MP00205A

This is proper product. Cheap, effective, and easy to use. It also included a cable to connect to the battery of my motorcycle so I dont have to take the seat off everytime to access it. Its lightweight so you could throw it in your bike storage or backpack on a trip. should be compatible for most auto batterys, even lawnmowers. Acurate description, and tells you wether its charging or maintaining.

These are nice little battery tenders for the price. They cycle thru charging and maintaing the battery as needed. Some I’ve had in the past claim they float but did not and would end up burning up the battery. These ones seem to work properly. Time will tell how long they last but so far so good.

I have a 35 year old Kubota diesel garden tractor that has a full size (Size 65 - 625 cranking amps) battery. This battery has been installed for 8 years+ and just lately it is starting to lose enough charge over a few weeks to not start the tractor. I took the ring connectors from this charger and attached them to the battery and hooked up the charger. The battery was at 12.57 volts upon hookup and within an hour it was at 13.39 and climbing. I unhooked the charger, started the tractor and mowed the lawn. The charger is now permanently installed in my garage and will sit on this battery going forward. I suspect it will gain me another year or two before buying another at $200. If I can stretch this battery just one year, it is making me money. This charger is easy to sure, easy to understand and I found its compatibility with my needs to be spot on. It's functionality is as simple as it gets. Plug it in, hook it up and it does all the rest until you are ready to go. Fantastic value for the money. Save your battery, pocket some cash.

Update 22 June 2024: five down to three was too harsh. It was extremely inexpensive and served well for four years. After searching (endlessly) for an appropriate replacement, I ended up buying another MotoPower unit - their 1.5a version. I figure a device with a little more heft probably won't generate as much heat as this one did, so may last even longer; and it was barely more than what I paid for the first one! Update 19 June 2024: After almost exactly four years in service, The charger died. Wife smelled the acrid scent of burnt out electronics and alerted me to it. It was in use daily for all four years. A while after the narrative below, I had set up a Raspberry Pi to monitor the battery voltage and turn this on when it reached a certain threshold - the backend story is the 2018 Honda Accord has a nasty parasitic draw problem, so it was necessary to alway have it monitored and charged cyclicly. So it was powered on and off from a few times to maybe ten times a day. However, a charger like this is _not_ a complex device; exactly four years of service strikes me as 'planned obsolescence'. So I'm dropping the rating from five stars to three stars. It is not hard to build simple electronics to last decades. There's just no good excuse for a short life - other than to 'encourage' a new purchase. Here's my tale: After a couple of months of driving my car barely once a week during the COVID-19 isolation orders, my 2018 Honda Accord wouldn't start. Tried a jump start from wife's 2002 Honda Civic - still no go. yikes! Got out the decent quality multi-meter I have - less than 8 volts, from a 12V battery. Double yikes! Checked the electrolyte - whoa, one of the six cells had exposed plates. Well, that fairly well explains the very low volts. Topped it up to the line, then tried jump start again...yep, triple yikes. Well, I had plenty of time on my hands being furloughed, so I ordered this little unit. Inexpensive, but it made appropriate promises for what it can do, for what it costs. Ratings good. Some horrible though. Took the chance. At 800mA, this is not going to charge a 500Ah car battery quickly. I hooked it up and monitored the voltage for several days. Weather was rather warm, 80's to 90's F, and I noticed this little device getting pretty darned hot - too hot, in fact. Disconnected it and took off the back plate. Board very hot to touch, capacitor and transformer too hot to touch. Bad design! This thing needs to either be potted with a non-conductive heat sink material for full contact with the inside of the case, or the case needs vents. Period. That much heat will toast those components over time. True - I was asking the device for all it had - to charge a pretty deeply discharged 12V high amp capacity battery. Which isn't _per se_ its intended function. Still though. I decided to DIY. Took a drill and drilled four holes in the back plate, and two holes on each side, see photos. Pretty? Not on your life. Crude but fairly effective? Yes indeed, at least, it allowed _some_ of that heat to dissipate. Eventually there was enough charge to start the car, took it for a long drive, then hooked it up again to see if it would complete the full cycle - which it did after another day. It eventually hit the couple of voltage marks to go into absorption mode, then into float mode. Highly accurate too - 14.19v - still absorption mode. 14.20v - boom, float mode. Repeatable. For twenty bucks, it did what I wanted - and most importantly, what I _expected_ - unlike some of the reviews that complain it took days to charge their battery...well duh! It puts out less than an amp, expecting a fast charge from a slow charge device is just....dumb. That said - please guys - make the 'slotted' sides into real slots, to let some air flow through it. I realize it adds a little to the manufacturing costs, but people will get a longer life out of their (admittedly tiny) investment in this - and maybe fewer will die out in the field, eliciting bad reviews. As for me, I'm very happy with it - because it met my expectations.

I bought two of these battery maintainers to keep the batteries charged in my garaged cars and lawn tractor mower during the winter and they both work very well. Both of them keep the batteries charged and they perform a trickle charge so you do not have to worry about over-charging your battery. My only minor complaint is that I wish they had an on/off switch but I assume the engineers of the product designed it that way to ensure a charge whenever it is plugged into the AC outlet and I assume it would cost more than $14 bucks to do so. This is not a big problem because I plug them into a surge suppressor and that acts as an on/off switch. I just don't like having to unplug a device from the AC outlet in order to turn it off. I give this product 5 stars because it works very well, is durable, and dependable.

Great charger and does its job ! I use it to maintain the battery for my 4 wheeler while in storage. I like that it automatically will switch to maintain the battery when it’s at capacity. It’s extremely easy to use you just attach it to the correct terminals and it’s doing its thing. It was inexpensive and good quality I definitely recommend it.

Nice small charger/keeper for 12 volt batteries. Works like a charm. Indicates when connected properly and when fully charged.

Great product. I'm retired, don't need to drive much but battery goes dead esp in winter months. This little gadget does the trick. Keeps bat charged/maitained. If/when this product dies, I'll buy another.

Macht genau was er soll, einfache Montage, bis jetzt hält er alles Versprechungen und meine Batterie macht keine Problem mehr.

سهل الاستخدام، يعمل بصورة جيدة. استخدمته على سيارة بي ام التي استخدمها لفترات متباعدة. فحافظ على البطارية دون رسائل انخفاض الشحن التي تظهر على شاشة السيارة. المهم يتوصل بالطريقة الصحيحة. حتى لا تتاثر إلكترونيات السيارة.

Compact Works perfectly Easy Clear instruction Recommend for all

Works great for my ruckus

Super merci
