Schumacher Electric 6A Car Battery Charger and 100A Engine Start, Maintainer, 30A Boost, Battery and Alternator Tester, 6V/12V Batteries, SC1564

Very powerful Multi Charger Setting it up is sometimes is not clear and id say it would benefit from a proper LED display to make it clearer, sometimes I'm not sure if its doing anything, on stand by, or just thinking about its next move.... But once you get it figured out its a huge step up in charging those higher capacity LiFePO4 battery's . Its obviously been built for a working environment so its heavy duty in construction and all the cables are adequate from the box

I've been using this charger for a few months now, but only in the 2–6A and 30A modes, and it has performed exactly as I hoped. I use it when working on my BMW, including long coding sessions where the car has to stay powered on for over two hours. Each time, the charger kept the battery fully charged and stable with no issues at all. I haven't used the 100A engine start feature, so I can't speak on that, but for regular charging and maintaining, this unit has been reliable. After every session, my battery showed a full charge immediately, which tells me it's doing its job well. Overall, I'd recommend this charger for anyone who needs something dependable for occasional use. I've used it around 7 or 8 times in five months, and it has worked perfectly each time. It may hold up to heavy use as well, but I have only used it occasionally so I can't say one way or the other. It's simple to use and so far—no complaints.

no dislike only loving it is the best charger i ever had i had one let someone use it they were in a car wreck throwed it in floor a broke it i ordered a new the next day once you have had one of these the others just dont do what this one does it will take dead battery from 6 volts to 13. 4 in ab out 7 minutes works great tells you voltage when you turn off charge and great price chris

I've only had one opportunity to use this newly purchased, automotive battery charger and I am impressed. I had a newer battery that sat for months without use and its charge was so low that my old charger would not charge it. When I hooked up the new charger, it did not hesitate and fully charged it in a matter of hours. I highly recommend this Schumacher battery charger.

Selecting the mode and battery type is a bit confusing. I also wish I could make this show a percentage of charge, or a voltage instead of it just cycling between the two. My only complaint is that it automatically chooses AGM battery type when its powered on, instead of standard. I think standard should be the default choice. It will start charging your battery even if you have the wrong battery type selected. Overall, it works. I can't think of better praise for a tool then to say, "It does exactly what it is supposed to do, and it does it well." It charges my six and twelve volt batteries without any issues, and it does it pretty quickly. The booster and starter function both seem to work well, also. Great tool, especially for the price.

this charger has saved my batteries many times. It will sense lower voltage batteries to start a charge unlike other cutters that need to see higher voltage to enable charging. it can de-sulfate the plates. the cranking amps are great for the jumps. bought another after my first was so good.

For one good thing, if necessary, this charger will recover a dead battery, unlike a majority of chargers being marketed in the a little under/a little over the $100 range. I did look into chargers pretty deep in this range. There was another stand out but it was in another brand, and I've been familiar with Schumacher for years, so that is what I bought again. As for the charger itself, it's heavier than expected, so if weight of the works inside equals quality, it has it. The cables aren't as heavy as I'd like but neither are any other chargers is this price range. The clamps are a thick plastic but I do think they will last, clamps are small so they'll fit tight in tight places, and the springs in the clamps are strong, so they'll wear better overall too. There's not a lot of instructions included, just basic to do's %26 don'ts, if the battery is in the car or out of the car, and a lot about safety that you should read if you're unfamiliar with charging batteries and chargers. To use it's basically automatic after you select the battery type. It determines the state of the battery and starts charging or lights indicator lights for "Bad" or "Desulfation" mode if the battery might can be recovered. You could hook it up, plug in, select a rate if you want and press start, or walk away, and it will run through an automatic cycle something like this, depending on the condition of the battery, it gives the battery a 30 amp boost then automatically adjusts the charge rate according to what is needed with multistage charging. Then it switches to 6 amps for the final charge cycle, then switches to 2 amp for maintaining the battery until it is put in use again and lights the "Charged" green light. It includes a battery %26 alternator tester and a 100 amp engine start feature. Compatible with Lithium LiFePO4, marine, and 6 volt batteries. Like I said I did a lot of comparison shopping and this charger I would buy again. I'd give it 5 stars but nothing is perfect.

The product works but it needs a wall outlet to charge the car battery so I had to use an extension cord

charger works as it should, but I purchased it and had it delivered, when it arrived it was clearly a used open box return. box not sealed, no inner packaging, no instruction manual. if I had purchased it at the store, I would have pushed it aside and taken the sealed unopened one. that being said, it does work as expected and having it delivered was convenient I just feel like it should have been sold as an open box return with a discount

Not really a review on the item itself it seems of good quality although I have not used it yet it was described as new in the box the box had clearly been opened at one point and the owner's manual was missing pages so clearly not a new in the box product probably someone bought it charged their battery with it and returned it I would assume and that's what I got
