's small size and a Chinese product. But I decided to take a chance because both of my chargers at home conveniently quit working on the same day.I used it immediately on my sons car battery, that I had already tried to charge for multiple days trying to bring it back to life, but it just wouldn't charge. So I decided to buy this because it claims that it can repair and rejuvenate a very worn out battery as long as it's not completely dead.And like I said, after many failed attempts with my other 2 chargers I'd give it a try.My other chargers could only get the battery as high as 75%, and that's still not enough power to start his car. So I put this new charger on it and put it on STD (Standard) for a maintenance free lead-acid battery. When I hooked it up, it said my battery was at 75%. So it went through all 7 stages of charging and said my battery was done and at 100%, something I couldn't achieve with my other chargers. So I put the battery back in my son's car and it fired right up like it's supposed to. And because of witnessing this, I would definitely recommend this awesome little charger. It did exactly what it claimed it could do, and for it's very low price, you can't go wrong.

Pros:- I really like the size of this charger.- It seems to work well and lets you know when charging is complete.- after connecting the battery, before plugging in the charger, it shows battery state. I like that it shows the current voltage.- once charging starts, it cycles through information such as voltage, current amperage, temperature. It has a nice battery level “stack” showing progress.- nice strong clips for connecting to the battery.Cons:- the display is difficult to read unless up close. This is a problem in any lighting conditions. It’s just hard to see.- when connecting it to the battery there is always a big spark and loud beep. Talk about startling a guy! This is before being plugged into an electrical outlet (I always connect the battery before plugging in the charger). This unit draws from the battery to show battery state - it must draw a lot considering the size of the spark.- the cables are WAY too short. Although shorter cables are nice when putting the charger away to store it, that’s definitely not the case when in use. Both the cables to the battery and the power cord are quite short. This means you have to have the charger right next to the battery (you can’t put it somewhere easier to see when you’re not right there). You will need an extension cord unless you take the battery out of the vehicle and set it right next to an outlet.- the mode settings selection has, among others, std and wet cell… in my mind a standard lead acid battery is a wet cell. The manual says wet cell is for heavy duty batteries requiring higher current so I’m using std for both my cranking and deep cycle batteries. It seems to work fine.- you can’t change the mode after a while which is good, but touching the display anywhere close to the mode button surprises you with a loud beep. It seems like every time I try to adjust the position of the charger, I accidentally touch that and get startled with the loud beep.Notes (not good or bad):- when charging is “complete” the display shows FUL, but the charging isn’t really completed until it shows OFF.- make sure to select the correct battery type right away as part of your connection sequence.

My car batteries were completely dead, no clicking sound. This charger took some 7-8 hours but it charged it fully. I did not have to remove the battery from the car. This device pays for itself in just one use.Cons : There are some mode button on the device which is kind of confusing. I just plug it and let the auto mode take care. The interface could be better.
