MP00205A 12V 800mA Automatic Battery Charger, Maintainer, Trickle and Desulfator

Works as it should. No problems at all and the price is great

I put this product to an extended test, to determine, if it does what they say. It works better, than I expected. It does have an unusual way it works too. After it completes the first full charging cycle, and goes into Maintain Mode, it will stop charging for 15 minutes, and let battery settle down. The voltage on the battery will slowly fall back down to its own float voltage. 15 minutes later, it will kick back on, with voltage upwards of 14.8 volts, and holds it there, to top off the charge on battery, for 15 minutes. Then repeats this 15 minute cycle setup, as long as it is connected to battery. If a load is applied to battery, the charge cycle is repeated, until voltage on battery gets full charged, then the 15 minute cycle kicks back in. I thought at first, that the battery itself, was causing the cycle, I was seeing, but I tried it on two different batteries, one was a 5 AH, the other a 15AH, and I got the same results. Main thing is, this charger does keep your battery topped off, and ready to use. This is a very good product. And as a note, I wasn’t paid for this review, I am very happy to tell others, when I find a products that exceeds the data, in its description.

Used these devices on 2 car’s batteries when we were out of town for 2 months. Inexpensive, easy to use and worked as advertised. Cars started right up when we returned.

I used for the car and the bike and it did the job. It requires time (min 8h)

For the price this has turned out to be a pretty good battery maintainer. I installed it on my mini excavator since it gets limited use. The battery has been topped up correctly to an optimal float voltage, and after testing the battery with a Midtronics tester, it shows better State of Health (SOH) on the tester after I let this maintain the battery over the course of a week. is this super high quality? No. The charger seems decent, but the clamps are ultra cheap. I used the ring terminal connector which was better quality. I wouldn't want to attach and detach this from various batteries as I'd see the cheapish clamps failing pretty quickly. I could be wrong, but my gut tells me I'm probably not.

Nice product, well built. Has clip and eyelet connections. Works silently and steady.

Use this for portable generator, works great.

Put under Waverunner seat and ran all summer with no battery issues

J'adore ca et très pratique pour mon Quad. Pour garder ma batterie full surtout l'hiver

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

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

Easy to use and works as expectes
