BLACK+DECKER BC6BDW Waterproof Battery Charger/Maintainer (6 Amps)

This is a great little charger all the way around. It is very easy to operate and it does a great job. Just plug it in to a household outlet (or to another vehicle's cigarette lighter), clamp it on to your vehicle battery, and let it work. It has a blue light comes on immediately to let you know that it is properly connected to its power source. It also has a graduated three-light system that lets your know the status of the charge (battery not fully charged/battery fully charged/fault-problem with connection). This charger can fully charge any vehicle battery that is capable of being recharged. I use it as a trickle charger for my Toyota Tacoma pickup. I also have a Black & Decker BC2BDW charger, which is EXACTLY like this one, but a little smaller. I use that one as a trickle charger for my little Toyota pickup. Both have worked flawlessly. These chargers work well as either the charger of a dead battery, OR as a trickle charger (battery maintainer). This model is designed to remain hooked up continuously without over-charging the battery. It has a smart sensor. These chargers are also waterproof, although I recommend that -- if possible (especially in maintainer usage) -- that you mount/place them under your vehicle hood while in use. This will keep them out of the direct weather and probably add many, many, many years to their life. I highly recommend this charger and this entire family line of chargers just like it.

This Battery Charger is a very good thing to have around. You can leave it charging overnight and not worry about it. It is a very small device but also very effective. There was something wrong with my ignition that which caused the car not to start and the battery to run down after many starting attempts. Fortunately, this charged up the battery to full strength, so it was clear that the problem wasn't the battery (replacing the ignition switch did the trick). My preference would be always to charge the battery when possible rather than jump start the car and this works perfectly for charging.

I had gone to NY for a few weeks but it ended up being an almost 2 months long trip. My Yamaha WaveRunner was left unused (with some electronics and security devices that do use a bit of battery over time). My alarm system alerted me that the battery was at 10% charge but I was still unable to make it back to Florida. When I got back, sure enough, there was not a peep from the battery when I tried to use the vessel. I was wondering if my battery was in that "so discharged that this charger won't recharge it" condition, which several people have pointed out to. I left the charger plugged in with its sturdy clamps on the jet ski battery, placed the charger in the footwell, plugged it into my shore power, and left it overnight. I am a late night person and went back to my dock a few times during that 12 hours period and the charging lights did not seem to show that my battery had been charged up. So, it was still a bit of not knowing. But, fortunately for me, the charger had fully charged up my battery and I have brought the charger inside for safe keeping. It is good to know that it worked as I needed it to. I would prefer to give it 4.5 stars but that is not an option so I am giving it 4. The reason I cannot give it 5 stars is that it is annoying to know that this higher power higher priced item comes with fewer accessories for charging options than their own cheaper models. Additionally, maybe I missed it in the Amazon description, but they should make it very clear that it will not charge fully drained batteries. I was lucky not to have that situation but it would have been a time and energy (no pun intended) wasting exercise to leave it on all night and day, still have a dead battery, and then be calling Amazon for a return. Lastly, and this is a big user experience "UX" design issue, just having a solid LED for 12 hours tells you nothing whether it is just putting out voltage to the battery or if the battery is actually accepting it (e.g. a blinking LED the rate of blinking to indicate how much charge/current is flowing into charging the battery) would have made it a lot easier to know. Otherwise, I am glad I got it, glad it arrived on time, and charged my battery. I will probably move it into my car trunk to keep with me when I travel and if I ever drain that battery.

I love that this has an option connect to the DC connector inside the car(rather than only being able to use the battery clamps.. though both are included). This is a slow charger - might take 10+ hours to charge a completely drained battery - but you can usually start the car pretty quickly after beginning to charge. Just make sure you finish charging later! Super easy to use, I've had it for a month and I love it.

well, my kids have used this charger a few times and i finally used it last night. It works well and has a yellow 'charging light' and a green 'done' light/ there is a bright blue light to tell you it is on too. plus and 'idiot' light incase you hooked it up wrong. sense it says it is water proof, i am hoping it lasts a long time. I have had it a month or so and so far so good!!! best value for price - beats harbor freight!!! :)
