I purchased this to maintain my motorcycle battery, however it works well for my small car (430 cca) battery too. On both batteries it slowly tapers off the charge (both charged and charging lights on as described in the instructions) as the battery nears full charge; 14.5v for lead acid batteries. If you want to know the health of your battery, check the voltage 24 hours after charging. It should be at least 12.5v at around 60 degrees. If it is less, you battery is starting to show some effects of age. I haven't had to bring a car battery back from the dead (<12v for lead acid), however this is not the correct charger for that task due to its low amp rating. That's why it is called a maintainer. Overall, I'm very happy with it.
I have bought about 4 of these in the past 2 years and each one has never lasted more than a few months. The first two I dropped from a height of about 3 feet. They are my fault (even though they should be able to take some abuse) but the other two the condition lights stop working and it freezes on the green fully charged light or no lights at all. I hooked one up the other week to my Harley. It showed a green light. Left it plugged in. Went to start the bike after two weeks. The green light was still on. Guess what?....Dead flippin battery. I also have a battery cutout switch so it wasn't anything on the bike. These things are junk.......I buy alot of Chraftsman stuff but these are terrible.........thanks
I have 6 of these chargers and have used this style DieHard maintainer for over 5 years. They are easy to use, reliable and I've had no issues at all with any of the units.
Great product, computer said they have it in stock, sales person could not find product, now i'm waiting for it from the store & they said it would be a few days until they would have it.
I utilized this item to charge the pattern on my lawn tractor. It did exactly what it was designed to do; it charged the battery. The nice part was, that it also came with different types of connectors for multiple applications. For twenty-five bucks, you can't beat it!
