B&D way to go for maintainer.
The best maintainer on the market. One it has mounting holes, not to worry is never gets hot like other brand name. Two, when you unplug it the from you vehicle the unit shuts off, no blinking lights. It keeps my motorcycles battery fully charged. It cranked right over when I started it the other day. And lastly it has fairly long cords,but can be plugged into an extension cord where other brand must be plugged directly into the wall socket.Read full review

Works but not well..
One cant expect it to do much more than trickle charge (a slow, methodical charging) and it does that well. The problem is the indicator lamp. Mine, when first plugged in, will be red until its properly connected to the battery. When it sees a good connection and should blink green. It doesn't. Mine goes right into solid green which should indicate a fully charged battery. I've tested the battery and it was at low, barely holding 8v when it should be 12-13 fully charged.
But if I leave it on all night it will charge the battery well. It just wont blink indicating a ready state.
It should be:
RED= Not connected
BLINK GREEN= CONNECTED CHARGING
SOLID GREEN= FULLY CHARGED
But mine is:
RED= Not connected
BLINK GREEN= Never does
SOLID GREEN= FULLY CHARGED and or CONNECTED
Hope this helps someone...Read full review

Very useful and flexible tool.
This is a really well conceived and nicely executed product. The plastic seems a bit light but it has guards to protect it from getting shattered when the inevitable drop on the concrete floor happens. The transformer is compact and light making it less likely to slip out of your fingers or come unplugged from a wall socket. Nice long cords! I don't have to run extension cords all over the garage. Three modes of connecting to the cars triples flexibility. Having both 6 and 12 Volt is a HUGE thing for those of us with both older and newer cars. That doubles the flexibility. The price is not bad -- certainly better than competitive float chargers. This tool should NOT be compared to or confused with trickle chargers that can be purchased for a few dollars. This unit gives a slow, deep charge but it cuts itself off when the battery gets to full charge. Trickle chargers keep trickling even after the battery is topped up. This boils away electrolyte, it sulfates the battery, and it's not especially safe. The BM3B is one of the very few reasonably priced maintainers that can be used on wet, gel, and AGM batteries. For anybody who has purchased a super expensive Optima battery and then ruined it with a cheap maintainer, this is huge. Power demand is much lower than other float chargers. I ordered a half-dozen to try them out. Love 'em. Gonna order another dozen. Do shop around because there is variability in price -- unlike some other float chargers.Read full review

Battery Charger
Works well with 6V and 12V batteries. I use this charger for my motorcycle and car when stored for the season. Easy to use. Comes with few different battery attachments. Built durable.

12V trickle charger with plug for accessory port charging
good value item easy to use by plugging into cig lighter plug to keep batteries in my Freightliner truck charged . since I am not using the big truck all the time this charger is just what I needed to maintain full charge. time will show how durable it is but at this point I am happy. Quick shipping and no extra handling charges are also part of this good value purchaseRead full review

Great Quality and Value
These are more expensive in retail stores, and batteries can be very expensive. This is simple to hook up and maintain. I wish I bought one earlier. Great to have year round, but certainly during cold winters. I hooked it up to my gel battery, and I will bet I get years of life out of my battery, which is important, and it will save money in the long run. I highly recommend the purchase.Read full review

Super Charger Maintainer
Easy to operate, 12 or 6 volt capable. This is a durable charger that I use for my 6 volt batteries on my toy hauler. I couldn't be happier. These are Black and Decker brand and they live up to the name. Great item at a great price.Read full review

not the best but works
so I purchased this and had just bought a new battery for my motor bike aand so I put this charger on it hopeing it would get it charged and so I left it over the corse of 2 days charging, it was charging it but not very well. I had to throw it on my father's charger over night and it charged the battery right up and then I am able to maintain it with this charger. so all in all it works just not as strong or good as I was expecting. and the casing and everything seem of nice good quality as wellRead full review
