Rated 5 out of 5 by from Great price and works great I bought two of these and they are working great. One is charging a dual battery system in my 91 Roadtrek and the other is charging a battery in my 94 GMC 1/2 ton. Both parked outside for the winter. I hooked them up properly (cables first - then plug it in) five days ago. Roadtrek batteries are both sitting at 13 volts. I just hooked up the GMC today and voltmeter shows that battery is charging. Questions about a dual battery system? - Let me know!

Rated 4 out of 5 by from Worked for me, but does not come with DC plug It took about 24 hours to fully charge a battery that was low on charge. The website is incorrect, it does not come with a DC plug. The box does not state there is a DC plug. Cost < $30 so I guess it's worth the money.

Rated 4 out of 5 by from Works great so far The meter shows 1.4A when it charging the battery (12V) which is match what the package indicates. About 400-300ma when LED is solid. Good price for 1.2Amp battery charger. The 6v/12v is loss but not a bid deal for me, if you really worry about that, put a tape on just in case.

Rated 1 out of 5 by from Useless as a winter under hood battery maintainer. This charger will not work at temperature below 0 Celsius making it worthless for me as an under hood battery charger/maintainer in winter. I have small trickle/maintainer chargers under the hood of all 5 of my vehicles. These chargers operate whenever the block heater for the vehicle gets plugged in which is typically at temperatures below -15 to -20 Celsius. I recently replaced one of my old chargers with one of these BM3B units and have been frustrated with lack of performance ever since. The instruction manual says if the green light is flashing then it is charging...This is not necessarily true. If the temperature if above 0 Celsius and the green light is flashing (flash, flash, flash) without any clicking noise then it is likely charging the battery. HOWEVER if the temperature is below 0 Celsius the green light will still flash but slightly slower and the flash will be in conjunction with a clicking sound. When this is happening, the charger is not charging your battery! What good is a battery maintainer if it does not work when it is needed the most...for me, that is in wintertime when the temperatures are below -15 Celsius which is when batteries begin to fail the most. It turns out that none of Black & Decker small trickle chargers will work for my application because of the same 0 Celsius limitation. These would be the awesome priceless little chargers for a great price if they worked below 0 Celsius, as they are now, they are worthless to me.

Je viens de me procurer un chargeur d'entretien automatique que je vais mettre sur ma voiture entrepos&eacute;e pendant 6 mois. Est-ce mieux de retirer le maintener de temps &agrave; autres durant cette p&eacute;riode pour permettre &agrave; la batterie de se d&eacute;charger.

(Black&amp;Decker 6v/12v battery maintainer Model # BM3BCA) Does this battery maintainer come with the 12v DC plug accessory?; the product information/description says it does but a user in the comment section says it does not.

Asked by: Grant
This accessory is sometimes included and sometimes is an optional accessory. The website has just not been updated. However if you need this accessory contact customer service and explain this to them and they can send you one. 1-877-571-2391

Will this charge a fully drained battery?

Asked by: Rav10
Yes, it will however it will take a very long time, depending on the size of the battery. This is a 1.2A charger.
