Hard to read settings on front of the charger:  not sure if the charger is doing what I would like it to do.  No "ON" "OFF" switch makes it inconvenient to find the plug to "UNPLUG" it to Turn it Off.  Seems to charge good batteries OK, but does not seem to want to charge batteries that are down on voltage that my old charger would add a charge to.  May be a good detector on batteries that are beyond "good life", but does not charge them at all, where my old charger would.  MIGHT BE THE CHARGER YOU WANT FOR AN EXCELLENT CHARGE MAINTAINER of batteries that have draw down on them over time.

Great product so far, has recognized every course automatically. Just remember to recharge after your round. You don't need to order all of the extra chargers unless you have a need for thr car charger.

Not all Battery Pack brands can Charge and Be-Charged at the same time !!  I also bought some Kmashi units which are good, but when you start charging them, they turn OFF the power output to your phone.

For my use, I need a unit that can do both at the same time.

Some late model German cars have no live cigarette lighter outlets when the ignition is off.  For car-club race track events I need power all day for some GPS-VIDEO-SPEED recording equipment.  This unit does the job perfectly, even though the car ignition is off more than its on during the day.

IT CHARGES YOUR PHONE FAST !
It take about 4 hours to fully charge my phone plugged into the wall and longer with car chargers.  This unit charges my phone in 1 hour.  So I also use one in my Kitchen just for the charging speed.

I don't know how long this low priced unit will last, but it is great when its working.

This Stanley BC6809 6/8 Amp Automatic Battery Charger performs brilliantly. Just connect the charger's clamps to the battery then plug the unit into an extension cord. After that, the microprocessor performs necessary adjustments to charge the battery. When it's finished, the lighted LCD display will display "Float" which means the battery is fully charged and being maintained at that level.

I highly recommend purchasing the Stanley BC6809 automatic battery charger from Amazon.

i keep this trickle charger attached to my automobile battery when the vehicle is parked at home.  i leave it outdoors and forget about it, except to check the voltage in the battery once in a while.  it maintains the battery at 13.32 volts constantly and is ready to go when i am.  i do not drive very often, maybe once a month, so this device is ideal to maintain the charge in the battery.

Works great! I reconditioned the batteries on the cars and have it maintaining the battery on the weekend car (2006 Boxster). Battery is always ready to go! And it's so much smaller than the battery chargers I've had in the past. Couldn't be happier.

This unit works good and fast and is rechargeable. The manual model works just as well for the small quart bags if you don,t mind a few more seconds of use.

I purchased this to maintain the battery on the C7 Corvette. Based on the Corvette forum, this is an excellent choice to keep a Corvette battery charged when the car is not driven often.

The unit is about 1/3 of the price of the Chevrolet Corvette CTEK version sold by the dealer and comes with the necessary 12 volt power socket that fits in to the vehicle's charging inlet located next to the battery in the rear hatch of the Corvette.

The unit is simple to use. You insert the power adapter fitting (cigarette lighter adapter) into the car and plug the unit in. The microprocessor monitors the battery and charging status and the status light shifts from full on to cycling once the battery is brought up to the proper charge level. From that point forward the charger will monitor and cycle up as needed to keep the battery charged.

So far so good. I have charged two batteries with it. I read reviews that it charges too fast and that it can hurt your batteries. I have not experienced that. Its great, its automatic, it is fast and I like the digital readout to tell me what percentage the battery is at. It can also tell you if your alternator is not putting out enough charge and therefore, your alternator is the culprit and not your battery.

Smartest tender/ charger I've ever used and cheap too! Active monitoring charges intermittently as the battery can accept current and actually shuts off when the battery is "full" so you don't boil off electrolyte or warp plates. MOST important is that it will take a good battery to 13.2 volts where they should be. Every other charger I have, fancy or plain, only gets to about 12.6V

A word of caution, make sure you're buying THIS charger. Schumacher makes an identical looking unit (in the same case, different stickers) that isn't smart and doesn't reach the 13.2 volt charge necessary for optimal battery life.

