TOPAC 2.5/5A 6/12 Volt Automatic Car Battery Charger for Automotive, Motorcycle, Boat & Marine, RV, Toys, Power Tool, Lawn & Garden Battery Systems

This is a very capable charger. A real life saver for batteries in a cold climate. It has many automated functions for reviving and charging a dead battery. After the battery has been returned to full charge this charger will automatically maintain a trickle charge to maintain the battery at its top charge voltage. Although all of these steps are automatically provided by this charger you have to select the mode via push button each time it is powered up. Many other less complex, and capable, chargers are simply turned on. This much more capable charger requires one additional step. It is well worth this one additional step.I also found the connectors and cables to be much more practical that less capable and possibly cheaper chargers. All connectors are keyed to prevent accidental reversal of voltages. All of the cables were longer and of higher gauge than other products I’ve used. I was particularly impressed with the cable that is provided for permanent installation to the battery. The round conductors were large and provided great contact. I have seen many other cables like this that may have been used on a lawn mower battery but were too small to be installed on an automotive battery.

Pleasantly surprised by the quality of the product. For the price I didn't expect it to be so nice. Came when it was scheduled to, with a tracking number. I don't know if it's waterproof, haven't had a reason to test that capability. IT IS WELL WORTH THE MONEY! It has a rugged exterior with nonslip rubber, quality connectors, and even a bag to keep it all in. I bought it for my scooter battery and researched multiple units, and even hesitated on ordering this one because of the mixed reviews online, but I am so glad I took the chance! It's a great deal.

The day these arrived, my car battery was low. Very easy setup. My battery is old and was around 70%. This charger worked efficiently to fully charge it. Since the battery was old, it took about a couple hours. Just left it hooked up, did my thing and when I checked it a couple hours later, it was 100%. Excellent quality charger with no complicated buttons to setup...just a mode button that switches from percentage to voltage readouts. Glad I bought these.

I have an electrical leak in my GMC Yukon that slowly drains my battery, especially on cold nights. I was able to put this directly under my hood, so I leave it there all the time and plug it into an extension cord at night. It keeps my battery charged so I can start my car early in the morning without having to jump it every time.

Works great! My RV battery stopped holding a charge And everyone told me to throw it away. I got this thing and it works just like it was brand new now! Save me $200 Or more on a new battery! This was a lifesaver, considering I need a battery for my furnace and it’s really cold right now!

It’s great for the price & it works just as good as any well known brand. I highly recommend getting one! I’ll be ordering another for my storage generator!

Ok for the money I guess, but it only lasted less than two years even though I didn’t use it very much. My old Sears battery charger lasted more than 30 years.

Worked ok until it simply quit. Er1 flash and no way to make it stop. Cost me a new battery and I also have to get another charger.
