Offers various connection types, but reliability can be inconsistent.

Device has a sturdy and well-crafted build.

Offers budget-friendly battery maintenance solution.

I've had the Black and Decker Battery Maintainer running for about a week now and I am, so far, very satisfied with the product. I use three other versions of maintainers, all of which work but are considerably more expensive, to maintain the batteries on my ATV's, motorcycle, boat and RV and so far this maintainer works as well as the others. It offers three connection modes, battery terminal clamps, cigarette lighter plug and hard wire directly to the terminals. I prefer to hard wire directly to the terminals and the quick connect plug makes it a lot easier to disconnect when I am ready to play and reconnect when I'm done. Just remember this is not a battery charger! It will keep a fully charged battery functional and up to capacity but will probably not recharge a low or dead battery.

So far so good.

walmart.com

Just had it a few days. Easy to set up. Keeping the battery at its maximum voltage. My battery drained during the Coronavirus quarantine. It was at 2.5 volts (12 volt car battery) The trickle charger manual said it won't at less than 2 Volts. It didn't charge mine at 2.5 volts. So I got a jump and let it idle for an hour and got the voltage up to 12 volts, put on the trickle charger and it started working just fine. It was at max charge the next day.

Easy to setup.

I like the many attachments which make it easy to attach to my generator battery as a way to insure quick starts.  Idiot lights show if battery is fully charged or is charging, or if battery is bad or connection is wrong.  Good product.  My Champion generator battery can only take 1.5 amps so this is pefect.

Charger works

For the price this unit delivers. Both in 6 volts and 12 volts. It comes with multiple battery attachments which most of the other units out there do not. I used the permanent attachment on my garaged vehicle which rarely sees the road, and then I have the other two attachments remaining which I can use to 'spot' charge my other vehicle/lawn mower/generator batteries to keep them topped up and in their prime. I purchased this B&D Battery Maintainer due to a dead battery found on my garaged vehicle from less than 2 years new!!! The result of not much vehicle road use and a slow discharge brought the battery down so low it could not recover. Now I can spot charge it and keep it in prime condition and avoid another $120 plus battery purchase. I also have the advantage of using it with the other supplied attachments on my lawn mower, portable generator and other vehicles batteries. A great value.

Dual Charge Capability and Mulitple Attachments

There are battery maintainers that go for around $100 or more. So I was skeptical about this one only being $20, but gave it a shot anyway. First thing I notice is the plug accessories which are very cool. The device is simple to use and the most important thing is that it works. Hooked it up to my old jeep (battery was dead) it took about 2 weeks but charged the battery and keeps it charged. So I hooked one up to my boat battery and it was fully charged in 2 days. Will probably get a 3rd for my atv. These things are great and cheap.

Great product

This is a very nice trickle charger.  This is third one that I have purchased.  I use them on my Wave Runners and Motorcycle to keep the battery in good shape.  Before I had these trickle chargers I used to have to replace my Wave runner batteries every season but now they last several years.  I would recommend this trickle charger to anyone that is tired of replacing batteries prematurely

Black & Decker Battery Maintainer

I really like this.  It's easy to use, and connects with ease.  Indicator lights show whether it's accepting a charge or not, so it's easy to know if you didn't connect it properly.  Two modes, 6V and 12V, make for limiting the current easy too.  It was worth the money.

Just good product here-- nothing else to say

easy to use, works very well, had another one for about 4years (replaced due to an issue with moisture), used on seral vehicles, flooded and gel batteries, keeps them charged and strong, and has extended the life of the batteries. very happy, thats why i bought it again.

great battery maintainer

There is one green led that blinks on and off to indicate the battery is being charged. The same green led stays on solid when the battery is fully charged.  It trickles charges at 1.2A. I was charging a battery which had a good charge already. I wanted to bring in to a full charge.  I charged it for 8 hours and this charger never indicated a full charge -- a solid green led.  I am not sure if I would leave this trickle charger on all of the time.  it may overcharge the battery.  The charger that I recieved looked like a return. I am keeping it but I am going to watch it closely.

Okay as a 1.2 AMP Trickle Charger

It was pictured with a connection for a cigarette lighter and did not come with that.  The company's solution was to have me return the whole thing and suggest that the picture be taken down

Not all included

Had this for a short period of time... The bottom of the case is already melting from the extreme heat inside. This could be a fire hazard... Will return

Don't buy this unit could start a fire!!!
