I got this to replace a Harbor Freight cheap charger I used 1 year before it stopped. On sale this was about 2 times that so if it passes the 2 year mark I am ahead. I placed it on 3 batteries, car back up, a motor cycle, and a scooter. Each charged up readily. The car took longer and did not get to 13 volts, but close. The 2 smaller batteries did get to 13 volts. Not an expert on batteries but I learned if you keep them on a slow charge they last longer. I have it off the batteries now to see how long the charge lasts. The car battery is for jump starts. I found keeping an old battery, and having it charged negates the need to buy an expensive car jump box thing. My old battery was from the last time I got a new one, and was in fair shape. Not turning it in cost me the $10 exchange fee, so for $10 I have a back up jump starter I can use with the jumper cables I already have. I will update if any thing changes. For the price I am satisfied. It just has small lights but the expensive ones with all the meters does not help.

It works great and recharged my fully discharged car battery in about 22 hours. Customer service is excellent as well. Be aware, however, that the instructions that I received with my unit said that the unit is not properly charging if the middle led light is not "twinkling", whereas the unit itself says there is an error in charging if it IS "twinkling". The answer is, if you see a steady red in the middle led, it is charging properly and the red will turn to green when fully charged.

After researching trickle chargers and reading the reviews of all of them I could find, I chose this one based on those reviews. After reading reading a review of how another trickle charger made by another company actually caught on fire, I was hesitant to buy one at all because it will be used to keep my breakaway trailer battery charged during long-term storage. In the winter, my expensive cruiser. The Foval charger had the best reviews and the lowest negative reviews so I ordered it. Shipping was fast, the product seems well made and the price is right. I plugged it in and it's working. It's as simple as that. Of course, only time will tell if there's an issue but I will update this review if there is.

The three stage charging system was the best selling point for me.
I liked the wiring harness that is easily setup on any smaller battery as well as any battery that has any kind of terminal screw.
The LED readout seems to work well, however it can only be seen if you are close to the charger. Maybe making the LED's sit closer to the outside face of the charger would help. Overall, I am very pleased at the performance as it replaced a float voltage charger that only had one stage.

One of the things I like about Amazon is the feedback system. It can be especially helpful when you have limited experience with an item or brand. While not an expensive item, I did want to get a trickle charger that I would be happy with so I not only reviewed all the features and prices but also the feedbacks - and I came up with the Foval. Great price and full featured with the simplest operation and confirmed by really really good feedback.
Now that I have mine in and have used it (and bought a second for my other garden tractor) I think I made a really good choice and can agree with a 4.8+ star positive rating. Just connect the leads and plug it in. No settings, no buttons, switches, etc. The lights tell you the status and you are in business. AND the cords are long enough that I did not have to deal with extension cords.
