Rated 4.8 out of 5 by 41 reviewers.
Rated 5.0 out of 5.0 by DOES THE TRICK, OR SHOULD I SAY TRICKLE...... Have a car that is sitting in garage now and the battery is slowing being tapped , so I hooked this up and in about 24 hrs. , brought it right back to snuff...I followed the next week and it only took about 4 hrs. to top it,,,,,,.I do agree with others the volt. selector switch is too easily moved from 6-12 volts....but just be careful or tape over it....It's better to slow charge a battery than rapid with higher amps in the long run.....and this is about 1.2 amps..vs.. 4-10 amp units....

Rated 5.0 out of 5.0 by Terrific unit I found myself in a situation where I had to store my motorcycles remotely, while I moved cities. At home I used a an ultimate unite that I swapped between 3 bikes, but with a move I had to store the bikes a 2 hr drive away for several months and I had to find an alternative, reasonable cost solution. The ultimate is a great device also but way more costly. I decided to order two of these B&D units as I have always been happy with their products. I researched the background and figured if B&D bought the company that designed these they must be OK. I hooked up two of my bikes with these units and left them for 5 months alone in storage hoping I would not need to buy new batteries when I got the bikes out. When I got back, the green LEDs were illuminated on both units. Turned the keys and both bikes started up like champs. Batteries were strong cranking and kept fully charged. I have since moved the bikes to the new house and these units are on them constantly while we endure winter in the east. really really satisfied with this product. At 20 bucks each I already exceeded the value from them in saving me over $200 cost in new bike batteries. They saved me in this storage and now are holding me through winter. Enough said!!

Rated 5.0 out of 5.0 by Best auto trickle charger I've seen! Couldn't be better....just plug in, hook up and it does the rest, as advertised. December 10, 2014
Rated 5.0 out of 5.0 by Trickle Charger This was given as a gift. Recipient was pleased. Thank you. January 10, 2015
Rated 5.0 out of 5.0 by Best price for the best battery maintainer This is the best battery maintainer on the market. A good friend of mine recommended it as it is all electronic and does not require a transformer. Also Home Depot had the best price and I picked it up at my local Home Depot. January 3, 2015
Rated 5.0 out of 5.0 by Piece of mind having my battery maintainer Bought the 6/12 volt battery maintainer so I would not have to worry if there was enough charge on my battery to start my "classic" car. My car sits in a separate garage and I don't start it every week, sometimes not for a few weeks and at times the car has a hard time starting and I have to hook up the charger or jump it. Now with the battery maintainer, I never have to worry if there is enough juice to start my 1937 Dodge!!!! I wish I would have done it years ago. December 10, 2014
Rated 5.0 out of 5.0 by Great price Use this to keep my battery charged. Seems to do the job. February 3, 2015
Rated 4.0 out of 5.0 by Battery Trickel Charger I use this charger on my lawn tractor to keep the battery fully charged, especially in the winter. It works well for me, as it is small, portable and has long enough leads to fit from under my carport to the tractor. Best of all, the price is very affordable and it is very easy to use.
