AmpeakBattery Charger,2A/8A/15A Car Battery Charger,6V/12V Fully Automatic Smart Battery Maintainer with Winter Mode, Auto Desulfator, Battery Recondition, for All Lead-Acid and LiFePO4 Batteries

I've reviewed and tested a number of battery chargers for use with standard car batteries and gel/Lithium batteries. This one beats them all in the sub $100 price range.The display actually shows useful data like current charge voltage and amps, as well as correctly detected the battery type.And, the clamps are excellent given they have soldered connects with a jumper to the other side of the clamp. Not just a single crimp connection (which with time can develop a high-resistance point and get hot,) but soldered electrical contacts. I've experienced the crimp-type electrical connection getting so hot it burned my fingers (on that unit, I then remade the crimp connection and soldered them.)Well worth the price!

Easy to use. Will charge a completely dead battery. This is the second one I have had. First one I was charging my boat battery when it rained. They are not made to leave in rain.

I bought this charger in July and returned it in August.Pros:1. Easy to use. Hook up the cables, plug it in and it does it's thing.2. Light weight3. Led screen easy to readNow for the concerns1. On one battery, the battery started over heating while going through the repair/charging cycle.2. On the last battery, the positive cable clamp began to melt while charging. Reason for the return. Maybe plastic is not the way to go with these clamps.3. Ampeak customer service never responded to 2 separate inquiries.4. Amazon customer service was helpful, but a bit flaky. I spoke with three customer reps, who provided different stories how they would rectify my issue. Two reps told me I wouldn't need to return the damaged unit and they would have another unit sent out. That did not happen. Finally on the 3rd attempt, the rep, who I believe was a supervisor, said I would have to return the unit and they would refund my credit card. From there she told me I would have to reorder the unit.Overall, I did like the charger. I haven't decided if I'm going to buy it again yet and eventually change the clamps to metal ones.

My old Schumacher charger lost a diode and started to ruin batteries instead of charging them, so I hunted around and found this.In the almost 20 years since I bought the Schumacher, battery charging has been taken over by microprocessor-controlled chargers that do multi-stage charging, desulfation, etc. It's nice to have a charger that will automatically transition to a float charge once the bulk charging is done. It's handled every battery I've thrown at it, from automotive to lawn tractor to sealed lead-acid out of a backup power supply. That's the good part.The bad part is that you won't rescue a really dead battery with this. The battery in the backup power supply was stone dead (like less than 8v-- really REALLY discharged). This charger refused to charge it, claiming it was defective. Since I had nothing to lose, I hooked it up to a battery tender, which is just a low current trickle charger meant to keep a stored battery from discharging. After about an hour the battery tender had brought the voltage up enough to where the charger would recognize it, and it charged the battery without further complaint. That battery probably won't live too long after all the abuse it's received, but since it's only used for short periods of time when the power goes out, it shouldn't have to.In short, this charger works fine under most circumstances, but be aware that it does have limitations when trying to resurrect heavily discharged or neglected batteries. Since I end up doing this far more often than I really should, I ended up putting a new diode in my old Schumacher charger. I hardly ever use it any more (this new charger really does do a nice job), but there are times when you just need a "dumb" charger to get the job done.

Not bulky and heavy like most, pretty small really with a lot of features! Ridiculously simple to use, it defaults to automatic standard charge mode and you really don't have to push any buttons if you don't want to. Huge clear display is intuitive and tells you precisely what is going on. It scrolls through charger voltage/percentage charge and what mode it's in (ie float vs recondition etc). Other brands either have vague leds or you have to push buttons to get voltage/percentage if even available.I have not used it to start a dead battery but I have no concerns about quality.The recondition mode is NOT a gimmick! I took a totally dead battery that had been in a dead car for over a year to full charge and holding. Last time I touched this battery I couldn't even jump it after trying for 20 minutes...it was totally worthless and wouldn't even turn dash lights on. Incredibly impressed. It could not save an old deep cell I have, however, this charger said bad battery when all other 'smart' chargers I've tried it on just charge it and never detect the internal short and lack of storage capacity!It is quiet until the fan kicks on over 10A charge then the thing really moves some air! Was impressed with the cooling compared to other chargers.Long story short I made an uninteruptible power supply with an inverter. This charger actively scans the battery and automatically switches from float to charge. "Big deal" you say...they all do that. But they don't, almost all chargers are either slow/low amp maintainers so they don't melt the battery, or they charge to 100% and float but won't switch to higher amps if there's a drain or short on the system (ie leave a light on in parked car). This charger is the only one I've come across that actually switches back and forth between modes...and it's a third of the price of some others I've tried and returned!

Works good. Husband uses it all the time.

Compré un producto para que me diera servicio mucho tiempo y la verdad me decepcionó y lo peor de todo es que no la cara dan para la garantía!
