### ⭐⭐⭐⭐⭐ YUASA YUA1AMPCH ... A Worthwhile Purchase
*by D***R on December 25, 2019*

Update: 04-06-2021A 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".

### ⭐⭐⭐⭐⭐ Good charger
*by S***T on February 19, 2025*

I have had this product for a couple of years now. It has been used year round keeping the battery charged on either the motorcycle or 4 wheeler. Definitely worth the price.

### ⭐⭐⭐⭐⭐ These Yuasa tenders should be in top 20 at least.
*by P***Y on October 5, 2023*

I have 2 of these battery tenders. The first one is 900mh and is more than 10 years old. The second one is 1 amp and is 5 years old. They have been used to keep motorcycle batteries topped off. They have been plugged in continuously except when riding. The 900mh version was on the same battery for 8 years winter and summer. A mechanic friend convinced me I needed to replace the battery just based on age alone. Like an idiot, I got the battery tested AFTER I had already replaced it. It tested good so there was nothing at all wrong with it, no reason to replace it. It was still completely functional from being kept on the Yuasa tender.Because of this I bought the second one for another motorcycle. I haven't had to replace either motorcycle battery are 5 years.I do not understand how these battery tender, now tender/maintainer are not in the top 20. The price, now $50, probably keeps them from being #1 but based on their longevity they should be. 4.7 stars already. Yuasa is a well known name in the motorcycle industry for 7 decades. Yamaha motorcycle I bought in the late 60s came with a Yuasa battery. Nuff said
