Battery Charger 6-Amp 12V Automatic Smart Battery Trickle Charger, Battery Maintainer Desulfator with Temperature Compensation for Car Truck Motorcycle Lawn Mower Marine

It fully meets my needs. When charging the battery, it will automatically adjust the charging speed to avoid overcharging and effectively protect the battery life.

Very easy to use right out of the box—just one button to cycle through all the modes. I’ve mostly been using the repair function so far. Hooked it up to a dead extra battery I had, and after letting it run for a full day, it actually brought it back to life (we’ll see how long it lasts, but still!).I also plan to keep it hooked up to an extra car I don’t drive much, which should save me from having to start it up regularly just to keep the battery from dying. So far, it’s doing exactly what I need it to.

Small but does the job. Will even work on tractors. Doesn't take long to charge. I was worried about how small but it works great.

This is a great product! It uses advanced trickle charging technology, which is not only efficient but also very safe. I am very satisfied with this product and it is worth recommending to everyone!

This worked out great for keeping it handy for my older battery. This brought back some life to my battery. The operation and functionality is pretty simple and easy to use. It has been made with quality materials, hoping it will last long. It does come with long enough cable that helps plugging it to my battery from garage outlet. Well worth the money.

This product works great, chargers anytime of battery from a completely dead and brings it back as long as battery is still able to charge. Length of cord and and alligator clips are great size.

Ariived on time. Used twice and currantly using. Appears to be working. Only time will tell. I hope to update this report positively.

At $20 this 12V 6A smart battery charger is a good deal. It seems to charged up to 6A (for a few seconds then drop to the 2.5A range.) The charger will automatically identify the battery voltage and uses that to charge. The 2-prongs power cord is a little thin but it does the job. The temperature shown is only in C. It does not cycle indefinitely when trickle charging (shut off after one cycle.)
