12V Sealed Lead Acid Battery Charger, 6A Maintainer Three Trickle Charger with LED Digital Screen for Car Boat Marine

The product does indeed work as a good battery charger. However, it EXCELS as a radio jamming device! I cannot believe this unit passed any sort of RF emissions testing. All of my AM radio bands are pretty well unlistenable, especially below about 800 kHz, which is where some of my favorite talk and news radio stations transmit in my area (southern Californa). For the life of me, I could not figure out why I had all this interference on my bathroom radio, and my kitchen radio, until I accidentally unplugged this charger and VOILA! My garage radio immediately cleared up! So I checked my kitchen/bathroom radios and they, too, were clear. Plugged the charger back in and the noise reappeared. I would not recommend this charger unless radio reception isn't important.

The battery charger worked fine for first half dozen batteries that I charged. Then the screen locked o 13.5 V. and 00.0 amps, indicating battery was 100 % charged, which it was not. It was actually not putting out any voltage or current. Now when connected to A.C., it indicates 13.5 v even though no battery is connnected.

I bought one to see how well it'd perform re-charging the kids power wheels batteries. Well... I bought 3 more! Works fantastic. I have about 6 different types of "trickle" chargers and these are by far my favorite.

Receieved it with a broken screen

junk do not waist your money. It shows it is working even when your battery is going dead.

Love this little thing. Does a lot for the money.

Great buy

Práctico pero lenta la carga
