This is a great charger/maintainer, which I have used before. This is my second one. Both are for YUSA motorcycle batteries. I figured it would be best to keep the brands the same.

Despite it being small, this is actually the BEST of the 5 or 6 chargers/tenders that I own. Not kidding. Especially as a tender, this keeps the battery topped-off, but never over-charged. It dumps any overage. I check my batteries often and they never heat up on this tender.
I have a real workload, and this tender has no problem keeping up with any of it:
I have 3 Harley-Davidsons so that means I ride them each only about twice a month. Even though I’m in Florida and I can do this year-round, I still need battery tenders because the alarm systems drain the batteries on the bikes, and also any kind of lead-acid battery is simply going to drain over time (that’s science folks).
I can’t find any problem with this tender, and it simply works, and works properly. I have no idea who actually makes it (Yuasa, probably Chinese manufacturer near Guangzhou) but it’s very good quality.

UPDATE: I have now owned this charger for 18 months and it is working well. I do notice that it used to get to a higher charging voltage before (14.4V, now closer to 14V) and maybe a bit lower maintenance voltage. Perhaps it is a battery issue. I have no problems with the clamps or cables.
I was looking for a battery maintainer and purchased this charger based on the excellent product reviews. I bought a used car with a tiny
32AH weak battery that is not old. The car starts well but the battery voltage drops to 12.0-12.2 volts after 2-3 days of sitting and the acid is also weak, even after charging with my old-school automatic charger that eventually trickles. I bought this charger because it has a higher charging voltage. My old charger goes to 13.8V or so. I connected the charger when the battery voltage was 12V. It slowly went up to about 14.4V and then the green light came on (maint mode) the battery was kept at 13.5-13.9 volts. Perhaps I could have just used my old charger as it won’t overcharge but I will save that one for 10 amp charging of heavily discharged batteries and the Yuasa for topping off and maintaining, as it was designed to do. It gets a bit warm in a 80 degree garage and I have no issues with the design or functionality. If it lasts, I will be very pleased.

El producto super practico para mantener la vida util de la bateria, ademas de hacer carga, tambiien te indica el estado de la bateria con el indicador de LED, es facil de conetar y su cable anexo permite que cargues la bateria aun montada en la motocicleta, totalmente recomendado para quienes usan la moto con poca frecuencia.

Works as advertised.

works as advertised and the battery wire clamp is a boon. I am from India, and I bought a seperate 110-220V step up transformer for this charger, and I have used it couple of times now works like a charm.

Update: 04-06-2021
A brief update to this charger. Vote status elevated to five stars. I love this product. It has stayed connected to my Camry battery whenever I’m not on a long haul to Virginia. My battery behaves as if brand new and I believe, without a doubt, the service life on it will be a very long one.
Liking this charger so much, I returned for another purchase (2021) … a Yuasa YUA1203000 3 Amp Automatic Battery Charger and Maintainer. This unit, although used frequently, is used as a travel companion and a charger for an ailing family member when out of state. This unit de-sulfates, a very useful function.
All-in-all, I love my Yuasa chargers. Buy one .. I think you will too.
=======================================================
*** Note: I believe the YUA1AMPCH in my review is the Yuasa YUA1201000 I ordered … just an updated code or model.
I purchased this unit for my 2007 (52,000 mi) Camry which stays stored most of the time except when traveling out of state. On average, I’ve been connecting/disconnecting my larger battery charger every three weeks to keep the battery in shape. Frankly, due diligence can get tiring.
The maintainer/charger is easy to use and came with two sets of terminals configured with an insulated quick-connector for safety. The first set uses battery clamps and the second, eyed terminals for permanent connection to the battery.
After some brief testing, I connected the eyed terminals to my 5-year old standard “wet” (not AGM) 12-volt battery. Since the YUASA is more useful (I think) as a maintainer, I used my Schumacher charger to top off my battery and then deployed the YUASA.
Over the course of six weeks, I periodically monitored the charger’s activity by testing the battery’s resting voltage with the YUASA still attached. When actively charging, the battery’s voltage would register as high as 14.11 volts on the meter. When resting (several random checks), I found the voltage to hover between 13.61 and 13.67 volts. This is acceptable, per a little research on BatteryUniversity.com .. which by the way, deserves a permanent bookmark to your Favorites folder.
I did however, notice a bit of nuanced behavior (will describe in a minute) .. that lead to my 4-star rating instead of five.
When checking the battery voltage level, the YUASA would start charging the battery if I left the voltage meter connected to the battery for more than a few seconds. I consider this to be rather strange since voltmeters draw practically no voltage. I would rather have seen the reading stay level instead of going back up to 14+ volts which it invariably did each time I tested. However, as a more positive thought, this quick tendency to start charging again speaks to the unit’s sensitivity.
In an effort to more fully understand the charging behavior I called YUASA’s technical support number and spoke with an individual that characterized herself as qualified to address my technical questions. It quickly became evident she was unable to conceptualize or process my questions (see above detail) and began reading from her scripted text to conclude the YUASA was “only manufactured for high-performance style batteries and -NOT- for car regular batteries”.
Surprised by her statement, I called her attention to page four (4) of the owner’s guide stating, “Suits all lead-acid batteries. (Conventional, AGM & High-Performance AGM”). She was mystified by my disclosure and found herself completely unable to respond. I asked her if the statement in the Guide was wrong. She couldn’t answer except to repeat her earlier statement that the YUASA was only for “High-Performance” batteries and not regular car batteries. As it had become clear she wasn’t close to the answer-person I was seeking, I asked to speak with one of their engineers. Instead, I was referred to a salesman who was perhaps more capable but equally unable to address my questions other than to affirm it worked on all 12-volt “wet” and AGM batteries.
From this, it may be concluded YUASA’s technical support in PA lacks any real technical support training whatsoever. Buyers should consider this if true technical expertise might ever be needed. And perhaps to be fair, I might have been over-reaching with my expectations for an answer to my questions. However, it was important to more fully understand the YUASA’s charging behavior as over-charging will considerably shorten a battery’s serviceable life, thus negating the purpose for a maintainer to extend it.
So in short, I like the YUASA very much but only time will tell regarding its reliability. What I can say is the device has -NEVER- left my battery feeling even warm (good sign) and after nearly six weeks of resting, the Camry fired up yesterday like it had a brand new battery installed.
Readers can expect that after several months, I will report back to let everyone know where things stand with the YUASA. Otherwise, at this point, the YUASA is a solid “buy”.
