Product Features:
The MOTOPOWER MP00205A 12V 800mA Battery Charger allows you to connect the charger to the battery and leave it for maintenance indefinitely.
Once the battery has reached a 100% charge, the chargers will automatically switch it’s output voltage to a safe, storage/float level (13.6V+/-0.2V) that eliminates the need to worry about the damaging effects of overcharging.
Pulse Current Recovery Mode:
In the Absorption Mode, the charger will give a 0.5Amp pulse current to charge and recover the battery until it’s fully charged. In this stage, the charger will decrease the battery sulfation and improve the battery performance gradually. For several times charging, you will find the battery internal resistance is lower and the performance is improved.

Great Charger
I’ve been using this charger to charge 3 go kart batteries so far. It works great as far as charging them to 13V and slow trickle charge them over 13V. I like the fact that trickle charging is safe and no need to disconnect immediately after fully charged. So far so good. The device is small and easy to use. I believe it’s worth the cost of having a safe charger that you can depend on.
Robert Kakuk –
Simple, cheap, and works GREAT
This works great! Skeptical because it is cheaper than most, but I put one on my compact tractor and fork lift (small battery and car battery) after checking voltage and percent charged. Checked two days later and both were 100% and max voltage, while the charger was in maintain mode.I will buy this again and recommend.

Works as it should so far.
Set up on a older battery and the charge was restored to 12.6v

Keep expectations reasonable, maybe do a little DIY modding, and it’s a great purchase
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.

Nice trickle charger
Works well and easy to use
Scott of Woodbury –
Seems solid!
Have only been using this over the last few days but it seems to be working great. I like that you can see the different stages as the charger runs.SS
Jon –
Great deal
Works well and was an excellent price. I bought two. Time will tell on longevity. If it doesnât last Iâll update the post.
KT –
got HD started after 3 months dead battery!!
charged overnight and Harley Davidson Street 750 with dead battery started. didnt even have to take the batterry out, and it starts fine now. easy too and it was the cheapest one!!

Son totalmente originales, funcionan muy bien para hacer una carga lenta a alguna bateria, lo cual puede ayudar a mantener la salud de la bateria, y como mantenedor de baterias funciona muy bien, siendo compacto no ocupa espacio y permite tener bien si se almacenan las baterias.Muy recomendable calidad precio