This unit worked as expected. I had installed the volt/ammeter in place of the analog ammeter in a Schumacher model SE-1010-2 battery charger. After gutting out the old ammeter and a little judicious use of a flat file, I was able to insert the display case into the ammeter housing. Since this charger only puts out 10-15 amps max, I removed the 8mm connector bolts from the ammeter shunt bar and used the 2 smaller screws to make the electrical connections after gluing the shunt to a block of wood and glued the assembly to the charger case front.

The connection diagrams that come with the unit are quite usable and clear (Of course I've been an electronics technician for over 45 years). There are adjustments on the display to set the voltage and current being displayed, but I found the readings to be fairly close to the measurements I made with my test equipment... Your mileage may vary.

I bought this battery charger locally because I needed a charger and I had loaned my old, manual charger to someone who never returned it. My daughter had left the dome light on in her car and when she tried to start it all she heard was the starter solenoid clicking away. It worked quite well for that purpose, started the car right up.
I should mention that I have been working on cars since I was in high school and did it professionally for a while. So I like to think I know my stuff. Also I embrace technology and can see the advantage of a smart charger...right?
A few days ago I was at home and needed to go to an appointment. Everyone in the house was gone, and the only car left was my 2006 Saturn Ion, which I had not driven for a couple of weeks. I got in and turned the key. Nothing dead as disco.
No problem right? Just hook up my handy dandy smart charger. That is when I found out that this charger, and all automatic chargers, will apparently not charge a dead battery. The charger acted as if the cables were not connected. Googling the problem was very enlightening, apparently the computer chip in the unit does not "see" the battery if the voltage is too low. So if the battery is really flat, it will not work. Typically you can revive a battery like that by charging it slowly. But not with this charger!
Luckily I had a 115V gasoline generator with a 12V auxiliary circuit. I charged the battery for about 30 minutes using the generator then all of a sudden my Smart Charger decided there was a battery there after all and started the car.
So my takeaway message is this...the charger has limited usefulness. If you have a battery that is really dead, it will not work. I understand why they build them this way, it is to prevent people from hooking up the charger and walking away and cooking the battery. That's fine, but there should be a manual override to allow you to bypass the chip and just supply juice.
I ended up buying a nice, simple Schumacher manual charger from Amazon and giving this one away. For topping up a battery in long term storage or one that is a little weak, it's fine I guess. But this is not the type of charger you will ever see in a service facility.

A very good slow charger for Deep cycling SLA battery. I almost killed my battery earlier using a normal car battery charger of 10A charging current, 1 minute later I heard boiling sounds from the battery, before I realised SLA battery can only be charged with c/3 max current. CHARGE MASTER 750 perfectly completed the job, it is very safe to use as it is only 0.75A charger. I am using it in Asia with 240Vac supply, it is perfectly doing the job.

The charger arrived on-time and in excellent condition. I have not yet used the 12v adapter, but the flip-out 120vac works great. I like the way the charging LED changes color to tell you the status of the charge.

This was the second unit after the first died.  I had another one that died after about 6 months.  They seemed to work well at keeping constant charge but once the battery goes flat or a cell shorts out the current regulating circuit must be failing and not limiting thus burning up the output stage of the charger.  I get these for customers in Florida that must keep their cars on chargers for months at a time that will not pay extra for the $50 units.  At least they are something.

I have had many other Schumacher chargers and can ONLY recommend units with simple analog output meters - they just work great.  Trying to figure out the battery status from these error lights is useless.  Spend the extra $20 and get a GOOD unit with meters and you will NEVER regret it.

I use this mainly for my motorcycle during the winter months.  I find that it is not only very easy to use, but the charger monitors when your battery is low, and keeps to the proper level.  I bought this about eight years ago in a department store, and it worked fine for many years.  But when selling a previous motorcycle I gave the charger to the party who purchased the bike.  About two years later I purchased another motorcycle, and I could never find this charger until one day I when out to Amazon, and immediately bought it.  I highly recommend this unit to anyone who needs a good automatic battery charger.
